You know how telekinesis works, right? It's... [i]kind[/i] of the same thing. For one, it's much stronger, two, it works one the user also, granting the ability to, say, fly or throw a stronger punch. For three, it works on other humans/creatures. For example, he could make an enemy hit themself by controlling their fist. Know what I mean? It also works on magic, so if someone using ice magic shot icicles at him, he could use his magic to shoot them somewhere else.
