Peridot

 (specifically Peridot Facet-2F5L Cut-5XG) is a member of the Crystal Gems who made her debut in "Warp Tour". She was originally a Homeworld Gem technician and a certified Kindergartener. After being stranded on Earth following the events of "Jail Break", she acted as a recurring antagonist until becoming more of an anti-hero and pseudo-antagonist by establishing a truce with the Crystal Gems in "When It Rains" to help them save the Earth from the Cluster. She officially became a member in "Message Received" after she defied her Homeworld superior, Yellow Diamond. For some time, Peridot lived in the barn with Lapis Lazuli. As of "Raising the Barn" she resided in the Crystal Temple. In the events of Steven Universe: The Movie and onward she lives with Lapis Lazuli and Bismuth in Little Homeworld.

In The Neptunians (series), she is a member of the Neptunians along with Pearl, another crystal gem.

Appearance
Peridot has lime-green skin and pale chartreuse yellow hair styled into a tetrahedron shape. When she blushes, it is green. Her true eye color is dark green, which is usually tinted by the yellow color of her visor. Her visor works similar to Garnet's, it being a part of her form yet not molded to her body. Her mouth and tongue are bluish-gray, and she has a pointed upper lip. Her gemstone is located on her forehead.

Pre-regeneration (debut)
In all of her appearances up to "Made of Honor", Peridot 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 to form the Yellow Diamond insignia at her solar plexus, with a dark-green portion between her chest and leggings. Her leggings cover her feet and feature yellow toes and diamond-shaped knee pads. She is never seen without her visor, which covers the top half of her face and tints her eyes yellow-green. She has a slightly curvy figure, with wide hips, a small waist, and a round chest. From her first appearance in "Warp Tour", Peridot wore limb enhancers, which have been disposed of as of "Catch and Release" when Amethyst dropped them into the ocean. These artificial extensions are bright green and flare out toward the wrists and ankles, which are colored very dark green. The arm enhancers also feature artificial metallic fingers which are not directly attached but instead levitate around where the palms would be. The leg enhancers used to serve to enhance her height; without them, she is only about as tall as Ruby and Sapphire and slightly taller than Steven.

Post-regeneration (current)
After her regeneration shortly before "Change Your Mind", Peridot's bodysuit now covers her entire chest and is green at the top with a pale chartreuse yellow star on the front, and her leggings are bright green with a dark green star on each knee. The area between her chest and leggings remain dark green. She also now wears pale chartreuse yellow boots. Her visor is bigger and is now transparent yellow, butterfly-shaped, and exposes her forehead. It also tints her eyes as a brown-gold color as opposed to green with her previous visor.

As shown in "In Dreams", Peridot's visor is removable.

Other Outfits
In "Reunited", Peridot wore a yellow dress and pink shoes during Sapphire and Ruby's wedding. The dress and shoes were physical as opposed to holographically generated and she wore them over her standard outfit.

Personality
Initially, Peridot appeared to be calculating, ruthless, and loyal, as shown in her readiness to kill Steven and the other Crystal Gems in "The Return" when asked to by a higher authority. She takes her work seriously, crushing one of her Robonoids underfoot when it was damaged and useless to her during "Warp Tour". Examples of Peridot's loyalty are shown during the events of "Jail Break". Although she disagrees with how Jasper is running their mission and is shown to be annoyed, she still takes orders and goes along with what Jasper has in mind. Another example of her loyalty is shown when 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. After "Jail Break", Peridot became increasingly frantic in her attempts to contact Homeworld, knowing that the Crystal Gems' continuous interference with her mission would leave her stuck on Earth when the Cluster emerges and destroys the planet. Her behavior is shown to be more erratic, 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", she interrupts all television signals with her own broadcast from the Communication Hub begging Yellow Diamond to rescue her. She even resorts to kidnapping Steven so he can try to repair the Homeworld Warp with his healing spit during "Catch and Release". When Steven is unable to solve her problem, Peridot becomes hysterical and breaks down with the realization that she is stuck on Earth with the Cluster. After reforming into her natural self with no limb enhancers, she becomes very juvenile and paranoid, assuming that harmless household items are "weapons" and that hostility drives every action from the Crystal Gems. 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.

