Appearance
Abaddon is a woman in her twenties with red hair and gold eyes. She wears a short red one strapped battle dress that resembled leather straps on top of a black leotard that had a top that was styled like flames which covered a healthy portion of her rather large breasts but left much to the imagination. On her right arm, is a long black and red sleeve. On her left is a black resistance sleeve. She wears long socks that covered her legs with a leather strap around them. On her feet are a pair of black and red heeled boots.
