|This article is about the navel gem Ruby. You may be looking for another Ruby.|
I could have done that. But then I would never have gotten to see the look on your face when you were tricked by your favorite little Ruby!
|—"Room for Ruby"|
Ruby, nicknamed "Navy" by Steven, is a Homeworld Gem who made her debut in "Hit the Diamond". She and the other Ruby troops were sent to Earth by Yellow Diamond to locate Jasper. After the Crystal Gems repeatedly thwarted "Navy" and her squad and stole their Roaming Eye ship, "Navy" infiltrated the Crystal Gems and stole the Roaming Eye back in "Room for Ruby".
Her gemstone is where the navel of a human would be, hence her name. Her outfit features a backless, maroon shawl-like top on her torso that opens around her solar plexus, and has a yellow diamond on the collar. She also wears dark brown shorts and pointed maroon boots similar to the other Rubies. She has more of a cherry complexion and has dark burgundy square-shaped hair.
She is part of the Ruby troops sent by Yellow Diamond and appears to be way more gleeful and sensual than the other Rubies of the troop. She is soft-spoken, amused by the Earth's details, expresses constant satisfaction, and dramatic in her mannerisms. She is also very flustered. When put on the spot she can get nervous to the point of nearly breaking down into tears.
Despite her cheery disposition, "Navy" also has a more sinister, sadistic, unhinged and manipulative side to her. In "Room for Ruby", "Navy" tricks the Crystal Gems by exaggerating her usual innocent personality. Once the Crystal Gems do not see her as a threat, lower their guard and take her in, "Navy" steals the Roaming Eye ship. When Steven points out that she could have simply stolen the ship in the first place, "Navy" gleefully replies that she wanted to see the look on Steven's face when she betrayed him.
"Navy" arrives on Earth with the other Rubies prepared to search for Jasper. They notice a nearby barn and decide to search it. Steven fools them, however, convincing them that they need to win a game of baseball before they can check the barn. The Ruby squad and the Crystal Gem Ruby constitute the Ruby team. They face off against the "human" team: Steven, Pearl, Amethyst, Lapis Lazuli, and Sapphire. "Doc" plays as the pitcher for the Rubies. They take the lead in the top of the ninth, but ultimately lose when Sapphire hits a two-run home run in the second half of the inning. When Sapphire reaches the home plate, she accidentally fuses with Ruby, revealing themselves to be Gems. The Homeworld Rubies realize they have been deceived and fuse together. Peridot runs out of the barn to help the other Crystal Gems. Upon learning that she was assigned to the Earth mission, the Ruby fusion demands that Peridot tells her where Jasper is. Steven tells her that Jasper is on Neptune, convincing the Rubies and prompting them to defuse. They board their Roaming Eye and head to Neptune.
After searching all of Neptune and the other planets in the solar system, they return to earth to look for Jasper again. After arriving, the Rubies are imprisoned in water bubbles by Lapis.
The Rubies are released from their water bubbles and questioned by Steven. After failed attempts at questioning "Leggy" and "Army", Steven tries to talk to "Navy", she tries to explain but suddenly gets too nervous to continue her explanation. The Rubies are tricked again, however, when they take Amethyst for Jasper after she had shape-shifted into the Homeworld Gem. Amethyst convinces the Rubies to allow her to stay on Earth with the pretext of keeping the Crystal Gems prisoner. Using the Roaming Eye, the Rubies and the Crystal Gems travel to the Moon Base after "Doc" tells Amethyst that she will need to file a report to Yellow Diamond. At the base, they discover the main panel destroyed and the Diamond Communicator missing. After Amethyst gives "Eyeball" the task of filing the report for her back on Homeworld, the Rubies board the Roaming Eye and prepare to leave. "Doc" exits the ship to offer Amethyst a ride back to Earth and sees her in her normal form. With her disguise revealed, "Doc" orders the other Rubies to assemble, and they fuse to fight the Crystal Gems. After Steven opens the airlock, Sardonyx forces the Ruby fusion to un-fuse, and the Rubies are sucked out into the vacuum of space.
When the Gems and Steven use the Roaming Eye to rescue Greg from Pink Diamond's Zoo, "Navy" is seen trying to grab onto "Army" before the two slam into the windshield of the ship, and then roll off.
"Navy" crash lands on Earth and immediately acts innocent to Steven and Garnet, telling them that she does not want to go back to Homeworld because the other Rubies are mean to her and that she wants to stay on Earth where she can be herself. Throughout the episode, "Navy" has a very exaggerated personality, acting as she is amazed by every little thing on Earth. Lapis does not trust her and is also distraught over how "Navy" has adjusted to Earth so quickly, and it took her (Lapis) a while to get used to it. Lapis apologizes to "Navy", and she agrees to show Steven, Peridot, and Lapis how the Roaming Eye ship works. However, she had Steven push a button that would send the three of them out of the ship. "Navy"'s reason for this is that she wanted to see the look on their faces when their favorite Ruby betrayed them. She drops the three of them into the ocean, and promptly blasts off into space, laughing all the way.
