After much deliberation, I have decided to go to TeenWrite as...
A completely brand-new, mint-in-package character!
Her name is Ravena (rah-VEN-uh), and she is a cat burglar from space. (that's cat as in Homo Felus AND stealer dressed in black) Her quirk is that she has the personality of a child, the instincts of a cat, and the brain of a genius, so she's the perfect criminal but only steals the strangest of items.
She also has alot of cat-like physical characteristics, such as fangs and flexibility.
Her foil is Officer Tobias Flyn, a childhood friend who has to try and catch her. But the best he can do is get back the things she steals by bribing her with his police badge.
