If you was in the justice league what would be your power and what villian would you want to challenge
I would have the power of shadow manipulation. I can travel through shadows, and control any shadows from any distance (like manifest them into physical forms). I'll go against... hmmm have to think about this, the Joker. Since I don't have a no-kill rule this ought to be a pretty fast fight.
Sorta like water bending in avatar but to a point where I can turn into water and air moisture and any part of my body can form in random places who I'd fight? anyone and all (finishing technique turn into air or water enter in enemies body freeze inards and slowly rip him in half)
