Citrine

"Now We're Going To Finish The Game FOR GOOD!"
Citrine is a high-ranking soldier from the Gem Homeworld, who sometimes scares weaker Gems such as Peridot. As mentioned, she normally comes off as a ball of sunshine who loves to have fun and is always eager to try anything new. However, she's also an inconsiderate sociopath who always tries to do whatever she wants, whenever she wants. To her, fun usually consists of mindless destruction, laying waste to inferior civilizations, & the pain and suffering of others. She also has a short attention span, so can be easily distracted from her missions.
However, while she does come off as a ditz, Citrine does have plenty of common sense and can easily manipulate others when she wants. The only times she gets upset are when she's losing a fight or when things don't go her way. When that happens, she becomes a horrifying monster who goes on violent rampages, determined to take out her enemies as quickly as possible. Citrine may act like she wants to be everyone's friend, but she doesn't know what true friendship or teamwork is. She only works with others when she finds them amusing or when she needs their help to get what she wants. Once they serve their purpose, she's not afraid to abandon them in a heartbeat. There are only Gems she'll obediently listen to are ones that scare her such as Jasper & Yellow Diamond. even also that She was defeated by the Centurions of Demacia along with Topaz
