Abbadon.

Abaddon is untrustworthy, greedy, and quick to anger, but also very cunning. She adapts quickly, as she managed to use modern technology, weaponry, and armory to her advantage despite being here only a short time in the present. She is a brilliant strategist, able to secure several meatsuits and weapons for her subordinates in one move, as well as to locate and take prisoner two hunters who could be used as bait for the Winchesters, effectively luring them in and briefly overpowering them.

Although Abaddon enjoys causing suffering to others and basks in the fear her victims have of her, she prefers to kill her victims in quick, brutal ways and move on. She views killing as "art"; when comparing her murder of Father Thompson to her killing the Men of Letters, she judged how she slaughtered the Men of Letters to have been better, commenting that her killing of Father Thompson merely "got the job done."

Abbadon’s human vessel is a ginger woman who’s bust is quite prominent in her leather jacket and black outfit.
