Well his power is quite literally "I think therefore I am". He thinks that he is on the other side of the world and he is there. He thinks he is in the depths of space and poof there he is. And I am not sure, but that at any moment part sounds like he can step through time too though I may be wrong. Another thing is that he is another character that can't die, he would literally want to die for anything to pose a threat of killing  him. I mean he can't even get hurt unless he thinks "sure I am hurt". I am not trying to be mean, but a character that can basically say "I can do everything because I think I can" worries me some.
