Mine interest hath been stolen. Give it back, you jerks.
Anyway, I was thinking about prospective powers. Are there any out there that are downright banned? For mine own, I was thinking of giving them the ability to transmute and manipulate non-living matter. Turning coal into gold, for example. To off-set that strength, they would require physical contact with whatever they're changing. Also, they can't create new matter from nothing, or if they could it would drain the person heavily.
Would that work out?
Okay, Edward Elric.
