Onionthief is very cold and calculating, and a bit of a know-it-all. He is seen giving many answers to other's questions, or questioning other's knowledge. He seems to do this a lot to Nightowl, the rest of the server seeming used to the two having conflicts because of it. He's not one to admit he's wrong easily. He also talks about him being a college student quite often, with his major being computer science. His left ear is nicked in several places and he wears a locket from his baby sister.
