You know the punk on X3 who was known as "the cure?" The nintendo-playing white-clothed wearing kid who could neutralize everybody's mutant powers? Well, his powers worked from only a few feet away or closer. So what the heck would happen if someone used an energy attack at that monkey from a distance? Like storm, cyclops (although he was jean grey lover-fodder by the point), pyro, etc. Could they zap him or would his power eliminate their mutant based attacks before they hit him?
