Peridot

Peridot is a Steven Universe crossover character. She appears in Steven Swap, where Steven Carmichael and Steven Universe switch places for a day. She is voiced by Shelby Rabara.

Appearance
Peridot has lime-green skin, and pale yellow-green hair styled into a tetrahedron shape. Her true eye color is unknown at this time, due to being tinted by her visor, but can be presumed to be some shade of green. Her mouth and tongue are blue. Her gem is located on her forehead, and is shaped like an inverted triangle with flattened corners.

In all of her appearances to date, she wears a sleeveless green V-neck uniform. Her suit is mostly medium green, with a dark-green diamond outline around the cut-out of her neck area, meeting together to form the Yellow Diamond insignia at her solar plexus, with a dark-green portion between her chest and leggings. Her leggings feature yellow diamond-shaped kneepads. She is never seen without her visor, which covers the top half of her face and tints her eyes yellow-green.

Personality
Initially, Peridot was shown to be morose and ruthless. She is skilled with Gem technology and works for the Homeworld Gems as a technician and takes her work seriously, crushing one of her Robonoids underfoot when it was minimally damaged and useless to her in her first appearance during "Warp Tour". In "Marble Madness", she briefly interacts with Steven, questioning him about the current state of Earth before losing interest and attempting to crush him. When the Crystal Gems intervene and reveal themselves, Peridot is shocked and flustered. Peridot also seems to be a bit stubborn. This is shown when she realizes that the Crystal Gems were the ones that have been destroying her equipment, she quickly loses her temper and asks "Why do you keep destroying my things?!". Since "Jail Break", Peridot became increasingly frantic in her attempts to contact Homeworld and stop the Crystal Gems interfering with her mission, as she realized that the Cluster will emerge and that, when it does, it will obliterate all life on Earth. In "Keeping it Together", for example, when flying away with her helicopter fingers, she smiles down and laughs hysterically, and her facial expressions are exaggerated throughout the episode. In "Cry for Help", Peridot interrupts Crying Breakfast Friends! and all other television signals with her own broadcast from the Communication Hub begging Yellow Diamond to rescue her. In "Catch and Release", Peridot kidnaps Steven with the hope he'll be able to fix the Homeworld Warp. When he can't, Peridot becomes hysterical and eventually breaks down with the realization she's stuck on Earth with the Cluster. Before she can elaborate, the Crystal Gems arrive and disarm, poof, and bubble her. After reforming into her natural self with no armor, Peridot is actually rather diminutive and she becomes very juvenile and paranoid, assuming that harmless household items are "weapons" and that every action from the Crystal Gems is driven by hostility. However, once comforted by Steven, she becomes much more relaxed and cooperative, although she still refuses to cooperate with the Gems and sequesters herself in Steven's bathroom. Peridot is very naive when it comes to Earth, especially when the information is not relevant to her mission. She was unaware of the existence of rain or thunderstorms, believed that Steven was a member of a species called "Stevens" because that's what he called himself, and in "Catch and Release", she believed Steven's bathroom to be an archaic think chamber and almost everything in the bathroom to be a weapon. Curiously, she is familiar with the scent of citrus fruit despite her general ignorance of Earth. She is also socially oblivious as she tends to offend all of the Crystal Gems at some point due to her keeping to the Homeworld social hierarchy. Despite her overall unawareness of Earth, she has said that she finds organic life fascinating and is willing to defend the planet from the Cluster and Yellow Diamond. Peridot has been shown to be incredibly stubborn, as it takes several attempts from the Crystal Gems for Peridot to even discuss the Cluster. Often when working, Peridot insists things be done her way and despises compromising. When she does cooperate, it typically takes some persuasion from Steven. She also continues to keep her log, despite the task being a moot point, more or less for a sense of normalcy. She also is vocal and honest about her viewpoints and will bluntly state what is on her mind regardless of the audience. Her statements have put her in harms way on several occasions, whether by the Crystal Gems or her Homeworld superiors. She does take responsibility for what she says and has learned how to keep some of her more offensive opinions to herself. Her recent behavior around the Crystal Gems has shown that she has opened herself up to new ideas and beliefs.

Peridot is incredibly dedicated and somewhat possessive, occasionally to the point of obsession. She becomes visibly upset when she discovers that others have damaged her things and is emotionally attached to her mechanical foot, as it's her only remaining part of her limb enhancers. Peridot is also loyal towards people she respects, as she was driven to complete her mission and return to Homeworld despite no contact from Yellow Diamond and has been shown to cling to Steven when she is scared. However, after realizing that now she is stuck on the Earth without any form of escape, she decides to betray Homeworld and destroy the Cluster with the help of Steven and the Crystal Gems. In "Message Received", after managing to contact Yellow Diamond and pleading for the Earth to be spared, she realized her perspective of her leader has changed and she saw her as the cruel and callous tyrant she is. Peridot then rebels against Yellow Diamond's wishes, cementing her loyalty to the Crystal Gems. Peridot still clings to the Homeworld's social dogma. In "Back to the Barn", Peridot acts very condescendingly towards Pearl due to her position in Homeworld's caste system as a made-to-order servant. She refuses to acknowledge Pearl's skill as a technician for this reason. After a competition between self-built robots, however, Peridot concedes that she may have been wrong. In "Too Far", Peridot shows a strong aversion to fusion, similar to Jasper, referring to Garnet as a "permafusion", and in "Catch and Release" she refers to Garnet as a "filthy war machine" due to the Homeworld belief that fusion should only be used for combat. Peridot has also stated that Garnet makes her "incredibly uncomfortable". Peridot does try to appeal to Amethyst's favor, as she sees Amethyst as the closest thing to a "normal" Gem, by getting her to laugh despite Peridot being incredibly socially oblivious and unfamiliar with the concept of humor. Peridot does feel bad when she unknowingly hurts Amethyst's feelings but is confused until Steven explains it. Peridot has a difficult time apologizing for her behavior but is willing to. It is shown in "It Could've Been Great" that while she likes to follow the rules she gets slightly excited when she breaks them (e.g. sitting in an elite gems seat.) During her time with Steven and the Crystal Gems, she begins to realize that Homeworld's philosophy is very flawed, and she defects as a member of the Crystal Gems. Peridot is extremely self-absorbed, which leads her to continually underestimate the Gems. Even after defecting to aid the Crystal Gems, she thinks mainly of her own needs. Many of her childlike behaviors, particularly her temper and arrogance, stem from her over-inflated ego. This is not to say Peridot is incapable of putting others above herself; she is just not used to having others who are willing to do the same for her. The same behavior extends to her admitting something personal. As she spends more time on Earth, Peridot has started developing a more gracious and compassionate attitude. Peridot prioritizes logic, reason, and objectivity above emotions, while also displaying natural curiosity and a great desire to learn and understand. She is great at problem-solving as she uses her own observations and experiments to make a conclusion, though her experiments are sometimes ill-conceived. Peridot feels that a practical and systematic approach is the correct way to do things while thinking the Crystal Gems are insane for relying on their emotions, particularly when they chose to relax despite imminent danger. Her logical mind tends to put Peridot at odds with the rest of the Gems and has caused her difficulty with communicating. Peridot's reasoning led her to contact Yellow Diamond in an attempt to persuade her to protect the Earth, but ultimately decided to betray Homeworld. When a cause is important to her, Peridot can be just as emotionally charged as the rest of the Crystal Gems.
