PP has powers, outside of the ring. When he's wrestling, he lets himself be pretty much a 'normal' dude. He finds it fun to just be normal against all of the other 'normal' people. After all, if you can do anything in the ring, shit can be boring. Outside of the ring, however, he is a being from Broken Oswald's mind, a being that is outside of all space and time. His personality is a mix of two from GT's past, Death Incarnate and Psychopath(kinda like Mick Foley as early Mankind). Which is why he can hop any timeline, and any dimension of any universe he wants.

However, for now, there's no true 'depth' of him to explore. He is what he is. A psycho murdering clown lookin' mfer that acts how he wishes to act.
