"Peridot" is a Gem who made her debut in "Warp Tour." She is a reformed antagonist of the series.
AppearanceEditPeridot has light green skin and neon green eyes. Her fingers are not directly attached to her body, but instead float around where her palm would be. Peridot's hair is yellowish green, and styled into a tetrahedron shape. A light green visor covers half of her face. She wears a V-neck body suit that covers all of her body, except for her upper arms and neck. Her body suit is mainly composed of dark green and has a black diamond outline around the cut out of their neck area; meeting together to a light green diamond in front, with the lower half of her suit being black and dark green around her upper legs. Peridot's sleeves and boots are mostly composed of green and black as well. She has light green, diamond-shaped knees and elbow pads. Her gem is located on her forehead and is shaped like an inverted triangle with rounded edges.
Thus far, Peridot has been shown to be cold and ruthless. She appears to be some sort of scout or technician, and takes her work seriously, crushing one of her Robonoids when it was damaged in her first appearance in "Warp Tour." In "Marble Madness," she shows herself to be slightly arrogant and does not have a high opinion of humans, and attempts to crush Steven with a giant hand after briefly interrogating him. She is also somewhat like Pearl, in that they're both very intelligent and become easily flustered when their plans fail.
Despite her cold nature, Peridot is easily flustered. She also seems to be rather childish when things do not go her way. When Peridot realized that the Crystal Gems were the ones that have been destroying her equipment, she quickly lost her temper and asked "Why do you keep destroying my things!?". She also complains to herself when Jasper disregards their mission directives and instead chooses to return to the Homeworld.
Peridot also seems to be very naive when it comes to Earth, especially when the information is not important to the mission, such as assuming that Steven's Crying Breakfast Friends! sticker was a sign to show that the Galaxy Warp had been compromised. She also believed that, while interrogating Steven, there were a species called "Stevens", just because he addressed himself by his name.