Because Homeworld is a caste society, Peridot viewed the Crystal Gems as some being more superior than others, which often led to her unintentionally offending them for a long time. In "Back to the Barn", she acted very condescendingly towards Pearl due to her position in Homeworld's caste system as a made-to-order servant and refused to acknowledge Pearl's skill as a technician for this reason. After a competition between self-built robots, however, she concedes that she may have been wrong. In "Too Far", She shows a strong aversion to fusion, referring to Garnet as a "permafusion". 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. She has also stated that Garnet makes her "incredibly uncomfortable." She 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 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 Gem's 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. She admits to having some lingering feelings over Homeworld in "Gem Drill". She reveals that while she had made peace with her decision to defect, it was tough to give up the old emotions of her past life.​​​

Peridot repeatedly shows arrogance and self-aggrandizing behavior. It is likely that her inflated ego, slight condescending attitude, and bragging (ex: calling herself the new leader of the Crystal Gems) is a way of compensating for her own insecurities. As shown in "Too Short to Ride", she suffers confidence issues due to seemingly having no Gem powers of her own since Homeworld has lacked in resources to give powers to her kind upon creation. However, this quickly changes when it is discovered that she has latent ferrokinetic powers with which she made the most out of her time at Funland with Steven and Amethyst. In "Earthlings" Peridot overestimated her ferrokinesis and bragged to Jasper about it. In "Back to the Kindergarten" she was finally convinced to leave the bathroom when Amethyst mentioned she could make her and Steven feel dumb with how much Peridot knew. In "Made of Honor", Peridot treats Bismuth's arrival as less important than her being the only one to keep her drink up. Out of all of this egocentric and arrogant behavior, the most extreme example was by far during "Reunited". When Blue Diamond attacked, despite Peridot's lack of real damage, she demanded Blue Diamond to fight her and then congratulated herself for her trajectory when Bismuth threw her. However, this behavior is not without consequence. When Yellow joined Blue in the attack, Peridot without hesitation went to taunt her, not fearing the by far more dangerous Gem. This leads to Yellow immediately poofing her.​​​​​

Peridot formerly prioritized logic, reason, and objectivity above emotions. While she was not apathetic, she tended to fall back on her intellect which is much more developed than her interpersonal skills. She is great at problem-solving as she uses her observations and experiments to make a conclusion, though these are often eccentric. Peridot used to feel that a practical and systematic approach is the correct way to do things and has had trouble reconciling this with the Crystal Gems, who make decisions based on their feelings, particularly when they chose to relax despite the imminent danger in "It Could've Been Great". Her reason-based decision-making led her to take a different approach to the other Gems in saving the Earth. She contacted Yellow Diamond, whom the other Gems considered evil because she believed the Gems would inevitably mess up in their plan, and tried to persuade her to save the Earth by suggesting alternative non-lethal means of using Earth's resources. When a cause is important to her, Peridot is just as passionate as the rest of the Crystal Gems. Ultimately her determination to spare Earth's life led to her betrayal of Homeworld. Hailing from Homeworld, Peridot was very naive when it came to Earth and often offended the Crystal Gems while spending time with them. As seen in "Marble Madness", she approaches interaction with organic life with Homeworld's ideology, since when she interacts with Steven, she tries to crush him with a mechanical fist after he outlives his usefulness, believing organic life to be a lower life form. She does not quite comprehend Earth's figurative speech patterns, which often leads her to misinterpret expressions, metaphors, sarcasm, and humor. She was unaware of the existence of rain or thunderstorms and believed that Steven was a member of a species called "Stevens" because that is what he called himself. Curiously, she is familiar with the scent of citrus fruit despite her general ignorance of Earth. Despite her overall unawareness of Earth, Peridot has said that she finds its organic life fascinating and is willing to defend the planet from the Cluster. Since then, she has accepted Earth as her new home. In "Earthlings", she expresses her love for the Earth by trying to explain how living on Earth can "free you", indicating that she loves how the Earth has allowed her to discover her own personality, not what Homeworld tells her she is. In "Room for Ruby", she agreed initially to teach Navy about the traditions of Earth when she was living in the barn.

