Kara, often called "The Ultimate Despair", she gets a kick out of being sociopathic and she likes to cause despair in others, just because she finds it beautiful. However, she never lies, she will always tell her version of whatever she sees, even if it might cause others to fall into despair.

She is also the one who posted the "Despair Video" a film exposing the darkest truths of the world
