@Urbanliner I must say, Power Negation can be a bit OP. Can you give me some examples of things his ability could negate? Like, I get since he cant deactivate his power then he wouldn't be able to receive the benefits of a power like healing.
But, what kind of offensive powers can he negate?
I tried to nerf it by requiring that powers needs to not receive constant attention or it cannot be negated. For example, if one fired a fireball at him, it could be negated unless the fireball user maintained the shape of fireball under their own will. In addition, he is only immune to abilities that specifically target him or any part of his body without any physical manifestation before it would affect him. Sorry for not stating the latter earlier.
