Steven Universe (character)

"♫ I will fight to be everything that everybody wants me to be when I'm grown! ♫"

Steven Quartz Universe is the titular main protagonist of the show of the same name. He is the son of Greg Universe and Rose Quartz/Pink Diamond and the first and only member of human descent and hybrid nature of the Crystal Gems and new monarch of the Great Diamond Authority.

A human-Gem hybrid as a result of his parentage, Steven is an extraordinarily unique being with innate powers beyond that of both normal humans and Gems. While only a child, Steven has steadily grown from a tag-along to the Crystal Gems into the team's unofficial leader thanks to his kind-hearted nature and resourcefulness. Though he is part of a monumental legacy, Steven is devoted to fulfilling his destiny as protector of humanity, just as his mother was before him.

Appearance
According to Pearl and Vidalia, Steven takes after both his parents, Rose and Greg, respectively. He is relatively short with a thick, stocky build. He has curly black hair and full black irises. He wears a pink T-shirt with a gold star in the center of it. He also wears cuffed blue jeans and salmon-pink flip-flop sandals. His gemstone, a pink diamond, which he inherited from his mother, is where his navel should be. As revealed in "Steven's Birthday", while he is fourteen years of age, he has the physical appearance of an eight-year-old.

Personality
"He is a super-excitable, hammy kid." Steven is an optimistic, friendly, outgoing, soft-hearted and carefree boy with a happy-go-lucky attitude that is appreciated by many of the citizens of Beach City in one way or another. He is musically inclined, a trait he inherits from his father, with a propensity for breaking out into song and occasionally playing on his ukulele. Steven is also very compassionate, something which Pearl notes he inherits from his mother, and he treasures his friends and family. He is friendly toward almost everyone he meets (even to his detriment), rarely holds grudges, and is very non-discriminatory, never treating anyone with prejudice, even his enemies. No matter the situation, Steven will always go out of his way to support his loved ones, even if it means putting his life on the line, and he will avoid resorting to violence if possible. He would much rather make a compromise and choose to reason than fight back.

Steven looks up to his caretakers — Garnet, Amethyst, and Pearl — and considers them family. He wants to be a great hero just like them, and he is eager to go on adventures with the trio, both to prove his worth and to have fun exploring strange lands. Despite his under-developed magical power and lack of experience, he has proven himself to have much heroic potential through his resourcefulness, optimism, and confidence.

Steven is rather naive and socially oblivious, due to his isolated upbringing by the Gems. Steven has never attended a school, and before "Nightmare Hospital" had never been in a hospital or had his vitals taken. While Steven is often prepared to go on adventures at a moment's notice, he has a habit of biting off more than he can chew, requiring the other Gems to intervene. While Steven initially retains his childlike innocence and obliviousness to the dangers he is frequently put in, his encounter with the Homeworld Gems gives him a new level of seriousness about being a Crystal Gem.

This initially makes Steven self-conscious about his immaturity, and he gains resolve to outgrow it, although his misguided attempt becomes a source of self-inflicted misery as he tries to break off his friendship with Connie to protect her from harm. It was only Connie's sensible nature that stops him from going down a bad road and balances his resolve. Steven has since grown more mature and level-headed in dealing with strenuous situations, but his enthusiasm has remained the same.

His maturity has grown to new levels as he helps Lapis Lazuli and Peridot acclimate to Earth and continues to hone his powers. He is now more willing to fight than before to aid and protect his friends, though he is still willing to help anyone in need — even enemies, as seen when he tried to heal Jasper from creeping corruption in "Earthlings". Unfortunately this has also gotten him in trouble, as shown in "Bubbled" and "Room for Ruby", where trying to befriend Eyeball and accept Navy as new member of the Crystal Gems have ended badly: Eyeball tried to kill him when she believed that he was Rose Quartz due to having healing powers, and Navy turned out to have been lying to him the whole time in revenge.

"A great example is in "Bismuth" and throws something at her and yells, "Look out!" but they're fighting and she's actively trying to get him. It's very insightful to who Steven is. Violence is always the last resort. He'll always try to talk it out for better or for worse, it doesn't always go the way he wants it to."

Like his mother, he appears to be very charismatic; for example, easing a raging crowd in "Political Power", and motivating his friends and father into working out and helping Pearl to find her strength to fight Sugilite in "Coach Steven". His genuine kindness, sincerity, and capacity for empathy let him inspire friendship, trust, and love from most of the people he meets which enables him to mend others' inner turmoil and reach others who are otherwise closed off, most noticeably in the cases of Peridot and Lapis Lazuli.

"But the truth is, we rely on you. Your voice inspires us, binds us, reminds us why we promised to protect the planet. You need to be that voice. For them."

Steven is shown to have unique tastes in entertainment. He enjoys Crying Breakfast Friends! despite his dad and the Gems' inability to understand its appeal. Steven is a bit of a romantic and loves the ending of The Spirit Morph Saga for the wedding even when Connie disagrees. "Made of Honor" further shows his enthusiasm for weddings in the form of the wedding planner book he claims to have been putting together his entire life, and he shows great zeal in preparing for and performing Ruby and Sapphire's wedding in "Reunited".

Despite his naivety in some aspects, Steven still has a more grounded and practical outlook than his three caretakers, often correcting them on normal human interactions. Despite frequently going on many fantastic adventures, Steven retains a tendency to be easily impressed. He is quickly enamored with Bill Dewey's play, until Jamie points out its flaws. He is also shocked to find that his Watermelon Stevens are alive and admits that it should not have surprised him as much as it does.

While Steven is typically friendly and kind-hearted by nature, Steven's enthusiasm and excitability can get out of hand, and he ends up doing more harm than good. When this happens, he can be anywhere between obnoxious, overbearing, and simply rude. Steven tends to let his inhibitions go out the window when doing something theatrical, as seen in "Tiger Millionaire", "Steven and the Stevens", and "Sadie's Song". His alter-ego Tiger Millionaire is the best example of Steven letting his passionate side get the better of him.

The one and only time he has shown true anger and prejudice toward someone is Kevin in "Beach City Drift" for the way he treats Stevonnie. His dislike and desire to best Kevin lead him to fuse with Connie, and the anger Stevonnie inherits is strong enough that they hallucinate, causing the fusion to fall apart. It is Connie's sensible nature that convinces him to let his anger go.

Deep down, Steven feels guilt over his mother not being around, and a feeling of inferiority over not being able to live up to her reputation. He is unwilling to talk about this with the Gems due to thinking they blame him for Rose being gone. The only people he has opened up to about it are Amethyst, Bismuth, and the Cool Kids. He told Amethyst that the reason he is working so hard is that he is not Rose Quartz, and told Bismuth that he does not think he can live up to his mother's standards in the Gems' eyes.

In "Mindful Education", it is revealed that Steven harbors guilt over the unfortunate events upon Bismuth, Jasper, and Eyeball. Like his guilt over Rose, he tries to keep these worries secluded in his heart and tries not to think about it, convincing himself he had no other choice.

After it is revealed by Eyeball in "Back to the Moon" that Rose Quartz shattered Pink Diamond, Steven has become more independent and rebellious towards the other Crystal Gems and their authority over what he is supposed to know. In "Steven's Dream", he openly argues with Garnet for not telling him why he shouldn't find the broken Palanquin, figure out his dream, and why he is shedding a constant flow of tears. As he has discovered more about his mother and the effects her actions have had, he has started to show both anger towards her and guilt over what she has done.

"Storm in the Room" highlights Steven's anger and confusion toward Rose over her actions and how she "disappeared" to leave him to clean up her mess. "Lion 4: Alternate Ending" shows that he has become somewhat paranoid about anything having to do with Rose and her secrets and in "The Good Lars" has called her a war criminal. These feelings come to a head in "Are You My Dad?" and "I Am My Mom" when his friends are captured by Topaz and Aquamarine and he bargains to free them by offering himself instead as a way to atone for both his and his mother's actions.

"The Trial" highlights his resolve to atone for Rose shattering Pink Diamond, in that he immediately pleads guilty knowing that he would be shattered/executed. However, when Rose Quartz's crime comes into question, Steven was shocked upon the revelation of the flaws in his mother's crime and the possibility of a Diamond being responsible for Pink Diamond's death instead of Rose Quartz. Matt Burnett and Ben Levin have stated that he learned he was wrong about who Rose was, and wonders whether he has to carry the moral grayness that she had or if he can be stronger and different.

Steven's obliviousness can create problems even with those he cares about, as in "Dewey Wins" he thinks Connie should be grateful to him for giving himself up to Homeworld to save her, not understanding how he hurt her until suffering the same hurt when Dewey concedes the mayoral race in spite of all of Steven's hard campaigning and urging of the public to give him another chance; although, this particular obliviousness could be attributed to him not being ready at the time to face his own feelings over his surrender and everything he experienced on Homeworld, as well as having to deal with his loved ones and all the emotional anguish his surrender caused them. "Kevin Party" shows him confronting the harm he did when he reunites with Connie after a few weeks apart from her and apologizes to her for giving up and brushing off her feelings.

"A Single Pale Rose" once again changes Steven's view of his mother after learning that she was Pink Diamond. He tells Amethyst in "What's Your Problem?" that he is happy his mom wasn't a shatterer, but is still confused about her and her actions. "Made of Honor" and "Reunited" cement Steven's growth and maturity as he forgives Bismuth and accepts her back into the Crystal Gems with Bismuth claiming that Steven has become the real leader of the Crystal Gems, and as he convinces Blue and Yellow Diamond to stop fighting and reveals his identity as Pink Diamond's son/reincarnation.

"Learning about his mom, things he didn't realize, things aren't as they seem, it's hard for him to process all that. That's a big dynamic for Steven as the show goes on. He just wanted to meet his mom at first. He had all these questions about who she was and know that he knows he wishes he didn't in a lot of ways. He still doesn't know definitive answers about a lot of things. He was especially frustrated when the Gems wouldn't always tell him the truth about things or how things really were. That's going to be a struggle for Steven for a while. At this point, because I don't know the whole story, I can't say. I don't think Steven knows if he can at this point."

