I forgot how great it feels to be me!
Sugilite is a colossal and menacing fusion with a stocky, bulky build and four arms (each pair seeming to share a shoulder joint). She features four, medium-lilac eyes located under a strong brow and a fifth one above it. Her mouth is twisted into a grin and filled with sharp, pointed teeth. She has a giant plume of spiky, dark purple-black hair kept in an untamed style similar to Amethyst's, but messier. Her skin color is lavender, like Amethyst's. In close-ups of her, she appears to have purple fingernails painted to appear as gemstones themselves.
Her gemstones are located on her chest, and on the palms of the hands of her upper arms. As of Amethyst and Garnet's regenerations, Sugilite's palm gemstones have been relocated.
She has fuchsia skin, wears a ripped, dark purple, black and burgundy bodysuit similar to Garnet's, and a lilac visor covering her lower eyes. She has four arms which are connected at her sleeves. Her bodysuit has tears in it that are similar to Amethyst's.
Her top is now split into two colors: violet and a darker purple. Her leggings are also no longer ripped, but feature star-shaped patches, much like Amethyst's current leggings, with the left one colored black and the right one colored dark-violet. Her hair became longer, gaining an even darker shade of purplish-black, and her skin takes on a more lavender/violet hue, although this could be due to the lighting. Ruby and Sapphire's gemstones are now located on her lower pair of arms with the spiral gloves, which is due to Amethyst's outfit palette essentially being reversed in her latest regeneration.
I can be brash, and you can be reckless, and we can both get carried away.
|—Garnet, Cry for Help|
Garnet states in Guide to the Crystal Gems that Amethyst's lack of inhibition and her own raw power makes Sugilite so fun to be, causing the fusion to be hard to separate.
Despite her destructive nature, she does seem to retain an attachment to Steven, refraining from marking him as a direct target during her rampages. Ironically, she inadvertently causes a chunk of debris to fly off at Pearl, who deflects it and hits Steven in the face. Sugilite appears to want to impress Steven with her strength, asking if he wanted "to see something cool?" when summoning Garnet's gauntlets and Amethyst's whip to form her flail.
Sugilite first formed in this episode. At the Communication Hub, Garnet remarks they need Sugilite to destroy the hub, asking Amethyst to fuse with her, though Pearl greatly objects, speaking about Sugilite's unstability and how she should fuse with Pearl instead to be careful. Ecstatic, Amethyst and Garnet complete the fusion dance and Sugilite appears. She asks Steven if he wants to see something cool, to which he replies yes to, prompting Sugilite to combine Garnet's gauntlets and Amethyst's whip into her flail. She begins to destroy the hub with her flail, but when a rock hits Steven, Pearl and Steven warp back to the Temple, leaving Sugilite back at the communication hub, promptly before a rock lands on the warp pad, breaking it and stranding Sugilite. The next morning, Sugilite, having walked back to the beach from the Communication Hub, arrives at the Temple, breaking Greg and Steven's gym. Pearl says Garnet and Amethyst are losing themselves in the fusion, to which Sugilite replies that she is herself and she is sick of being separated. A fight between Sugilite and Pearl ensues, though despite Sugilite's size and sheer strength, Pearl is able to outsmart her. Sugilite chases Pearl up a hill,and Pearl uses her spear to break the ground under her feet. Sugilite falls to the ground, and her flail lands atop her head, causing her to unfuse.
Sugilite next appears in a non-speaking role. In this episode, Sugilite has a new form due to Amethyst's reformation in the episode "Reformed" and Garnet's (Ruby and Sapphire's) regeneration in the episode "Jail Break". After Garnet finds out Pearl had been repeatedly fixing the Communication Hub in order to fuse with Garnet into Sardonyx, Garnet demands Amethyst fuse with her in order to destroy the hub. They fuse and Sugilite appears, using a wind-up punch and destroying the Communication Hub in one hit before supposedly unfusing, though it can be assumed no brute force was required to get Sugilite to unfuse, as the next shot shows Garnet and Amethyst separated and back at the Temple.
You like that, little man?
|—Sugilite to Steven.|
You think you're something?! You... ain't... nothing!
|—Sugilite to Pearl.|
Is that all you got? You think that's enough to beat–
|—Sugilite on her fighting abilities.|
Sugilite possesses standard Gem abilities.
Being a juggernaut-style fighter, Sugilite uses her sheer strength to smash objects and size to overpower and crush any opponent(s).
Though not as acrobatic and nimble as Opal, Sugilite makes up for it by sheer size - her long legs allow her to cover much ground quickly and leap long distances. Sugilite also has no known weaknesses except her recklessness. In "Coach Steven", she is only defeated when Pearl outsmarts her by luring her up the hill behind the Crystal Temple. She then used her spear to trip Sugilite, causing her to tumble down the side of the temple and damage herself with her own flail, thus knocking her out and separating the fusion.
