So X-ponent doesn't seem to have an actual ability, even though he claims to. And despite the way he behaves and his brother's concern for him, he's not an idiot. I doubt he truly misunderstands what 1^x power is. Will we ever learn if he has an actual power, and if so what it is?
darius404--Not to worry. X-Pletive and X-Ponent are significant characters, and their story will play a big part in the final story arc (which begins with Issue #12).