"Familiar" gives Steven a look into his mother's relationships with Blue and Yellow Diamond, and also leads him to realizes that he and his mother have something in common: they are/were the youngest members of the Crystal Gems and Diamond Authority respectively, and were frequently underestimated due to their immaturity, but also dearly loved and doted on like children by their peers. With this, Steven decides to embrace his mother's old role on Homeworld in order to help convince White Diamond to cure the corrupted Gems on Earth.

Abilities
Being a human/Gem hybrid, Steven is capable of using Gem magic, though it is unknown if he possesses all the abilities of a pure Gem, such as retreating to their gemstone when taking fatal damage. As associated with his gemstone, Steven's powers are maternal in nature and his control of his gemstone is based on emotional clarity.

Steven has shown to have some abilities of a regular Gem, but sometimes has little control over them due to not receiving enough training. He can warp using the Warp Pads and bubble objects and gemstones to be teleported to the Temple with seemingly full control. He is not strictly oxygen-dependent and is vacuum-resistant as shown in "Ocean Gem" and "Space Race". He also shows that he is able to fuse, as he can fuse with Connie to form Stevonnie.

While in the beginning, they tend to fuse spontaneously when they dance and while thinking about each other, by "Beach City Drift" they fuse and re-fuse into Stevonnie at will. Furthermore, he has also been shown to be able to fuse with other Gems as well, as he first fused with Amethyst to form Smoky Quartz in "Earthlings". Steven is also capable of shapeshifting, but he has not yet learned to fully control it. His first attempt in "Cat Fingers" was disastrous, temporarily turning him into a cat monster. He has not been able to change his form entirely but can freely shapeshift parts of his body as seen in "Too Short to Ride".

His greatest feat in shapeshifting is seen in "Steven's Birthday", where he is able to use shapeshifting to make himself appear older. Despite his happy-go-lucky and cheerful attitude, he shows himself to be a competent shield fighter and is able to hold his own in most situations with his skill consistently increasing due to practice.

Despite being educated in an isolated environment and never attending conventional school, he possesses a good deal of knowledge not only on general topics, but also in scientific and technical fields like physics, chemistry, and geography due to being educated by the highly intellectual Pearl. However, due to the Crystal Gems' own obliviousness about some human activities, he is quite oblivious about some social terms, like "nuclear family". The prime example is during his conversation with Connie about a family gathering in which Connie mentions the concept of a nuclear family, which makes Steven think that she thinks the Crystal Gems are radioactive. Another example is that when Connie introduces Steven to her favorite novel series, Steven had no idea about the order of the books in the series and was reading them out of order.

Fusions

 * When fused with Connie, they form Stevonnie.
 * When fused with Amethyst, they form Smoky Quartz.

Natural Abilities

 * Fluctuating Age: As revealed in the episode "So Many Birthdays", Steven can manipulate his age through his state of mind. Steven's age depends solely on how old he thinks he is. Uncontrollable age-changing could also potentially be caused by his emotions like most of his powers.
 * Shapeshifting: Steven possesses some level of the natural shapeshifting abilities typical of Gems, which he first displayed in "Cat Fingers" when he shapeshifts his hands to have cats for fingers, but he lost control of this rather quickly. As of "Too Short to Ride", he is shown to be much better at using this ability than before, being able to stretch various parts of his body at will repeatedly, though as with Amethyst he can only do this for a certain amount of time and his half-human nature puts more of a strain on his body than it would a Gem. However, he has not yet demonstrated the ability to transform his entire body into something else.
 * Superhuman Strength: Steven occasionally performs feats of strength that would be impossible for a human boy his age, or even a grown man. In "Together Breakfast", Steven is able to lift and force the Together Breakfast in its mutated state into the lava pool in the Burning Room without the other Crystal Gems' assistance. He also displays a large amount of strength in "Arcade Mania" when he rips off the top of the Meat Beat Mania arcade game to break Garnet from her trance.

He displays an even further amount of strength in "The Return" when he smashes Greg's van's dashboard with a single punch, apparently hard enough to both shatter it and activate the airbags. In "Joy Ride", he is able to move Jenny away from the Escape Pod with little effort. Later on in "Friend Ship", he is shown to be strong enough to throw his shield hard enough to stun Peridot. When Peridot is unable to open the lid to the power grid in "When It Rains", Steven is able to open it with little effort, though this may have been for comedic effect as opposed to an actual feat of strength. He is able to rip off the control panel from the drill machine when it malfunctions in "Too Far". In "Drop Beat Dad", he easily lifts a crate of musical gear, a task that requires two adult humans to achieve.

As Gems are much stronger and durable than their appearance would indicate, Steven's superhuman strength is most likely passed down to him from his mother. In even more recent episodes, his strength is even more evident, as he was able to throw a large stone statue back at Bismuth, hurl a large rock at Amethyst, and throw Peridot into the air like a ragdoll. As seen in "Future Boy Zoltron", Steven's strength is underestimated and unintentional in situations by even himself, as tapping the Zoltron robot made it fall over and shatter into pieces. In "The Zoo", he punched his father with enough force to knock him back several feet and easily carried him overhead as he ran from the Zoomans.

Steven's strength was further demonstrated in "Tiger Philanthropist", when he managed to fight off several conditioned adult men without tiring, including being able to lift an adult male human above his head and throw him a considerable distance. In "Lars' Head", he is shown to fairly easily push a boulder that both the Rutile Twins and Rhodonite (a fusion) combined were unable to move, causing the twins to even remark "Woah, strong." while all three Gems stared at him in awe. In "Back to the Kindergarten", Steven carried a rock stack that was at least a few times taller than himself while showing no strain.
 * Martial Arts: Steven has been shown to exhibit martial arts moves while wrestling during "Tiger Philanthropist". Due to his superhuman strength, these moves can easily injure or knock out other humans when used by Steven.
 * Superhuman Speed: As shown in "Greg the Babysitter", Steven has the power to travel faster than any normal human.
 * Superhuman Durability: As shown in "Steven vs. Amethyst" and "Bismuth", Steven is more durable than what his human physiology and stature would lead one to believe. Befitting his nature as a half-diamond Gem, his body can take a great amount of punishment, as seen when Amethyst swings him down from the air and into the floor of the Ancient Sky Arena, he is able to stand up and continue fighting despite being seen with torn clothes, scratches, and bruises. In "Bismuth", when Bismuth tossed a training statue at Steven and slammed him into a wall during their fight, he emerged with several scratches yet was not badly injured. In "Adventures in Light Distortion", Steven's durability allowed him to handle the full force of faster-than-light space travel. While the other Crystal Gems were unable to hold their physical forms together, Steven was not only able to survive, but also show no sign of internal or external injuries.
 * Gem Weaponry Resistance: Because Steven is half-human, he is resistant to anti-Gem weaponry. He can pass through the yellow destabilization fields used in the Gem Warship and can grab the live end of a Gem Destabilizer with only mild discomfort. It is unknown what long-term exposure would do to him.
 * Intelligence: Though never directly stated, Steven is shown to be extremely intelligent in his own right. He is a natural problem solver, as most of his early adventures relied on him using intelligence and creativity to get himself out of trouble without the use of his powers. He is also able to converse with the highly intelligent Connie on an equal footing since they first met. For much of the early series, his intelligence was overshadowed by his immaturity, something that has faded as he has matured and shown how deeply he thinks about things, particularly what he has learned about Rose Quartz, even though he actively tries not to.

