Name: Aaron (He doesn't know his parents, so he has no family name)
Appearance: Average height and fitness for his age, Medium-length brown hair, Dull grey eyes, Has an unkept goatee, Wears a brown coat with a hood that he wears most of the time, obscuring his upper face, wears ripped, baggy grey jeans and a t-shirt with the anarchy symbol on it.
Likes: Has no preferences
Dislikes: Has no aversion
Family: Aaron doesn't know his parents, nor does he care who they are. He was found on a shrine and raised in various households before he was old enough to live on his own, then became a hermit.
Favorite Thing: Nothing
Patron: Psyche, a demon in the form of a naked woman with butterfly wings, who saw him and pitied his apathy (He's a nihilist and and is severely antisocial). She has tried since he was a small boy to awaken some sense of love or humanity in him, but has had no success. She has become loyal to him after being with him so long, a loyalty that Aaron abuses mercilessly.
Powers: Psyche can arouse the primal human emotions that lie dormant in Aaron to ridiculous levels, for a short time, allowing him to go into fits of intense emotion that can be dangerous to both himself and others during battle. She also, theoretically, if given access to a source of greater power, could extend this to cause him to regress to previous evolutionary states, becoming a monkey-like being with great strength and agility.
Skills: Very good at math, science and other logical puzzles that benefit from an objective mind (I think you mean "good at" XD)
