And also there's the problem of how would it work for, say, bestial metahumans. If my character Rori went in it would they lose, say, their wings and not get them back when they came out of the zone? That kind of thing is ddifficult to figure out for those whose power is an actual physical change of their body. I mean I have an NPC (who I need to repost) with power negation but he has to touch them for like an hour to negate a power for a week, if not less xP (also he's an NPC)