Unique Abilities
Due to possessing Pink Diamond's gemstone, he shares most of his unique abilities with her. He appears to have become quite skilled in wielding it as he was able to use it in conjunction with his protective bubble and defend against Pearl's strikes. Unlike some other Gems, instead of "pulling" his shield out of his gemstone, it appears over his arms similar to Garnet's gauntlets appearing over her hands. As of "Friend Ship", he has become completely capable of summoning his shield at any moment he requires it, even being able to scale his shield large enough to defend the Crystal Gems. It should be noted, however, that overuse of his shield exhausts Steven (such as using it three times in one day), though he has since overcome this weakness. The shield is remarkably durable. The greatest testament of its durability is shown in "The Return" when it was able to withstand a charged shot from the Gem Warship. As of "Crack the Whip", Steven can summon his Shield as many times as he wants without tiring, even summoning more than one. This shows that his exhaustion was possibly due to inexperience. The shield also has reflective properties strong enough to reflect a laser fired from a scanning Robonoid, as seen in "Off Colors". As seen in "Steven vs. Amethyst", Steven can boomerang his shield off of several targets, causing it to return to his hand. His shield also has razor-sharp edges and can cut through substances as tough as a solid rock before returning to him, hitting Amethyst in the process, showing Steven's growing skill in this technique. The shield may also have potential to damage metal, as seen in it's debut in "Gem Glow," where Steven got so excited, he accidentally had it ricochet off the roof, floor, and walls of the house on the Crystal Temple, until it hit Steven's TV, impaling and damaging it. He can also heal common human injuries and conditions, seen when he healed Connie's eyesight in "An Indirect Kiss" and Greg's broken leg in "House Guest". During the end of "House Guest", the duct tape used to fix the Geode has the same sparkle effect as his saliva, and it is speculated that the duct tape replaced his spit, although the shine could've been used as an effect. In "The Test", Pearl remarks to the other Crystal Gems that he has lost his healing ability and that their test should hopefully increase his confidence and therefore prevent him from losing any other abilities. His loss of healing abilities could be purely psychosomatic. Peridot asked Steven to fix the Homeworld Warp with his saliva in "Catch and Release", suggesting it can be used to heal more than just Gems or humans. In "Monster Reunion", Steven's healing abilities came back to heal Master of Ceremonies Bear Bear, showing conclusively that his powers affect inanimate objects, and is able to partially heal the Centipeetle Mother. In "Earthlings", Steven attempted to heal Jasper of her creeping corruption but was thrown back. In "Bubbled", Steven successfully heals Eyeball's cracked gem. In "Kiki's Pizza Delivery Service", he helps Kiki battle her inner demons in her dreams. This ability has primarily come to light while other beings are under emotional turmoil. "Kiki's Pizza Delivery Service" shows with Kiki Pizza that Steven can also enter the dreams of other humans, but also that repeated use of this power can physically exhaust him, as sleeping in this state seems to provide no restful benefit that would otherwise be gained from typical sleep. In "Steven's Dream", he shows a strange development of this ability, in being able to subconsciously see through the eyes of Blue Diamond, while crying her tears. This can even happen when he's awake, if in close enough proximity to her, though this may be a result of Blue Diamond's own empathetic powers seen in "The Trial".
 * Shield Proficiency: Steven can summon Rose's shield. Because Steven's powers are maternal in nature, he is required to feel a strong need to protect and help others to call his shield out. Early on, he had little to no control over how to summon it, only calling it forth by chance or when in mortal danger. As of "Sworn to the Sword", Steven is now able to not only summon his shield with little effort but also increase its size at will.
 * Projectile Shield: Steven, when in great excitement, can throw his shield as a projectile with great speed and power. In "Friend Ship", he weaponizes it as a ranged attack against Peridot, hitting her in the head with enough accuracy to temporarily stun her. In "Crack the Whip", Steven throws two shields at once in a sparring match with Connie.
 * Shield Vibration: On certain occasions when Steven's shield is hit, it emits an audible vibration that disables magical constructs. In "Ocean Gem", it destabilizes Lapis Lazuli's water clones when a ball of water hits Steven's shield. It also seems to play a brief role in "Sworn to the Sword", when a Holo-Pearl attacks his shield, and it promptly deactivates (the same sound in the former episode can be heard as it does).
 * Tag-team Combat: Due to the close bond they share, Steven can coordinate his shield techniques perfectly with Connie's swordplay, such as fighting back-to-back to defend and attack simultaneously or catapulting Connie from his shield for a powerful lunge attack.
 * Dual Wielding: As seen in "Crack the Whip", Steven is able to manifest more than one shield.
 * Healing: Steven's saliva has the power to heal the injuries of both humans and Gems, and even inanimate objects. Steven's healing capabilities have not yet been seen to the full extent of his power, but he is shown to be capable of healing cracked gemstones as seen when he healed Lapis Lazuli in "Ocean Gem".
 * Resurrection: Like his mother, Steven possesses the ability to resurrect the dead with his magic tears. The recipient turns pink and gains special abilities, such as the ability to grant access to Lion's Dimension through their hair. Two known cases of this are Lion and Lars.
 * Corruption Reversal: As demonstrated on Centipeetle in "Legs From Here to Homeworld", Steven, along with Blue Diamond, Yellow Diamond, and presumably White Diamond, has the ability to reverse the effects of the Corrupting Light on Gems. However, it is implied that this is only temporary without the power of all four Diamonds.
 * Phytokinesis: Like his mother, Steven possesses limited control and influence over plant life. Using his healing saliva, Steven is able to grow sentient and sapient flora by licking plant seeds. In "Watermelon Steven", Steven discovers he has the ability to grow watermelons shaped like himself. They act as his bodyguards, but they are not directly under his control, and the Watermelon Stevens ignore his orders and attack whoever they think is threatening him, suggesting that he does not have full mastery of this ability thus far. It seems that this has changed, as once Pumpkin was brought to life, it was completely non-hostile and possessed its own opinions of others. It is also possible that, in the case of Pumpkin, Steven had full knowledge of the ability and thus control over it, whereas in the case of the Watermelon Stevens, it was accidental.
 * Pebble Animation: As demonstrated in "Familiar", Steven's sweat can turn inanimate pebbles into living Pebbles.
 * Bubble Shield: Steven can summon an incredibly durable bubble, as shown in "Bubble Buddies". The bubble encases him and others that he is protecting. In "Sworn to the Sword", it is shown that Steven is capable of summoning it reflexively, as he instinctively summons his bubble to protect himself and Connie due to his wariness of Holo-Pearls as a result of the events in "Steven the Sword Fighter". In "Nightmare Hospital", it is shown that Steven can expand his bubble to push away enemies. In "I Am My Mom", Steven used his bubble to free himself and his friends from Topaz, though it required a great deal of concentration to do so. In "Bubble Buddies" and "Bubbled", it is implied that the bubble can generate its own internal atmosphere, as Steven and Connie could survive in the bubble for hours despite it being air-tight, and Steven is even able to breathe inside one he had just generated in the vacuum of space.
 * Spike Bubble: As shown in "Steven vs. Amethyst", Steven can morph his bubble in such a way that sharp spikes appear along its surface.
 * Long-Range Bubble: Steven can stretch a side of his bubble into a small tunnel that connects it to another bubble.
 * Expand and Shrink: Besides the bubble offensively popping in "Nightmare Hospital", it has shown the ability to grow larger and smaller in "Bubbled".
 * Popping: Steven can "pop" his bubble to knock surrounding enemies back, as seen in "Nightmare Hospital", where he knocked much larger Gem mutants back by popping his bubble. His bubble will also pop if he is startled, as seen in "Sworn to the Sword", when Pearl startles Steven, or if immense pressure is applied to the bubble, as seen in "Gem Hunt" when the Snow Monster popped Steven's bubble by stomping on it.
 * Steven's bubble is incredibly durable. However, it is better at withstanding short, narrow bursts of pressure, such as being hit with a harpoon, than a large amount of pressure constantly being applied over a large area of the bubble, such as in "Nightmare Hospital", when the Gem Mutants hit Steven's bubble, the pressure causes little ripples to spread across the bubble, and in "Gem Hunt", when the Snow Monster stomped on his bubble with enough force to cause it to lose its circular shape and pop.
 * The extent of the bubble's durability is unknown, although it has survived most of the following:
 * The tremendous pressure of an ocean trench ("Bubble Buddies").
 * Being crushed by a falling Injector ("On the Run").
 * A shot from a death ray at point-blank range ("Say Uncle", non-canon).
 * A spaceship crash ("Jail Break", "Jungle Moon").
 * The vacuum of space ("Bubbled").
 * Empathic Telepathy : In "Horror Club", Steven is able to sense the Lighthouse Gem Monster's presence as well as its emotional state. In the episode "Chille Tid", it is shown that Steven can communicate with Gems through his dreams. Steven talks to Lapis Lazuli mentally as he was dreaming. He also saw Jasper and Malachite in the same dream at Malachite's Realm and they noticed him as well. Steven was later shown in "Gem Drill" to be able to communicate with a distressed Cluster while it was struggling to form.
 * Mind Transfer: First shown in "Super Watermelon Island", when he is able to take control of a Watermelon Steven, Steven is able to transfer his consciousness into another living being he has a connection with while his own body is asleep. The true mind of the host body lays dormant while he is in control of it. The full extent of this ability is unknown. In the "The New Lars", Steven has shown to be able to possess someone (in this instance Lars) he thinks about while he sleeps.
 * Mind Link: First shown in "Steven's Dream", Steven is able to link his mind with another being. This power allows Steven to feel the target's emotions and see the world through their eyes. For example, if the target is crying, Steven will cry as well, regardless of his own current emotional state. When Steven sleeps, his dream will be whatever the target is looking at. Steven does not have to willingly link minds with a person in order for this power to work since he did not originally know his mind was linked with Blue Diamond.
 * Aura Projection: In the episode "Reunited", while his mind was linked to Blue Diamond and Yellow Diamond, Steven was able to manifest and project a powerful pink aura, which in turn convinced them that he was truly Pink Diamond reincarnated. This is something only a Diamond has been shown to be able to do.
 * Aura Blasts: In the episode "Reunited", Steven has the power to generate powerful energy blasts and shock-waves capable of easily affecting Blue Diamond and Yellow Diamond.
 * Astral Projection: It is shown in "Reunited" that if Steven is knocked out hard enough, his mind will go into an astral dimension while his body remains comatose. While in this state, he cannot interact or communicate with anyone in the physical world unless he phases through them. It is unknown how Steven can return to the physical world on his own. Steven used this new ability to inspire his teammates to keep fighting and convince the Diamonds to halt their attack.
 * Speed of Descent Regulation: As shown in "Steven Floats", Steven, like Rose, can levitate his body and even manipulate its gravity based on his emotions. When he thinks happy thoughts, he floats slowly to the ground, while when he is sad or angry, he descends much quicker. While floating slowly, anything he touches will also float just as slowly, no matter how large. This also allows him to jump higher than normal, having to be able to jump up to the temple's face and even above the clouds.

It was first seen in "Rose's Scabbard" as Steven leaps to a floating land island to reach Pearl, however, her turning to suddenly look at him causes him to break in concentration and fall to catch himself on the island's roots. Steven is shown to have some control over his powers in "Steven vs. Amethyst" and in "Monster Reunion" when he easily leaps up to get to Centipeetle's bubble and safely descend again. He displays his ability to jump extreme distances again in "Steven's Dream", when attempting to catch Blue Diamond's ship, but is blasted back by the ship taking off.
 * Electrical Interference: In "Maximum Capacity", Steven appeared to be able to control Greg's TV based upon his emotion. For instance, when he was shocked, the television went to static. However, like Rose, it is unknown if this is an ability or if this was for dramatic effect.

Attack the Light
Steven acts as the support character in Steven Universe: Attack the Light. He is unable to be damaged and carries the items for the team. He sports the most moves in the whole team. However, none of his moves cause damage, except for the counter for Bubble Shield.
 * Encourage: A move Steven has from the start. Steven encourages one of the Crystal Gems, healing them by 10 Harmony. Upgrades to this move increase the healing amount by 5 each time, ending up as a maximum of 30 Harmony. This move takes 2 Star Points and is best used as a substitute in battle for items.
 * Bubble Shield: Steven uses his bubble shield to encase a Gem in it, protecting them from 1 hit. When they counter in the bubble, the enemy that is attacking takes damage, provided that the strike was melee. Upgrades to this move decrease the Star Point cost from 2 to 1.
 * Escape: The name says it all. This move costs 4 Star Points and gives the Gems a chance to escape. Upgrades to this move increase escape chances and reduce the cost to 3 Star Points. Use only in dire circumstances.
 * Ukulele: Steven uses his ukulele to play a song that has a variety of effects depending on the song. Each one must be unlocked separately.

