I like the idea of a reformed villain,...

Thanks =)
My thinking is it could be possible for her to be the (former) arch-enemy of a one or two members of the League. Or perhaps later in the game I could turn her back into a villain (especially if work causes me to be unable to post on a regular basis).

[quote=MrDidact] but I'm not entirely sure about a super-serum based hero. We seem to have a lot of melee-focused people at the moment.[/quote]
Because of my work schedule it may take a couple of days for me to come up with complete character. But, my current thought is to give her a psychic-based power as well so she doesn't always have to get physical with her enemies. Or some type as ranged attack power.
