Ever heard of the Superpower Lottery? Well, kid, you just won the grand prize. You can create, change, or destroy things or even alter reality just by thinking about it. The key issue here is how far they can take this. A character with a mild form of this power (which isn't seen very often) may be able to will a new subatomic particle into existence. A ridiculously overpowered character may be able to hiccup and accidentally tear the very fabric of the space-time continuum asunder. High-end Reality Warpers tend to also be Reality Makers. For the really high end ones, see The Omnipotent.