Cartoon Network: Battle Crashers
Steven is the most durable character in Cartoon Network: Battle Crashers. However, he is one of the slowest and can not jump high. He is unlocked on the first level and will gradually gain more abilities as he levels up.
 * Shield: Steven can summon his shield for protection from enemy attacks. It surrounds his body until the special meter runs out.
 * Laser Light Cannon: This is Steven's most powerful attack. Steven summons the Laser Light Cannon and fires it in the direction he is facing for a powerful long-range attack. This attack consumes energy from the special meter, however.
 * Super Move: When Steven gets a Walky Talky power-up, he can summon Alexandrite to shoot a beam of energy, damaging all enemies on screen.
 * Limited Invincibility: When Steven grabs a Cookie Cat power-up, he will be invincible to all enemy attacks for a short amount of time.

Save the Light
In "Save the Light", Steven retains all of his abilities in "Attack the Light" (Minus the Escape option) and has some new abilities. In this game, he can take battle damage and get knocked out, but now, he can actually fight and has 2 damaging attacks: the Shield Dash is his basic attack where he dashes toward his target with his shield over his arm, damaging enemies in his path and knocking them back, and the Super Duper Shield Dash, a stronger version of the regular Shield Dash that does higher damage, double knockback, and is GUARANTEED to give lucky strikes!

Weaknesses

 * Hybrid/Unique Physiology: Due to his parentage, Steven has the disadvantages of being both a Gem and a human being at the same time. This has been displayed and exploited on numerous occasions.
 * Power and Control Loss: He often has little to no control over his magical abilities, which tend to fluctuate erratically from time to time, such as when his father faked his leg still being broken in "House Guest", which cost Steven the healing powers of his saliva until the events of "Monster Reunion", much to Pearl's anger and dismay. It is later learned that his abilities are tied to his mood: if happy, he generally has access to the majority of them, but if he is angry or depressed, these abilities will either malfunction or fail to work entirely.
 * Immaturity: Throughout much of the series, Steven's greatest weakness was his immaturity. Despite being brave, caring, intelligent, and quick-thinking, he often let his youth, childish ego, and excitability get the better of him, causing problems or making problems worse. This has faded as he has matured, and has become stronger and less childishly excitable.

Rose Quartz/Pink Diamond
"For my whole life, I've been hearing stories about you. About how amazing you were, that you were so kind and loving. And every time I'd see that painting of you hanging in the Temple, I'd be inspired, and reminded of how much I had to live up to." Rose is Steven's mother, although he never met her face to face since she gave up her physical form to create him, and he only hears about her. Rose's absence left a particular void in Steven's life, as he grew up without a motherly figure to love. Steven is therefore unsure of what to feel about her despite wanting to, which is rather difficult for him as everyone else knows how to feel about her. As put by Steven himself in "Steven Floats", his feelings for his mother are complicated. Regardless, Steven is willing to defend Rose, like when he snapped at Lars for calling her weird.

After Steven had got to see the video tape Rose had left him in "Lion 3: Straight to Video", he was moved to tears when she expresses her love for him and grows more curious about the person Rose was. When Steven is sometimes troubled by the burden of being a Crystal Gem, he takes solace in continuing Rose's legacy by protecting the world like she wanted him to. As revealed in "Steven vs. Amethyst" though, he has doubts that he cannot measure up to Rose's greatness, which is why he works diligently to become a worthy successor to her legacy. He has also developed a habit of clutching his gemstone when he has something on his mind, possibly to seek support from Rose.

Steven harbors great feelings of guilt over Rose giving up her "life" to give birth to him. He keeps this hidden deep down inside of him and rarely expresses it. One notable exception is in "Joy Ride" where he confesses to the Cool Kids that he suspects that the Crystal Gems are blaming him for Rose not being around anymore, shocking the teenagers. He has also felt that he will never live up to the standard set by his mother in the eyes of the other Gems and is one of the reasons he is training harder to master his powers and combat skills. In "Earthlings", he tells Amethyst that it sucks not being like anybody, expressing his frustration of not being as powerful or skilled as his mother.

"Back to the Moon" and "Bubbled" cause Steven to have even more doubt on what he thinks about Rose after learning she shattered Pink Diamond during the Rebellion, first mentioned by Eyeball, then confirmed by Garnet later on. In "Mindful Education", one of Stevonnie's hallucinations is the giant head of Rose Quartz staring down menacingly at them, further highlighting Steven's doubts on what he should think of his mother.

This doubt Steven feels towards Rose is further developed in "Storm in the Room", where he feels uncomfortable by Rose's painting in the Temple. Steven is fully aware that the Gems have portrayed Rose as a perfect and loving being, but he knows there is much more to her. He enters Rose's Room to get answers and has the room create a manifestation of Rose for this purpose. In the room, Steven is initially nervous about being around Rose but gets along with her as they participate in activities such as playing video games and football. Steven feels nothing but joy that he can finally be with his mother and even gets emotional. But he soon realizes that the room made Rose exactly how the Gems portrayed her to be: the perfect, loving being. This is because Steven wants Rose to be that way. However, he once again realizes that he wants to learn about Rose's darker side, which brings out how he's been feeling about Rose.

"I've learned things about you. Things you wanted to keep secret. You locked Bismuth away inside Lion, because she wanted to shatter Gems, and you never told Garnet or Pearl. But then you shattered Pink Diamond. Now all of Homeworld has it out for Earth, and the Crystal Gems, and me! You put us all in danger and you just... disappeared! I finally know the truth. I know what you are: You're a liar! I thought you never wanted to hurt anyone, but you hurt everyone! How could you just leave Garnet, and Amethyst, and Pearl, a-and Dad? They don't know what to do without you! Maybe they didn't matter to you as much as hiding from the mess you made! And that's why I'm here, isn't it? Did you make me just so you wouldn't have to deal with all your mistakes? Is that all I'm here for?"

Rose then reassures Steven that she didn't make Steven just so she didn't have to deal with her guilt and that the tape she left him is proof that she really wanted him and let him exist. Steven then understands and realizes that Rose didn't make him to just be a scapegoat. However, he is still paranoid about her and her secrets as seen in "Lion 4: Alternate Ending". In "Are You My Dad?" and "I Am My Mom" he comes to a resolution about his feelings for Rose when he gives himself up as Rose Quartz to Aquamarine in order to both save his friends to atone for both their actions that led up to that point. In "The Trial", he pleads guilty even knowing that he would be shattered/executed, feeling that he was responsible for Rose's actions and deserved to suffer her punishment.

"Steven is really going to have to turn inward and face himself. Throughout the show, he's put everyone else first, and his main goal has been to become the person his family wants him to be. That's got to shift. He's got to accept that it's impossible to fill the shoes of his mother, Rose Quartz. She was always barefoot."

After it was revealed in "A Single Pale Rose" that Pink Diamond created Rose Quartz as an alias to escape her duties and protect the Earth, Steven admits to Amethyst in "What's Your Problem?" that he is lost and confused about the revelation. He is relieved that his mother never shattered anyone but is troubled by the extent of her deception and how it has hurt the Crystal Gems.

Greg Universe
"Anyway, what's up? Just needed to see your old man, pal around, learn some lessons about life?" Greg Universe is Steven's father. As seen in "Laser Light Cannon" and "Cat Fingers", they share a very strong father-son relationship, and Greg is always emotionally supportive. Although Greg does not live with Steven, they often hang out. In "House Guest", it is shown that Steven and his father used to live together, but when Steven grew older, he moved in with the Crystal Gems for them to teach him about "magical Gem stuff" - something his father can't do. However, even though Greg knows that Steven is safe in the Crystal Gems' care, he is still slightly apprehensive about Steven going on missions and getting involved in "Gem stuff", which he tries to avoid if Steven brings it up, although there are some instances in which he has joined the Gems in solving problems.

Unlike the Crystal Gems, Greg does not seem too concerned about Rose giving up her life as Steven inheriting her "Gem identity" - other than the latter getting Steven into situations that Greg does not approve of. As such he treats him much more like his own person, and Steven does not seem to feel any guilt towards Rose's "death" when he is with his father. This is probably because as a human, Greg is much more familiar and comfortable with the idea of offspring as well as death, concepts which are strange and unfamiliar to the asexual and nigh-immortal Gems.

As a result, Steven is very comfortable and relaxed whenever he is in the presence of his dad as he provides a link to the human world, away from "magical Gem stuff". He also looks to Greg for advice on life, Gem affairs, and the like. Greg is Steven's main go-to for help on regular human affairs, and Greg understands how to help Steven in ways the Gems can't, such as in "Steven's Birthday" when he takes baby Steven for a drive to calm him down, just as he'd done before, and in "Gemcation" when he comforts Steven over his fear that his friendship with Connie is ruined.

Pearl
"Well, I think you're pretty great." Pearl acts more like an overprotective mother (since he is Rose's child) to Steven. Pearl harbors mixed feelings for Steven deep down; while she cares deeply for Steven she also misses his mother very much, as they were very close to each other when she was still alive. However, she shows a deeper affection than most for Steven, admitting to watching Steven once he has fallen asleep. She sees much of his mother in him, as Steven becomes a constant reminder of Rose, which is a bittersweet sentiment to Pearl. These feelings come to the surface in "Rose's Scabbard" where the revelation that Rose had apparently kept secrets from Pearl, her closest friend and confidant, causes Pearl to break down mentally and run away from Steven and the other Crystal Gems. When Steven pursues her, she shows inward signs of resentment towards him and Lion, which culminates in her apparent inaction when Steven misses a jump and almost falls to his doom. The two reconcile at the end of the episode, but as revealed in "Joy Ride" Steven felt uncomfortable talking about his mother with the other Crystal Gems for a time, having believed that they partly blamed him for Rose's absence. However, Steven does still feel comfortable enough to talk to Pearl about his problems in "Historical Friction". He unknowingly comforts her in stating that flaws are important to everyone and asks her to tell the real story of William Dewey. During the play, he waves to her while she is encouraging him. When he learns that Pearls are made as servants on Homeworld, he declares that she is not common, but she is amazing and tries to be better than she already is as said in "Back to the Barn".

