Peridot

Peridot is a character from the Steven Universe fandom.

Character
Peridot is a "Gem", an alien being that exists as a magical gemstone projecting a holographic body.

Peridot used to be aligned with Homeworld, a Gem empire that strives to create more Gems by hollowing out planets and depriving them of their resources. She didn't question this goal and followed it single-mindedly, often presenting herself as serious, aloof but also very intelligent.

After ending up trapped on Earth due to interference of the Crystal Gems, Peridot is at first desperate to return to Homeworld and hostile against anyone who will stand in her way. But encouragement from Steven Universe allowed her to see the beauty in Earth and she ended up getting along very well with Pearl, Amethyst and Garnet, the other Crystal Gems. This all led to Peridot directly rebelling against her former superior, Yellow Diamond, after a failed attempt at trying to reason with her on the matter of sparing the Earth, making a fully-fledged Crystal Gem.

Trivia

 * According to storyboard artist Maya Petersen, Peridot is supposed to be the show's ace-aro representation. However, Petersen has also acknowledged that the word of a storyboard artist is not as official as the word of the creator of the work itself, directly citing the term "Word of Saint Paul" (coined by TvTropes: "When the Word of Saint Paul contains (or is perceived to contain) mistakes or misunderstandings of the original creator, they can easily carry the germ for future debates").
