Prima

Prima comes across as a bubbly, excitable person. Someone who's hyperactive, optimistic, peppy, and amicable. Almost like the host of a show for young children, always smiling, never sad.

The truth is that Prima is a total monster—heartless, selfish, cruel, ruthless, vicious. She thinks hurting people is hilarious, thrilling, and satisfying. Empathy is completely foreign to her; she isn't kind, she doesn't want to help others, and she only understands feelings from an analytical standpoint, like a test she's studied for.

Being a complete genius with a photographic memory, an athlete with incredible strength and swiftness, and a stealth expert with loads of blackmail, she is essentially invincible. She has the world within her grasp and she thinks she can do anything she wants. Life is like a game, and she's winning.

Prima is the younger sister of two daughters. Neither ever knew their father, and aren't sure if they're fully related or not. Their mother, Yana, was an alcoholic and deeply demented, doing strange things that put her daughters in danger. The two may as well have been orphans, because they were forced to behave like street orphans in order to survive when their mother was deeply unfit to do it herself. Growing up in a ghetto, there was no one around to whisk them away. They both learned con artistry, manipulation, and stealth as they stole supplies or tricked people out of theirs.

Having dedicated all their time to improving themselves in their mutual thirst for power, they were able to complete a plan to emigrate overseas; with forged documents, stolen currency, and expert levels of trickery. It was a rocky process even for a pair of geniuses like them, but they got through by the skin of their teeth. Prima's sister arranged a home for them to share and they were enrolled in school nearby. Documents were forged that declared them emancipated, allowing them to live without a legal guardian.

Prima flourished in school as a complete social butterfly, but it quickly became apparent that there's something wrong with her, in the sort of way that no one was willing to tolerate, no matter how much of a social juggernaut she was. It's one thing to be the traditional mean girl; it's another when the problem is her physically harming people for a laugh, being interested in grotesque things, humiliating, degrading, and ruining people because she finds it funny, and generally behaving in a bizarre manner. However, she wouldn't take "no" for an answer and forced people to remain her friends through blackmail and intimidation. Any and all investigations into her actions by figures of any authority were complete failures; she's a genius, and covers all her tracks. Not to mention she can lie like the best of them.