Amethyst
""Stop trying to be like Jasper. You're nothing like Jasper! You're like me! Because we're both not like anybody. And yeah, it sucks. But at least I've got you. And you've got me! So stop leaving me out of this." "Us worst Gems stick together, right?" "That's why we're the best."" Amethyst acts like an older sister to Steven, often joking around with him and joining him in his misadventures. Pearl often scolds Amethyst for being too reckless with Steven when she misleads him such as in "Cat Fingers", which Amethyst admits is probably accurate. Steven seems to acknowledge Amethyst's reckless nature, calling her out when she did not help him in "Joking Victim" and worrying about her safety in "An Indirect Kiss". However, Steven cares greatly about and loves her, Amethyst loves and cares about Steven as well but does not show it too much due to her tomboyish attitude. In "Reformed", Steven misses Amethyst once the Slinker poofs her, and he also liked her new forms as he found them funny.

Amethyst also tries to impress Steven because she wants him to like her. Steven secretly feels Amethyst blames him for his mother not being around. Amethyst is becoming more motherly as time passes. An indicator of this is in "Onion Friend" when Amethyst and Vidalia joke about kids. Additionally, Amethyst is becoming more protective of Steven, both in dangerous situations (such as grabbing Steven with her whip in "Friend Ship") and in general (such as when she lectures/scolds him about the dangers of stretching out his body in "Steven's Birthday"). In "Steven vs. Amethyst" Steven tries to convince Amethyst how great she is and tells her he understands about not being who you're supposed to be when he tells her he is not Rose Quartz, which shocks her. "Earthlings" highlights their bond as he explains that he is just like her, that they are not like anybody else as they are both different from normal Gems, and asks her to stop shutting him out, which leads them to fuse into Smoky Quartz. After the battle, Amethyst leans into Steven, showing their newfound closeness. "Know Your Fusion" shows that they are close enough to fuse into Smoky Quartz by grasping hands, not needing a fusion dance.

In "What's Your Problem?", Amethyst admits she is angry about Rose not admitting she was Pink Diamond, but doesn't want to dump all of her emotional baggage onto Steven, but rather shares her concerns for him. Steven later calls her the most mature Crystal Gem in that episode.

Garnet
"That's a lie. Your middle name is cutie pie." Garnet acts like a lenient and kind mother, always encouraging him and setting a good example. It is shown that Steven respects her as he always listens whenever she speaks. Steven usually asks Garnet for permission before anyone else, as shown in "Monster Buddies". As shown in the aforementioned episode, Garnet is usually open to letting Steven attempt things that Pearl may not, indicating that she has more trust in him than Pearl. Despite her stoic and somewhat distant nature, the two share an occasionally close and emotional relationship. She becomes emotional as Steven aged rapidly in "So Many Birthdays"; in "Future Vision" she shares her "future vision" to him- which she only does because she thinks he would understand and it would bring them closer. Immediately after Sapphire and Ruby's re-fusion in "Jail Break" Garnet acts a lot more emotional and loving towards Steven, indicative of the deep, true love that she has for him that her pre-regeneration self would not, or could not, express.

Ruby & Sapphire
"Oh Steven. We already love you." Not much is known about the relationship between Sapphire, Ruby, and Steven, other than they all care for each other. Since Garnet is a Fusion Gem of the two, their individual feelings for Steven are similar to Garnet's feelings for him. This is shown in "Keystone Motel", as they both apologize to Steven upon arguing in the diner, which had driven Steven to tears. Sapphire even goes so far as to cry herself, out of guilt. In "Hit the Diamond", Steven is quick to hug both the Gems when Garnet unfuses, but is distressed over the two ignoring the game to flirt with each other, leading him to give them a pep talk/scolding, which both of them listen to. This shows that both Ruby and Sapphire love and respect Steven enough to listen to him.

In "Three Gems and a Baby", it is revealed that Steven first saw Ruby and Sapphire when he was only a few months old. Garnet, who thought Steven was a fusion like herself, unfused to get him to do the same. Steven, confused by Garnet's sudden absence, started crying, causing the two to fuse back right after.

Connie Maheswaran
"Keep your hands off my Connie!" Connie is Steven's best friend. They first saw each other at a parade the year before they met. Steven was on a float for the car wash, and Connie was in the crowd; Steven noticed she dropped her glow bracelet and kept it in his freezer ever since, to make it last longer. In Connie's debut episode, "Bubble Buddies", he saves her from a falling rock by using his gemstone to summon his bubble. He is initially very awkward and nervous to talk to her, even more so once they are trapped in the bubble because he is trying to stay calm, but he is able to relax more once he gives Connie her glow bracelet. After defeating the Gem monster that is attracted to the glow of Connie's bracelet, Connie appears to be amazed by Steven, saying "He was incredible!" in reaction to everything that had happened.

Their friendship has grown, and presently they are very close friends. In "Lion 2: The Movie", they are shown casually hanging out. In "An Indirect Kiss", Steven and Connie are shown not to care about things such as sharing the same straw. In this episode, Steven discovers his healing powers, as he inadvertently fixes Connie's bad eyesight. He genuinely cares about Connie's safety and well-being as seen in "Winter Forecast", as well as in "Full Disclosure".

In "Alone Together", after they have a dance, they accidentally fuse to form Stevonnie. They are overjoyed by their ability to be fused and enjoy being Stevonnie, although it appears that they cannot control when they fuse. It seems to happen when they dance together while thinking about their feelings for each other. Connie, however, is terrified of the thought of her parents knowing about this or any of the magical things she does with Steven. It is for this reason that she lies to her parents about Steven in "Fusion Cuisine", saying that he had a traditional nuclear family. When he found out she lied, Steven feels hurt, believing that she was embarrassed by him. Fortunately, after she explains that she was simply scared of her parents not letting her see Steven again, he forgives her.

In "Sworn to the Sword", it is shown that Steven and Connie function extremely well in combat as a team, with Steven defending Connie with his shield and protective bubble while Connie attacks using her sword-fighting skills. Together, they manage to defeat multiple versions of Holo-Pearl, and their ability to work well as a team surprised Pearl initially. However, Pearl is able to defeat them after she overcame her initial surprise. After calming down, Pearl admits that they work well together.

In "Cry for Help", a picture of Connie can be seen in Steven's room. During "Steven's Birthday", he expresses the assumption that Connie will become president as an adult and worries that his stunted growth would make him the "First Boy" when that happens, implying that he wants to marry her. Steven still seems to become awkward whenever Connie is close to him as shown in "Steven's Birthday" when Connie lays her head on Steven's chest.

Along with their love for each other Steven and Connie share an equal partnership and friendship. "Beach City Drift" shows their partnership in that they can now fuse into Stevonnie at will and when they unfuse Connie shows Steven they are obsessed with Kevin. In "Gem Hunt", Steven follows Connie's lead while they are tracking the Gem. Both instances show that he relies on her intelligence and good sense.

In his own way, Steven is also shown to be close or equal to Connie in intelligence. He has been able to converse with her on equal footing since they first met and he listens to and absorbs everything she teaches him, showing that while Steven's intelligence is as deep as Connie's he lacks the breadth of her knowledge.

In the last episode of the 6th StevenBomb, "I Am My Mom", Steven comes to terms with his feelings for Connie and confesses his love to her as he is taken away to Homeworld. It is unknown whether he was referring to her specifically or everyone in general, but it's heavily implied that it was for her.

In "Lars' Head", after Steven finally returns to Earth, Steven tells Connie and the other Gems and Greg that he is back as Connie runs up to hug him along with the Gems and Greg.

However, in "Dewey Wins", Connie expresses that she feels betrayed that Steven gave himself up to Aquamarine in "I Am My Mom", instead of continuing to fight alongside Connie like he promised. Steven obliviously attempts to get her to look at the bright side of the situation, arguing that everything is fine since no one got permanently hurt. After a frustrated Connie leaves on an equally upset Lion and stops responding to Steven's texts afterward, Steven becomes afraid that she hates him now. In "Kevin Party", a few weeks later, Steven and Connie reunite at Kevin's party, and after overcoming their own tensions and Kevin's manipulations, the two finally talk to each other again. Connie apologizes for not texting Steven back and leaving him in the dark for so long, explaining that she couldn't figure out what to say, among other circumstances. Steven in turn apologizes for giving himself up and not taking Connie's feelings into account, and the two of them affirm that they are still "jam buds."

In "Lars of the Stars", Steven and Connie travel through Lion's mane to take a care package to Lars and find that he and the Gems known as the Off Colors are now a space crew trying to return to Earth. Steven reunites with Lars, introduces Connie to the Off Colors, and the two deliver the package to Lars. When Lars later has a breakdown after learning that Sadie is now in a band with Steven and the Cool Kids, and assumes that she is having such a good time to spite him for all the times he let her down, Steven and Connie set him straight; they tell him that Sadie does still care for him and is very worried for him, but she has to keep going in her life, just like Lars has to keep going in his life as he tries to get back to Earth. They finish by reminding Lars that he and Sadie are best friends and would never do anything hurt each other, fusing into Stevonnie in the process. They remain fused for the rest of the episode and all throughout the following episode "Jungle Moon", the latter of which goes over the course of at least several days as they work to survive until Lars can find them; this indicates that since the events of "Kevin Party", their bond has not only recovered, but is now stronger than ever. Steven has also stated in the podcast that since their reconciliation, Connie has been helping him cope with the recent events since he was on Homeworld.

