Reality Warping

Superman has absolutely no resistance to the formidable and virtually unlimited power of reality warping.
By its very nature, it can alter anything in existence to suit the wielder’s needs and, while Superman has never physically been effected by it before (i.e. nobody has ever turned him into a teapot or anything like that), he has been a victim of its consequences, such as in the Emperor Joker story arc, when he found himself in a completely altered universe.
The most powerful reality warpers can change things on a cosmic scale and, unlike some characters in fiction (like Marvel’s Thanos and Doctor Doom, for example), Superman has never shown any resistance to it.
Characters who wield such power include Mister Mxyzptlk (who is so powerful that he does regularly toy with Superman), Lucifer Morningstar and Vyndktvx – all of whom could remove Superman from existence with a mere thought, if they wished.