Peridot has been shown to be incredibly stubborn. As shown when the Crystal Gems destroy her equipment, she gets frustrated when she does not get her way and quickly loses her temper. It takes several attempts by the Crystal Gems for Peridot to even discuss the Cluster. Often when working, Peridot insisted things be done her way and despised compromising. She continued 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 used to bluntly state what was on her mind regardless of the audience. However, Peridot does take responsibility for what she says and has learned how to keep some of her more offensive opinions to herself. As time went on, her behavior around the Crystal Gems has shown that she has opened herself up to new ideas and beliefs. She is rather bad at lying and will tell the truth when pressed, as seen when she tried to lie about the Diamond Communicator and why she hated shapeshifting but told the truth when asked again.

Peridot is incredibly dedicated and somewhat possessive, occasionally to the point of obsession. She used to be emotionally attached to her mechanical foot, as it was the only remaining part of her limb enhancers. 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, despite being obsessed with her formerly. Peridot has shown an obsession with objects and entertainment, all of Camp Pining Hearts and has a love for things with alien symbols such as boxer-shorts, and stuffed animals. Her wants can be seen as quite childish at times, as Mr. Smiley actually thought she was a kid.

Peridot used to be extremely self-absorbed, which lead her to underestimate the Crystal Gems continually. Even after defecting to aid the Crystal Gems, she still mainly thought of her needs. Many of her childlike behaviors, particularly her temper and arrogance, stemmed 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. As she spends more time on Earth, Peridot has started developing a more gracious and compassionate attitude. This was mainly seen through trying to be friends with Lapis Lazuli and the Crystal Gems. The same behavior extends to her admitting something personal. "Beta" shows a much more considerate and thoughtful side to her. She shows Steven and Amethyst around the renovated barn, entertains them with her "meep morps" and powers and tries to convince Amethyst that she is better than Jasper by showing her the Beta Kindergarten. She also shows her dedication to her friends by telling Jasper she is a Crystal Gem and trying to use her metal powers to help fight. When Lapis was sad about how she took the time to learn about Earth when Navy was able to understand for the first time, Peridot comforts her.

Steven Universe: The Movie shows that Peridot is far less self-absorbed and much more open and cooperative as she works with Bismuth and Lapis to build Little Homeschool, and analyses Spinel's injector though she is still eccentric and goofy when she helps try to get the gems' memories back. Steven Universe Future shows that she has turned to gardening and teaching about farming and growing plants in Little Homeschool.

Powers
Peridot possesses most standard Gem abilities. However, it is revealed in "Too Short to Ride" that Peridot was created on Homeworld during Era 2 when the planet's resources had diminished greatly due to millennia of gem manufacturing. Due to the lack of resources, Peridots made on Homeworld appear to lack certain powers, which is why they are equipped with technological enhancements. For instance, Peridot claims in "Too Short to Ride" that she cannot shapeshift at all.

Skills

 * Intelligence: In "Kindergarten Kid", Peridot describes herself as smarter than the average Peridot. Additionally, she was able to instantly memorize the musical scale of a ukulele after hearing Steven in "It Could've Been Great", demonstrating perfect (or at least exceptional relative) pitch.
 * Architecture: Being a "certified Kindergartner", Peridot has extensive knowledge regarding the location, mineral, and injectors used to create Gems and the state of such Gem by how they appear as themselves and the hole they had come out of. She was sent to Earth in order to check the Cluster's progress in it gained physical form. In "Message Received", she has ideas about how to take advantage of Earth's unique resources without destroying the organic life. In "Beta" as Peridot educates Steven and Amethyst of the intricacies of the Prime and Beta Kindergartens and why their overall quality is far apart from each other. As a result, Peridot knows what would be needed to create the perfect Gem.
 * Engineering: Peridot is able to easily improvise new creations out of existing technology, such as her battle robot in "Back to the Barn", her improvised cannon in "Kindergarten Kid", a gem drill to reach the core of the Earth with Pearl's help, and some of her artistic "meep morps" shown in "Beta". Peridot has some construction skills, as she managed to rebuild the communication hub to a usable state and was seen trying to fix a warp pad. In "Change Your Mind", it was shown that she, along with Bismuth and probably Lapis, was able to repair Blue and Yellow Diamond's ship to a fully functional state. Despite rivaling Pearl in engineering skill, Peridot has a far superior knowledge and utilization about Gem-tech than Pearl due to the latter's lack of knowledge on current Gem technology for thousands of years. She also is knowledgeable of old Gem tech, as she was able to find the Cluster's coordinate files on the Moon Base.
 * Horticulture/Agriculture: Peridot learned about Earth's plant life and decided to use her skills from Kindergarten management to cultivate vegetables at the farm. In Steven Universe Future, Peridot is shown running a greenhouse in Little Homeschool and teaching other gems about gardening.
 * Piloting: Along with Pearl, Doc, and Navy, Peridot is able to fly Homeworld ships. She is seen briefly interfacing with her ship's controls, setting a course to the Gem Homeworld.