In "Reunited", Connie participates in Ruby and Sapphire's wedding and fights alongside Steven and the other Crystal Gems. Later, when he is knocked out by Yellow Diamond, Connie frantically tries to wake him up, reminding him of their reconstituted promise to always be a team. Fortunately, Steven, who's consciousness is on an abstract astral plane is able to communicate with Connie, and tells her to watch his body while he tries to get through to Yellow and Blue Diamond. Following his success, in "Legs from Here to Homeworld", Connie travels to Homeworld with Steven, the original three Crystal Gems, and the two Diamonds, and expresses great concern when Steven is forcibly taken away by White Pearl to meet White Diamond.

Lion
"Blink if this means you love me!" Lion is Steven's "pet" whom he first met in "Steven's Lion" while the Crystal Gems were retrieving the Desert Glass. He has some connection with him, as Steven is the only one who can enter his pocket dimension. Lion, most of the time, does whatever he wants and often ignores or disobeys Steven. However, Lion is also seen to be caring towards Steven as well as being aware of Steven's needs, like when Lion kept lying on Steven's head to show Steven his pocket dimension where it contained, among other things, a video left by Rose Quartz for Steven, after he said he wanted to know more about her in "Lion 3: Straight to Video".

Their relationship slightly sours in "Dewey Wins", when Connie gives up in frustration after trying to make Steven understand how much he hurt her by surrendering to Homeworld and asks Lion to take her home. Lion shoots Steven a disapproving glare before leaving with her, showing that he shares her anger at Steven over his surrender, as well as him treating the situation as nothing, and ignoring her feelings about it. Over the next few weeks afterwards, Lion stays with Connie, presumably to give her comfort and companionship during her and Steven's estrangement, as well as teach Steven a hard lesson over his taking her and his other loved ones for granted; Connie later rides him to Steven's house in an attempt to reconcile in person after failing to do so over the phone, only to find that he'd gone on vacation. In "Kevin Party", Steven is seen putting up missing posters for Lion, indicating that he misses Lion very much. Steven later reunites with Lion and Connie at Kevin's party, and following his reconciliation with the latter, Lion forgives him as well, as he allows Steven to ride on his back again as they and Connie leave the party by his portal, and by "Lars of the Stars", he shown to once again be under Steven's care and on good terms with him.

In "Can't Go Back", Lion brings Steven to the moon base when the latter discovers the Barn on the moon. Later, Lion demonstrates his caring and protectiveness of Steven's wellbeing when he stops him from blindly running after Lapis after she opens the base's doors, and then nuzzles Steven in comfort when he ultimately fails to stop her from leaving.

Sadie Miller
Sadie is one of Steven's friends who, unlike her co-worker Lars, is friendly, considerate and affectionate towards Steven. In "Joking Victim", Steven helps Sadie by working at the Big Donut. Steven also helps Sadie to strengthen her relationship with Lars in "Island Adventure". Steven also filled Sadie's place in Beach-A-Palooza in "Sadie's Song", after realizing how he and her mother had ignored her feelings toward singing. Later he is shown playing his ukulele with her singing with a sad smile. This could hint he really is sorry and is trying to be more respectful to her desires.

Lars Barriga
"Lars... I'm afraid right now. I thought if I turned myself in, it'd fix everything, but... I don't want to do this, Lars. I just wanted to save everyone, but I couldn't even do that because look -- you're still here." In earlier episodes, Steven was very friendly towards Lars and was oblivious to the fact that he was annoyed by him, often believing it to be harmless jokes. In "Bubble Buddies", he calls Lars his "BFF" in while he openly makes fun of him. Steven looked up to Lars very much and wanted to be accepted by him, even once saying he did not mind suffering third-degree burns to receive a high five from him.

However, in "Lars and the Cool Kids", he is pushed to the limit, angered by Lars insulting Rose, and calls him a jerk, showing he does not hesitate to call out him on his bad behavior at times. They eventually find a way to connect, and Lars gets on better terms with Steven. Because of his tendency to help people, Steven also pushes Lars to his limits, almost unintentionally ruining his friendship with Sadie in "The New Lars" in an attempt to help him.

In "The Good Lars", Lars and Steven seemed to have developed a more open friendship, even taking his advice to bake the Ube cake, and asks when Steven even got so mature. In "Stuck Together" Steven is upset to find that Lars had ended up staying on Aquamarine and Topaz's ship and constantly tries to help him get off as a team effort.

Noticing his half-hearted efforts to cooperate, he is infuriated but finds out of his jealousy of always helping people. However, Steven lets him know that he was afraid as well, and they bond over the fact that they are not alone. This friendship further develops in "Off Colors" when they spend time in the abandoned Homeworld Kindergarten. When the Robonoids attack, Lars nearly has another panic attack, but Steven comforts him, saying that it was okay to be afraid. Having kept this in mind, Lars manages to save everyone at the cost of his life.

Steven is devastated by Lars' death and cries over him knowing he did not save him. However, when Steven revives him, Steven shows much more devotion and care to Lars, and he the same. When they find a potential way home, Steven does not want to leave Lars behind, but he is convinced, and instead of high fiving, they hug each other, showing how close they have become since the beginning as Lars allows Steven to return home.

Onion
Onion is Steven's friend whom he talks to in the episode "Bubble Buddies". Steven addresses Onion as if they are good friends. In "Onion Trade", Steven gives his favorite action figure to him as a gift, despite the fact that Onion had originally stolen it. When they are not together, Steven expresses some confusion as to who and what Onion is, being unsure if he is even human in "Marble Madness", and is sometimes made uncomfortable by him. In "Onion Friend", Steven and Amethyst stay at Onion's house for dinner. It is there that Onion shows Steven around his room, inviting him to feed his pet snake and show Steven his collection of G.U.Y.S. and G.A.L.S.; he later gives Explorer Gal to Steven as a token of their friendship. In "Onion Gang", Steven is introduced to Onion's Friends, and after they have to leave town due to summer ending, Steven comforts a sad Onion, saying that he'll always have good memories of the times they had together, and, until next summer, Steven says he has him.

Peedee Fryman
Peedee is Steven's friend whom he helped out in the episode "Frybo". Thanks to Steven, Peedee earned the respect of his father and did not have to wear the Frybo suit anymore. They have a generally professional relationship of customer and cook (despite Steven usually ordering off the menu) though still enjoy each other's conversation.

Lapis Lazuli
"Steven – is – a new friend!" Steven became friends with Lapis in "Mirror Gem" when he is given a mirror by Pearl, which turns out to not work. A little while later, Lapis begins to talk to Steven by replaying visions that the mirror has witnessed over the course of the day, and they become good friends, with Steven calling them "Beach Summer Fun Buddies", a nickname to which Lapis agrees. She wants to get out of the mirror and "tells" Steven how to do so. After she is free, she warns Steven not to trust the Crystal Gems and walks away. In "Ocean Gem", Steven is the one who insists on speaking to her and gets angry when she refuses to do so and hurts him and his friends. However, he understands Lapis' desperation to go home and heals her cracked gemstone, which, as a result, restores her eyes and wings. She thanks Steven before departing back to her home planet. In "The Message", Steven defends her and sings a song all about her and the previous events. When Lapis gives Steven the message, he is very concerned about her, as he was distraught by her unhappiness. In "Jail Break", Lapis fuses with Jasper, forming Malachite, as a way to save Steven. Later in "Chille Tid", while the Gems are searching for Malachite, Steven's motivation is to save her from her fate of being trapped with Jasper. He soon discovers he can communicate with her through his dreams. While talking to her, Lapis refuses his help, saying, "Just let me do this for you!" "Same Old World" expands on their relationship as Steven helps Lapis find a home on Earth. She easily carries him on her back and plays around with him in the air. "Barn Mates" expands things further as Steven tries to help Lapis and Peridot get along. "Alone at Sea" shows that Steven cares enough about Lapis to bring her on a trip on Greg's rental boat in order to help her get over her trauma and fear of the ocean because of her experience as Malachite.

In "Raising the Barn", Lapis offers Steven the chance to flee Earth with her and Peridot to remain safe from the Diamonds. Steven rejects the offer, but affirms that he won't try to talk her and Peridot out of it if they don't feel safe on Earth. However, in "Can't Go Back", Lapis admits to Steven that she misses Peridot and regrets leaving due to feeling so lonely. However, her uncertainty of Peridot's reaction and fear of the Diamonds prevents her from returning to Earth and after Steven has a vision of the latter, she leaves the moon to get as far away from Earth as possible, stating that she isn't like him.

However, in "Reunited", Lapis returns to help Steven and the Crystal Gems fight against Yellow and Blue Diamond, dropping the Barn on top of the latter. Steven is overjoyed to see her again and his joy increases when she officially declares herself a Crystal Gem. When she is later poofed in battle by Yellow Diamond, Steven expresses great concern for her.

Nephrite
Steven becomes friends with Nephrite in "Monster Buddies" when he accidentally pops the Gem bubble which Nephrite's gem is in. At first, she is wary of her surroundings, being scared by the presence of the rest of the Crystal Gems. By approaching her calmly and feeding her Chaaaaps, Steven managed to calm her down, and later train her. She is even willing to risk her life to save Steven from a falling icicle. Steven believes she is not a monster and that he can help heal her in the future.

In "Monster Reunion", Steven defended Nephrite from the Gems because they believed she would still be unstable, despite Steven healing her; however, she shows a great deal of appreciation after Steven reunites her with her crew.

In "Legs From Here to Homeworld", Steven heals Nephrite along with Yellow and Blue Diamond, but she immediately reverts back to her corrupted state once they take their hands off her.

Peridot
"Peridot: Do you have any last words?! I love you, Peridot. Peridot: Wow, thanks." Steven did not really know how to feel about Peridot when they first met, but he seems to want to befriend her in "Marble Madness", approaching her without fear and even trying to have a friendly conversation with her. Of course, this does not go as well as he hopes and he almost gets crushed by her. Despite this, he still believes she can be good and even said that maybe if she sees how nice humans are she might not want to hurt anyone. In "Keeping It Together", Steven is the first to find her. He quietly waits for her to finish her report instead of alerting the others until she notices him. When Peridot asks if the others are with him, Steven tries to lie by shaking his head "no" until he nods "yes" with an apologetic shrug. During the chase, Steven seems to care about her when he asks if she is okay after falling off the wall. In "Friend Ship", Steven is kind to Peridot by wishing her a good morning and weekend. During the battle, instead of being cold and ruthless to her as she does to him and the rest of the Crystal Gems, he teases her instead.