Post-"Room for Ruby"
"Navy" presumably rescued "Eyeball" from space with the Roaming Eye, as "Eyeball" appears on Homeworld in "The Trial"; it can also be assumed she exposed the Crystal Gems' continued existence to the Diamonds, as Blue Diamond later dispatched Aquamarine and Topaz to collect more humans for the human zoo. It is unknown whether "Navy" also rescued the rest of their squad.
"Navy"'s sentiments towards Era 3 are left undisclosed; whether she came to accept Steven and Homeworld's reforms, or remains an enemy of the Crystal Gems (similarly to "Eyeball" and Aquamarine) is never revealed.
"Navy" possesses standard Gem abilities.
- Piloting: As shown in "Room for Ruby", "Navy" is an expert pilot, being able to maneuver the Roaming Eye with ease. She shares this skill with Pearl, Peridot, and "Doc".
- When fused with "Doc", "Eyeball", "Army", and "Leggy", they form "Giant Ruby".

"Navy" is a member of a team of Rubies that is sent out to locate Jasper and bring her home. Out of the group, she seems the nicest and her merry way of approaching everything seems to be accepted by them, as they do not call her out to act more serious.
When Ruby is not in the know about what happened "last time", when they did not search a place through and through, she playfully chides her, stating that she is "so forgetful" (even though not knowing her). This could demonstrate her friendliness towards new members of the group, as saying it like this includes Ruby into their past activities. She also approaches the new member of the group, "Leggy", excitedly telling her that she thinks Amethyst (who was shape-shifted into Jasper at the time) is "so funny and strong". In "Back to the Moon" she demonstrates to have more closeness towards "Army" by jumping on her head and holding it when they were both excited about seeing "Jasper", trying to hold to each other in "Adventures in Light Distortion" and being depicted by walking together with her in Fusion for Beginners and Experts.
She also shows a strong camaraderie for her comrades as seen in "Room for Ruby". She lied to the Crystal Gems about wanting to join the group just to steal back the Roaming Eye and betray them.
Compared to the other members of her squad, she displays a distinct level of devious intelligence, using her cheerful disposition and appearance of naïvety to trick the Crystal Gems.
"Navy" makes up the right arm of their fusion and seems the most stoked, but is also the least serious about fusing: When holding onto her team members, she closes her eyes proudly and strikes a pose.
"Navy", like the rest of the Homeworld Gems, expresses some dislike for the Crystal Gems, due to being repeatedly tricked by them and being enemies. However, she is, along with "Leggy", the member with the least animosity towards them, as she seems friendly and content about almost everything. When trying to talk in front of them, she gets stage fright and retreats because she finds the situation embarrassing, seemingly not wanting to disappoint them. She was not above tricking them herself in revenge, however.
In "Back to the Moon", Amethyst shapeshifts into Jasper to fool the Rubies again. Amethyst, both acting like she believes Jasper would and being her usual joker self, makes the Rubies comfortable in her presence. They sympathize with her story of keeping the Crystal Gems prisoner, crying and clapping because of her apparent devotion. They also joke alongside with her when she pokes fun at Pearl for being talkative, kicks some earth rocks to demonstrate her animosity towards the planet or gives the Crystal Gems the silly nickname "Crystal Germs.".
"Navy" especially seems smitten with her, as she runs up to "Leggy" and tells her that she thinks "Jasper is so funny and strong", this being a direct reaction to Amethyst's funny jokes.
She first formally meets Peridot in "Room for Ruby", and there seem to be no negative feelings between them as they both enjoy rolling in the dirt together. "Navy" is shown to, in truth, not to care for her, ejecting her from the ship during her betrayal, just to see her face as she did so. Peridot does not hear her speech during the betrayal and assumes "Navy" was simply showing the ocean to them. She does not feel any negative emotions towards "Navy" because of this.
Lapis tried to teach "Navy" about Earth and became increasingly frustrated by "Navy"'s quick understanding and love for all things on Earth. She is angered by her betrayal but ends up laughing to herself after realizing that she was right about it being truly impossible for someone to have no hard feelings and adapt to a new place so easily.
"Navy" pretended to act sad after her hurting her feelings but still betrayed her at the end for the sole reason of seeing her face as she betrayed them.
"Navy" does not interact with Steven much in most of her episodes but bonds with him in "Room for Ruby". The two seem to enjoy many things together and love Earth. In reality she is shown to not care for him, ejecting him from the Roaming Eye just to see his face as she did so.
- The ruby is closely associated with aspects such as vitality, life, passion, and fire, all of which can be symbolically linked to the color red.
|"Navy" has a red stone in the umbilical region of her abdomen. It has a square facet, the front and back are symmetrical, and it has a light pink ring around it, which is usually hidden inside her body, except when she is regenerating. It is a decahedron, specifically a truncated tetragonal bipyramid.|