Natural Abilities

 * Immense Durability: By her own admission in "Kindergarten Kid", Peridots are rather durable and can evidently take much harm unscathed. In "Keeping It Together" she can easily shrug off having a heavy piece of Kindergarten machinery crashing down on her without "poofing". In "Kindergarten Kid" she endures multiple crashes and falls in one day, with her physical form remaining intact.
 * Gem Storage: Peridot has the ability to materialize different items out of her gemstone. In "Warp Tour", she summoned an EMP device. She shares this ability with Garnet, Pearl, and Spinel.
 * Bubbling: As revealed in "Kindergarten Kid", Peridot is able to bubble objects. Her bubbles are lime green and are sent to The Barn instead of being sent to the Burning Room inside the Temple because the Barn is where Peridot considers home.
 * Photokinesis: In "It Could've Been Great" Peridot is shown using her gemstone to project a green light, like a flashlight. She shares this ability with Garnet, Pearl, Eyeball, Doc, and the Rutile Twins.
 * Enhanced Strength: Even with her limb enhancers, Peridot possesses very little physical strength and has difficulty just lifting Steven and pieces of a Warp Padnormally. In "When It Rains", she failed to remove a panel from a Prime Kindergarten Control Room wall, which Steven removed with relative ease but this may have been because of his gem strength, or possibly just for comedic effect. However, in "Reunited" Peridot is able to knock over Mr. Frymanwith a couple of flowers alone, suggesting some degree of considerable strength when compared to a human.

Unique Abilities

 * ​​Ferrokinesis: Peridot believed that she had no unique powers until in "Too Short to Ride", it is shown that Peridot can levitate and control metallic objects. The extent of her powers (whether she manipulates magnetism or just the metal) is still unknown, though given as she was able to use the ability on her tablet without damaging the device's circuitry, magnetism appears unlikely. It is possible this ability is what made her so proficient with her limb enhancement's fingers, particularly the 'finger copter' ability.
 * Lifting: It can require some physical and mental strain on Peridot's part depending on the weight of the object(s), but once lifted off of the ground, her ferrokinesis makes it effectively weightless. In "Beta" she can hold up an entire one-man band of metal instruments (though drops them after concentrating on playing the harmonica). In "Room for Ruby", Peridot is seen casually using this power to raise an umbrella over her and Lapis' head, and raise a trash can lid up to Lapis while she, Steven, and Pumpkin are standing on it, showing she has mostly mastered this ability. In "Earthlings", once properly motivated, she proves capable of using this to throw a piece of scrap metal with enough force to impale the now corrupted Jasper through the chest, poofing her. In "The New Crystal Gems", she is shown to have more control over this ability, being able to lift up trucks and other cars. In the same episode, when Peridot and Lapis were fighting over a car, she was not overcome by Lapis' hydrokinesis. The exact maximum she can lift with this ability is unknown, but she is capable of lifting several tons with little effort.

Currently

 * Earth Tablet: A gift from Steven (who received it from Greg), Peridot uses it to explore the media and express her feelings shown by "Too Short to Ride", she also said it is something to love, for she no longer has advanced gem technology. Peridot shown to be able to use Earth technology as she was able to use a tablet with little guidance from Steven, possibly because the interface is similar to her limb enhancer's holographs.
 * Attack Drones: Built sometime before "Gem Harvest", Peridot created attack drones to defend the barn in case of invasion. Each is a spherical turret, moving a propeller and controlled by remote. Their design is similar to Peridot's Flask Robonoid; whether these are new drones made from their design or simply modified robonoids is unknown.
 * Trash Can Lid: Since the unspecified point of time, during "Change Your Mind", Peridot, combining her ferrokinesis ability, can stand on a trash can lid to fly around as transportation, as well as giving others a lift using the handle on the bottom.
 * Robonoids: When she served Homeworld, Peridot could control different types of spherical robots known as Robonoids. There are four types of known Robonoids: Flask, Plug, Hand, and Visitor. They can perform multiple functions, such as fixing a Warp Pad and activating Kindergartens. As of Steven Universe: The Movie, she seemingly has them back, sporting a new design with her visor on them, they are also seemingly used for more analytical purposes, and scanning with the holes of the Diamond shape.