In "Catch and Release", Steven is worried and wants to know what Peridot is trying to say at the Galaxy Warp, and chooses to pop her bubbled gemstone and release her. After he finds out she is short, he calls her cute and teases her, leading to Peridot slapping him in some playful way. After offering her the foot of her limb enhancer suit, Steven becomes the only person Peridot allows into the bathroom after she locks herself in. Peridot seems to take the gesture extremely well and is on much better terms with Steven by the end of the episode. In "When It Rains", Steven comforts Peridot and explains the process of rain and says it is harmless. After Peridot steps out in the rain, she claims she has made up her mind about telling information about the Cluster, leading to Steven giving permission to go to the Prime Kindergarten only if they hold hands the entire way, due to Steven having to watch over her. Their friendship has been getting stronger, and they are trusting each other more, although in "Too Far", he is visibly upset (or embarrassed) at her calling him a "hybrid abomination".

Returning from a mission to the Moon base, Steven notices a small object in Peridot's hand. Steven asks Peridot into a truck to discuss something. Tricking Peridot, he locks her in the truck to question her about the object. Peridot reveals that is a direct communication line to the Diamonds. Shocked at her apparent betrayal, Steven leaves her locked in the truck and tells the other Gems of what occurred, very upset at Peridot for having learned nothing. Peridot soon escapes and activates her robot to retrieve the communicator.

Once she obtains it after a fight with the Crystal Gems, she opens an interface to Yellow Diamond.

Peridot reports the progress of her mission to her, omitting the interactions of the Crystal Gems. She then pleads a case to Yellow Diamond to stop the Cluster and spare the Earth, which Yellow Diamond spitefully denies. She then orders Peridot to let the Cluster be and report for her next mission. Outraged, Peridot refuses to follow Yellow Diamond's commands and calls her a "clod", marking her a traitor. Steven exclaims that her actions against Homeworld have made her an official Crystal Gem.

When the Cluster was beginning to emerge Steven and Peridot go down in the drill to destroy it. During a brief moment when the possibility of death is very real, Steven expresses no qualms about dying in Peridot's company. During this time he also says his "last words", which are "I love you, Peridot" to her, showing his care for her.

Sardonyx
Steven finds Sardonyx funny and articulated as shown in "Cry for Help". Sardonyx has taken a liking to Steven too, being incredibly excited when meeting him for the first time.

Opal
"♪ All I wanna do is see you turn into a giant woman. ♪" Steven first meets Opal in "Giant Woman". He becomes very eager to meet the fusion when Amethyst and Pearl reveal the information and the concept of fusion to him. First meeting her after she rescues him and Steven Jr. from Big Bird, he is somewhat intimidated. However, she shows her affection for him by singing his song back to him, which makes him delighted.

Sugilite
Steven first meets Sugilite when he and the Crystal Gems went on a mission to destroy the Communication Hub. Impressed by her immense size and strength, she inspires Steven to become stronger. Sugilite, in turn, enjoys having an audience to her show-off actions. Steven quickly realizes how destructive Sugilite is, but does not seem to have any real issues with her and even looks forward to seeing her destroy the Communication Hub again, despite her attempts to destroy Pearl for having left her behind.

Alexandrite
Because Alexandrite typically only forms in dire situations, Steven has rarely interacted with the fusion. She has been seen speaking directly to Steven only once, and this was in an effort to protect him and Connie. Like her constituent Gems, Alexandrite cares deeply for Steven, willing to act as his mother in "Fusion Cuisine" and forming to protect him in "I Am My Mom" and "Reunited". Steven returns this sentiment, as shown by his efforts to assist Alexandrite in her fight against Malachite in "Super Watermelon Island".

Jasper
"Jasper... I-I tried to help you, but you wouldn't listen! I... I told you to stop, I had no choice!" When Jasper first arrives on Earth with Peridot and Lapis, Steven seems immediately aware that she could not be reasoned with or befriended. At first, he is unnerved by her violent talk and intimidating stature, and since then he has been terrified of her. Jasper thinks Steven is in fact just Rose Quartz hidden in a weak constitution, possibly after regeneration. In "Chille Tid", Steven is horrified of Jasper, and Jasper immediately attempts to attack him in an incoherent fury. In "Super Watermelon Island" however, Steven calls out to Jasper as she falls into a crack created by the Cluster, showing that he values her life despite their animosity. This is shown again as he attempted to heal Jasper when she became corrupted in "Earthlings". During this time, Steven finally told her that he is not Rose and gave her his real name but she still called Rose before she was corrupted. In "Mindful Education", it is revealed that Steven harbors intense emotional baggage for being unable to help her, Jasper mid-corruption manifesting in one of Stevonnie's hallucinations as a result.

Kevin
In "Beach City Drift", it reveals that his negative experience with Kevin in "Alone Together" as Stevonnie carried over to Steven full-force, being one of the few characters in the series Steven possesses hostility towards. He expresses a strong, enraged demeanor alien to Steven during and after a re-encounter with him at his dad's car wash, and is in a sour mood for the rest of the day. He even fuses with Connie and races him in hopes of rubbing it in his face. After realizing his obsession, he and Connie manage to let go of their anger towards him.

In "Kevin Party", Kevin invites Steven and Connie to his party in the hopes that they can make it an event that everyone will remember by fusing into Stevonnie. Unknown to him at the time, the two had been estranged for the past few weeks over Steven's surrender to Homeworld, and both only accept the invitation in the hopes of seeing each other again and working things out. However, upon seeing each other at the party, tension and uncertainty between them (due to Steven believing that Connie's new look was a sign that she had decided to move on from him, and Connie presumably being uncertain of what Steven thinks of her after unintentionally leaving him completely in the dark during the duration of their estrangement) prevent them from reconciling immediately. When Kevin learns of the situation, he, misinterpreting that Steven and Connie were a couple, attempts to get them back together so they can fuse, convincing an emotionally vulnerable and desperate Steven to play it cool and act like life is going well for him without Connie, so that she'll be desperate enough come to him. The advice, however, backfires, instead agitating Connie to the point where she believes that Steven has given up on making amends with her after being unintentionally ignored for so long, and has decided not only to permanently cut her from his life, but to also replace her with Kevin as his best friend, and nearly leaves distraught at this. After Steven stops her from leaving, and the two finally reconcile, Kevin attempts to get them to fuse, but they instead decide to take their leave on Lion, though not before thanking Kevin for his help and complimenting him on the party, much to his anger.

Bismuth
""I'm going to tell them! I'm gonna tell them everything." "Heheheheh... Then you really are better than her."" First meeting Bismuth in the episode of the same name, Steven is quick to respond warmly, showing admiration towards her tales of past battles and laughing indulgently at her jokes. He is also quick to open up to her about his feelings towards his mother and remarks that he is glad she is with them. Upon refusing to resort to the use of the Breaking Point, he continues his attempts to reason with her and upon being forced to destroy her physical form, shows his respect for her by promising to tell everyone what happened, giving her closure before poofing. In "Mindful Education", it is revealed that Steven harbors intense emotional baggage for defending himself against her and impaling her with Rose's sword, with Bismuth manifesting in one of Stevonnie's hallucinations as a result.

In "Made of Honor", Steven and Bismuth both reconcile after Steven frees her from her bubble permanently. She even went as far as to believe that Steven was the new leader of the Crystal Gems, despite the latter denying it.

In "Legs From Here to Homeworld", Bismuth gives Steven some sound advice as he departs for Homeworld.

Aquamarine
"Huh. Nice try. But it's hopeless, my dad. I can't go back to Homeworld without getting what the Diamonds want." Steven first meets Aquamarine while looking for some of his friends who have gone missing. He hears her ask "Are you my dad?" When he sees her, she appears very childlike, but he is at first shocked, seeing that she is a Gem, most likely from Homeworld. She asks if he is "my dad" again, he says no, and she flies off. Connie finds her standing in a tree, and tells her to come down, saying that they can help her, but Steven tells her to be careful. After capturing Connie, Steven commands her and Topaz to let his friends go, to which Aquamarine uses her wand to hurl Steven towards a tree.

In "I Am My Mom", Steven and the Crystal Gems confront Aquamarine and Topaz at Funland. Aquamarine reveals that the list of humans came from "a Steven" in a report from Peridot 5XG. After the Gems fail to fight Aquamarine and Topaz, Steven turns himself in as "my dad". Aquamarine says she's skeptical of how "a Steven" could also be a "my dad", but she accepts it because she wants to leave. When he tries to escape, Aquamarine freezes all of them in her wand's tractor beam. After thinking for a while, Steven tells Aquamarine that he is not "my dad", which frustrates her, but Rose Quartz, which then shocks Aquamarine.

In "Stuck Together", Aquamarine marvels at the fact that she captured "Rose Quartz", and that she handed herself in. After Topaz reveals that Lars is still on the ship, Steven tells Aquamarine the deal is off, which only results in Aquamarine taunting him, even pointing at her gem and saying "Look, I'm so moved I'm crying", and then laughs at him. Aquamarine says she'll let the Diamonds know about her prisoner, and then asks "Rose" how she looks, to which Steven replies "Awful, small, and mean!". Aquamarine takes it humorously, asking rhetorically if that is how "Rose" flattered so many Gems to join the Rebellion. After trying to escape, Topaz and Steven try to reason with her, with Steven saying that she doesn't actually want to hurt them and that she just acts mean because she's afraid to admit she's weak. Aquamarine reacts to this by looking visibly annoyed.

