Jasper

"Fusion! always Fusion... is that the only trick you Crystal Gems know?" Jasper is a bully in the truest sense. Deep down, she's afraid there's something wrong with her, so she has to feed her ego. She has to put other Gems down to stay on top. Who she is and where she's from gnaws at her all the time. She has a fantastic reputation, she's considered the greatest Quartz soldier produced on Earth, and that might impress other Gems, but it will never be good enough for her. She will always feel held back, and she'll always feel the need to go further to get ahead. The Gems live in a society with a very rigid social order and caste system, and Jasper has completely bought into that, and her self-worth is attached to it. Because she loves honor, fighting, making her mark, and winning the battle, she'll actually go against her programming a little bit just to be the winner. So she can be self-destructive at times. She is tragically obsessed with proving her superiority.