Formerly

 * Limb Enhancers: Mechanical body extensions Peridot had worn since her debut until the Crystal Gems capture her in "Catch and Release". She is very skilled with advanced Gem technology and is surprisingly dexterous, able to avoid most attacks during her confrontation with the Gems in "Friend Ship" by using her finger attachments as an alternative to walking. However, Peridot has little to no skills in hand-to-hand combat and is thus totally reliant on her limb enhancers for offensive capabilities. In "Catch and Release", her only tactic was that she kept slapping Steven only after realizing it hurt him. She originally tended to assume that unfamiliar objects (such as those in Steven's bathroom) are weapons, as seen in "Catch and Release".
 * Anatomical Separation: Peridot could separate sections of her limb enhancers by touching a lime-colored button at the zone she wants to remove.
 * Holographic Interface: Peridot could project a holographic touchscreen from the fingers of her right hand, in which she could control and connect to different forms of Gem technology, as well as use to search for specific data, and record logs.
 * Tractor Beam: Peridot could produce a light-green tractor beam from her left hand to move objects/people.
 * Blaster: Peridot could transform the fingers on her right arm into a blaster that could charge and fire an electrified energy ball that would explode on impact. Charging it for a second produces a shot powerful enough to blast through the ceiling of the Ancient Gem Colony Ship. Charging it for several seconds produces a large shot that can knock down a thick stone pillar, and has enough recoil to knock Peridot onto her back. Peridot appeared to have been unaware of this feature, expressing clear surprise upon her first using it.
 * Rapid Fire: Peridot is able to fire a large number of energy balls in rapid succession.
 * Helicopter Fingers: Peridot could expand the fingers of either hand and spin them rapidly enough to fly.
 * Wall-Scaling: Peridot could freely run up vertical walls without falling.
 * Gem Destabilizer: In "Jail Break", Peridot wields a Gem Destabilizer, an extremely potent but non-lethal tool used to subdue enemy Gems. As seen used on Garnet, the Gem will start to crack apart at the seams, and poof into their gemstones.
 * EMP device: In "Warp Tour", Peridot placed a device on the Galaxy Warp Pad before she left Earth. About three seconds after being placed, the device exploded, disabling all of her Robonoids. Peridot pulled this device out of her gemstone, but considering that she has not used or mentioned it since, it is likely to have been merely stored in her gemstone rather than a summoned weapon. The device seems to be highly advanced, as Pearl's pulse bomb in "Political Power" (which appears to be made from human technology) was unable to disable even a single Robonoid, though it did succeed in knocking out the power in Beach City.
 * Peribot: A robot that Peridot created focuses on brute strength. It has enough destructive strength to crush boulders of equal and greater size, and its short stature is used as leverage to support its arms. Despite its appearance, the robot's top running speed is enough to keep pace with Pearlbot. In case of an emergency, the tubing of the arms can serve as an escape tunnel. It suffered severe damage in "Message Received".

Trivia

 * Peridot is asexual and aromantic according to Maya Petersen, a storyboard artist.
 * Peridot is thousands of years old according to Lapis.
 * The two times Peridot has been poofed have been for opposite reasons. The first time was by Garnet because she was a Gem loyal to Yellow Diamond threatening both the Crystal Gems and the Earth. The second time was by Yellow Diamond because she was a Crystal Gem protecting Earth.
 * She has an overly technical term for most body parts (e.g. ears are "head holes", hands are "touch stumps", feet are "gravity connectors", etc.). Whether or not this is a common trait among modern Homeworld Gems or a personal quirk is currently unknown.
 * She has a Twitter page operated by Jesse Zuke, although it is currently inactive because they left the show.