- When fused with Pearl, they form Alexandrite.
- When fused with Pearl and Rose Quartz, they form Obsidian.
- Sugilite could also form Obsidian by fusing with Rainbow Quartz.
- When fused with Pearl, and Steven, they form the hybrid fusion Obsidian.
- Sugilite could also form the hybrid Obsidian by fusing with Rainbow Quartz 2.0.
- Flail Proficiency: Her weapon is an enormous flail that uses Amethyst's whip as a chain and Garnet's clasped gauntlets as a bludgeon. Using this flail, Sugilite easily smashes through buildings, reducing a defunct Gem Communications Hub to rubble in a short period. The sheer size of Sugilite's flail combined with the length of its chain gives it much longer range than other Gem melee weapons, much like Amethyst's whip.
- Wind-up Punch: In "Cry for Help", rather than forming her flail, Sugilite twists two of her arms together to deliver a devastating punch.

- Sugilite is the first Crystal Gem to act as an antagonist, the second one being Bismuth.
- Her motivations do not seem to include protecting Earth or humans, instead impressing Steven ("You like that, little man?") and general destructiveness.
- Sugilite is the first fusion of three different Gem types, being made of a Quartz, a Ruby, and a Sapphire.
- According to Ben Levin, Alexandrite is, in theory, taller than Sugilite, due to Alexandrite being composed of four Gems.
- Sugilite could be based on an Oni, which is a Japanese demon, due to the gemstone being first discovered in Japan by Professor Ken-ichi Sugi.
- She also strongly resembles the Hindu goddess of Destruction, Kali. Kali is often portrayed with four arms and a very destructive nature. Sugilite's long and somewhat wild-looking dark hair also resembles common portrayals of Kali. While Kali is often described as violent, she is still usually seen as a destroyer of evil. Some legends even show her with a caring, maternal side, as she is the goddess of Creation too. This also matches with Sugilite's care for Steven.
- Sugilite demonstrates that when multiple Gems are fused for too long, they can slowly lose their individuality.
- Sugilite can be seen as a metaphor for brains over brawn, as she was defeated by Pearl despite being much stronger, due to the mere fact that Pearl's quick thinking and decision-making during their battle was superior to hers.
- The fight between Pearl and Sugilite is very similar to the term "underdog" connecting with the fight between David and Goliath, with David outsmarting Goliath, who was stronger.
- This can also be represented in the song of the episode "Strong in the Real Way", as it heavily implies that Pearl values intelligence over brute force.
- Sugilite seems to have sugilite stones as fingernails faceted in different shapes. The index is shaped like a star while the rest appear to be square.
- Sugilite was the first fusion whose full transformation was seen on-screen.
- She did not want to de-fuse so soon in "Coach Steven", but, in "Cry for Help", she seemed to have de-fused easily. This may be because, in "Cry for Help", she was not fused for a very long amount of time.
- In "Cry for Help", her tower-smashing punch was inspired by the "Twister-Sock Punch" from Popeye and Donkey Kong's "Giant Punch" from Super Smash Bros.
- Sugilite has two songs that refer to her, the first being "Strong in the Real Way". The second is "Tower of Mistakes".
- Sugilite's skin tone appears to be lighter in "Cry for Help". This might be due to Garnet's regeneration in "Jail Break".
- Sugilite appears as a more stable fusion in "Cry for Help" than she does in "Coach Steven", only fusing to destroy the Communication Hub and presumably de-fusing immediately afterward.
- Sugilite is the first and only fusion known to have 5 eyes.
- Sugilite is the first and only known fusion whose gemstones have switched locations between appearances.
- She is the first unstable fusion to have her own voice and have a humanoid shape. The other is Alexandrite.
- Both times Sugilite appears on screen, she is formed to destroy the Communication Hub.
- Sugilite is mentioned in "Know Your Fusion" as part of a strength game Sardonyx had Smoky Quartz play.
- Sugilite's voice actor Nicki Minaj was also indirectly mentioned when Sardonyx said she was being paid even though she had not recorded any new lines for the episode despite being heard.
- Sugilite is associated with the resolution of existential problems, self-awareness, incarnation, and identity; which can be the reason of her reluctance to unfuse or fuse again.
| Amethyst's gemstone on Sugilite, featuring a hexagonal facet. It is a tetradecahedron. It is located on her chest.
|Ruby's gemstone on Sugilite, featuring a square facet. It is a decahedron. In her debut form (from "Coach Steven"), it is located on the palm of her upper left hand. In her latest form (from "Cry for Help"), it is located on the palm of her lower left hand.|
|Sapphire's gemstone on Sugilite, featuring a triangular facet. It is an octahedron. In her debut form (from "Coach Steven"), it is located on the palm of her upper right hand. In her latest form (from "Cry for Help"), it is located on the palm of her lower right hand.|
