I was thinking about a lesbian female tiefling sorceress who practices a slight variant of magic- she casts water and frost-based equivalents to common fire spells. So instead of fireball you have waterball, and instead of burning hands (if that one even exists), you have a spray of ice shards. She isn't really evil, so much as disgusted with the discrimination she usually gets from paladins who see her as some kind of living evil and thus in need of a good smiting. She could go either way on the bondage end of things, being either a bondage witch or the mistress of one (or the person you threaten your bondage with with).
Might not work too well, depending on the kind of cyberpunk.