Blue Diamond
"I've been seeing through her eyes. I've been crying her tears!" While not having interacted before at the time, Steven has some form of emotional link with Blue Diamond. From across the world, Steven is involuntarily able to see through Blue Diamond's eyes and cry her tears through his dreams. He also cries Blue Diamond's tears when he is near her. He initially feels sorry for her as she and Greg talk in "Steven's Dream" for everything that has happened to her, including the shattering of Pink Diamond which has caused Blue Diamond a considerable amount of pain. Blue Diamond is not currently aware of the link that she and Steven share.

In "The Trial", it is shown that although Blue Diamond wants Rose Quartz to suffer for shattering Pink Diamond, she also wants Steven to present his case before his sentence. When it is indicated that Rose Quartz may not be responsible for Pink Diamond's death, Blue Diamond showed shock at the accusation that a Diamond was likely responsible.

In "Reunited", it is revealed that he views Blue Diamond as family due to his mother being Pink Diamond. During the aftermath, she shows a genuine display of affection towards him by nuzzling him and hugging him. She also supports his decision to cure the Corrupted Gems and expresses concern for him when he is brought to White Diamond.

In "Familiar", Blue Diamond acts warmly towards Steven whom she believes to be Pink. Steven jokes around with Blue and even says that the two should spend more time together. Steven knows that Blue and Yellow Diamond are dictators but in the song "Familiar" acknowledges the two love him which is why he hopes to change their authoritarian ways.

Yellow Diamond
"I'm sure your memories are in there somewhere, Pink." In the episode "The Trial", Yellow Diamond sees Steven as abominable to the point that she wanted to execute him just "for looking like that." Other than this connection, Yellow Diamond sees him as Rose Quartz by Steven's choice, and considering Rose's history, Yellow Diamond is furious with Steven's existence and pushes toward his execution as much as possible, only to be stopped by Blue Diamond.

However, after learning that Rose was Pink Diamond, Yellow begins to show genuine concern for him. While she still believes him to be Pink, she is willing to assist him in curing corruption and enlisting White Diamond's help.

In "Reunited", it is revealed that he views Yellow Diamond as family due to his mother being Pink Diamond.

In "Familiar", Yellow Diamond and Steven speak briefly about how to convince White Diamond to come to Earth so they can heal the corrupted Gems. Yellow states that the two and a half words Steven said to White is a new record, implying that White almost never speaks to anyone. Yellow complains to Steven that it is unfair how he gets to see White Diamond because he has one failed colony, while she has hundreds of successful ones. Steven suggests to Yellow that she should try failing which Yellow responds by laughing hysterically. The fact that Yellow rarely smiles, let alone laughs, shows how comfortable she is around "Pink" (Steven).

White Diamond
"Should I have brought a gift for White Diamond? We are dropping in unexpectedly, and... I want to make a good first impression. Her help will mean everything for the Corrupted Gems." From what Pearl and the other Diamonds have told him, and from White's reaction to his arrival on Homeworld, Steven appears uneasy and nervous toward White Diamond during their first meeting in "Legs From Here to Homeworld".

Pebbles
Steven is friendly toward his Pebbles, finding their antics amusing and appreciating what they do for him.

Trivia

 * Steven's name and appearance are based on Rebecca Sugar's brother, Steven Sugar, who is a background artist for the show.
 * Steven's birthday is August 15, the same day Steven Sugar was born. Coincidentally, this means that Steven Universe's birthstone is peridot, who is one of his closest friends.
 * On a similar note, Steven's name if he were a girl, Nora, was a name almost given to Rebecca before she was born.
 * When viewed from the back, the bumps of Steven's hair form a rose shape, though this is more visible on the Funko Pop! figurines than in the show.
 * In the transition from the pilot to the series, Steven underwent only one significant change: the removal of the gold ring around his gemstone.
 * Steven is home-schooled by the Gems. According to the comic Steven Universe: Too Cool for School, Pearl and Garnet's education for Steven is so effective that Steven gets a perfect score on a conventional human school's standardized test, despite being there just one day. Temple Door Steven.png
 * In "Together Breakfast", he had a phone that resembles an iPhone, but Garnet snatched it from him to destroy it after he took a picture of the Evil Spirit Scroll.
 * However, as of "House Guest", a new phone can be seen on his nightstand and again in "Full Disclosure" when he uses it.
 * Steven is a musical prodigy.
 * Steven was taught how to play the ukulele when he was only a toddler, as shown in the Extended Intro.
 * In "Steven and the Stevens", it is shown that Steven does play not only the ukulele, but also the guitar, bass, and drums.
 * He even plays the piano in "Mr. Greg".
 * He also has perfect pitch.
 * This ability is shown explicitly in "It Could've Been Great".
 * His performance of "Let's Only Think About Love" in "Reunited" shows he can sing falsetto.
 * It was revealed in "Monster Buddies" that Steven keeps a framed picture of Pearl on the side of his fridge. However, it was destroyed by the Centipeetle Mother.
 * Steven seemingly can breathe in space, as shown in "Ocean Gem" when Lapis Lazuli confronts him at the top of her water tower, even though he has to hold his breath in Lion's Dimension in "Lion 3: Straight to Video" and had to have a bubble around him to breathe in space in "Bubbled".
 * However, this could simply be a script error.
 * It is also possible that Steven simply has a lower oxygen requirement than a normal human would, as he can survive in low-oxygen environments such as the edge of Earth's atmosphere but cannot survive with a complete lack of oxygen such as Lion's Dimension or the vacuum of space.
 * In "Warp Tour", Steven is revealed to be allergic to pollen.Steven GTTCG Page.png.]]
 * Steven has successfully fused with a human (Connie), thus forming the first hybrid fusion, Stevonnie.
 * This is because of his half-Gem, half-human biology allowing him to fuse with humans.
 * In "House Guest", a Sailor Moon manga book can be seen on Steven's nightstand.
 * Steven's voice noticeably matures throughout the series, especially noticeable when compared to the earliest episodes to the latest.
 * It is stated by Ian Jones-Quartey that Rose shapeshifted a womb for Steven to be born from.
 * It is revealed in "Story for Steven" that Steven's T-shirt is one of his dad's old T-shirts he made in his musical career.
 * Steven has teddy bears, such as Master of Ceremonies Bear-Bear and Sir Bearington.
 * Steven seems to like drawing, as is shown in the episodes "Tiger Millionaire" when he drew the poster of Purple Puma and Tiger Millionaire, "Shirt Club" when he drew Greg, "Open Book" when he drew a picture of Lisa and Archimicarus from The Spirit Morph Saga, when he drew the locations map in Attack the Light, when he drew Lapis Lazuli and Peridot holding hands on an apology card in "Barn Mates", and when he was drawing the poster for Sadie Killer and the Suspects in "The Big Show".
 * His style is considered crude by many characters and is a recurring running gag throughout the series.
 * As shown in "Lion 2: The Movie", Steven is revealed to be ticklish.
 * According to an interview with Rebecca Sugar in 2015, the Gem that Steven knows the least about is Pearl at that point in the show.
 * Steven owns a few video game systems, including what appears to be a Nintendo 64, a Nintendo GameCube, and a Nintendo Game Boy. He also owns what appear to be copies of The Legend of Zelda: Wind Waker and Animal Crossing. He is also shown playing a fictional game, Golf Quest Mini, on his N64.
 * Steven is referenced in another Cartoon Network series, Uncle Grandpa, twice; first in the episode "Haunted RV", as a kid has a costume that resembles Steven's outfit, and second in "Pizza Eve", where he and the other Crystal Gems had a cameo, Steven himself even having a short line.
 * Steven sometimes refers to himself in the third person. This is possibly a riff on the "Third-Person Person" trope. This is most commonly used by young characters in media to sound cute or endearing.
 * Joe Johnston revealed on his Tumblr that Steven is his favorite character from the show.
 * Since Steven's biological age can be controlled by his state of mind, it is possible that Steven could live forever just like the other Crystal Gems if he learned how to control this ability.
 * Steven has been shown to be prone to motion sickness, particularly when quickly spinning.
 * As seen in "Catch and Release", Steven polishes his gemstone.
 * In "Say Uncle", Uncle Grandpa told Steven that he should polish his gemstone at least twice a year. In real life, rose quartzes don't need to be polished, while diamonds require professional cleaning twice a year, likely making Uncle Grandpa's line foreshadowing to the reveal in "A Single Pale Rose".
 * Throughout the show, Steven is shown to have impressive cooking skills. He is shown to have cooked various complicated dishes like the together breakfast in "Together Breakfast" and his salmon sandwich in "Onion Friend", and is generally seen cooking alone. He was even able to create fries and pizza bagels that surpass Kofi Pizza and Mr. Fryman's own products, forcing them to beg him not to make them for profit out of fear for their own livelihoods. This is possibly out of necessity; since the Gems do not require food (nor does any of it have to actually be edible in Amethyst's case), Steven had to learn how to cook on his own.
 * Steven has shown with both Connie and Amethyst that he does not need to dance to fuse, only requiring physical contact and an emotional connection to his partner.
 * So far, all of his known fusions use "they/them" pronouns. This is due to the fact that Steven has only fused with either a Gem, whom uses "she/her" pronouns, or Connie, a human female.
 * It is revealed in "Gem Heist" that Steven hates loincloths.
 * On the Mohs Hardness Scale, Diamonds are the hardest material. This is probably the reason behind Steven's enhanced durability and strength.
 * It is shown in "Gem Heist" that Steven can speak at least a little bit of Spanish.
 * According to the episode "Lion 4: Alternate Ending", if Steven had been born a girl, Greg and Rose were going to name her "Nora".
 * Steven is fused as Stevonnie for the entirety of "Jungle Moon", making it the first and only episode where he is absent. However, he is mentioned.
 * According to him, his favorite character from Crying Breakfast Friends is Egg: "because he has a lot of emotional scenes, but he's also got this really good redemption arc thing going on in the storyline and I've been following that a lot lately."
 * As seen in "Reunited", Steven has the power to officiate weddings in the state of Delmarva, most likely granted to him by Mayor Nanefua.
