Sugilite is colossal, almost nearly equal in size to Alexandrite. She features four, 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-violet hair kept in an untamed style similar to Amethyst's. Her skin color is lavender, like Amethyst's. She appears to have purple fingernails painted to appear as gems themselves.
Her Gemstones are located on her chest, and on the palms of the hands of her lower arms.
She wears a ripped, dark-purple, black and burgundy costume similar to Garnet's body-suit, and a visor covering her lower eyes. She has four arms, which are connected at her sleeves. Her leggings have rips/cuts that are similar to Amethyst's.
Her top is now split into two colors; violet and dark-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, and also becomes an even darker shade of violet, and her skin takes on a more lavender hue, although this could be due to the lighting. Ruby and Sapphire's gems 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|
Sugilite cares for herself, first and foremost. Though she carries out mission objectives, she is very impulsive and does not hesitate to use force to achieve personal desires. She combines Garnet's headstrong, unwavering nature with Amethyst's indulgence, as well as her negative attitude towards authority. The resulting personality is a volatile mix that is highly aggressive, and dangerous to everyone she encounters. This causes at least one perilous situation, wherein Sugilite, enraged that she was left behind during a mission and asked to unfuse, viciously attacks and severely injures Pearl. She seems to possess some of Ruby and Sapphire's feelings towards separating.
Despite her destructive nature, she seems to retain an attachment to Steven. She avoids targeting him directly during her rampages, though ironically she inadvertently causes a chunk of debris to fly off at Pearl, who deflects it and hits Steven in the face; and wants 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.
An absolute juggernaut in combat, Sugilite uses her sheer strength to smash objects and size to overpower and crush any opponents.
Though not as acrobatic and nimble as Opal, Sugilite makes up for it by sheer size; her long legs allows her to cover a lot of ground quickly and leap long distances. Sugilite has no known weaknesses, except her own 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 get hit on the head by her own flail, thus knocking her out and separating the fusion.
- 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 weapon, Sugilite easily smashes through buildings, reducing a defunct Gem Communications Hub to rubble. Due to the sheer size of the weapon and the length of the chain, this gives much longer range than traditional 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.
- Main article: Sugilite/Quotes
- Sugilite is the first Crystal Gem to act as an antagonist.
- Her motivations do not seem to include protecting Earth or humans, instead impressing Steven ("You like that, little man?") and general destructiveness.
- 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 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's still usually seen as a destroyer of evil. Some legends even show her with a caring, maternal side.
- Sugilite demonstrates that if multiple Gems are fused for too long or if the fusees or incompatible, they can slowly lose their individuality.
- Sugilite is the first Gem Fusion to act as an antagonist, the second being Malachite.
- Sugilite can be seen as a metaphor for brains over brawn, as she was defeated by Pearl, despite being much stronger, due the mere fact that Pearl had outsmarted her.
- The fight between Pearl and Sugilite is very similar to the fight between David and Goliath, with David outsmarting Goliath.
- 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 as a star while the rest appear to be square.
- Sugilite was the first fusion whose full transformation was seen on-screen.
- Sugilite was one of five fusions to be fused more than once. The other four being Garnet, Sardonyx, Alexandrite, and Opal. Stevonnie is not included due to not being a pure gem fusion.
- She didn't 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", Amethyst and Garnet were reluctant to fuse in the first place, making it easier for her to de-fuse.
- 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 reference her, the first being "Strong in the Real Way" and the second is "Tower of Mistakes".
- Sugilite is also a three way fusion of Ruby and Sapphire (that make up Garnet), and Amethyst.
- The form Sugilite had after Garnet regenerated and before Amethyst regenerated was never seen.
- In "Cry for Help", Sugilite is much larger compared to how she appeared in "Coach Steven".
- Additionally, 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 afterwards.
- Sugilite is the first and only fusion to have 5 eyes.
- Sugilite is a rare purple cyclosilicate mineral that was named after the Japanese petrologist, Ken-ichi Sugi.
- Sugilite's chemical formula is KNa2(Fe, Mn, Al)2Li3Si12O30, where manganese, as an impuritity, gives it its purple color.
- Iron and aluminium make it range in color from pinkish-purple to deep bluish-purple.
- Sugilite is not a traditional birthstone.
- Sugilite is associated with the resolution of existential problems, self-awareness, incarnation and identity; which can be the reason of her reluctance to unfuse.
