Mister Mxyzptlk (2000)

A Loki-ish prankster who uses people's lives as his game pieces. Mxy employs his awesome, five-dimensional reality-warping powers to trap Superman in dangerous, unreal scenarios... a high-stakes upgrade of the Elseworlds concept. No longer content to make buildings sprout wings, Mxy warps the facts of Superman's life in a sustained effort to test and break the Man of Steel's spirit (because the imp's fifth-dimensional intellect rightly understands that Superman's pure soul is his true power). Sometimes aware that he's been thrust into warped histories and sometimes not, Superman can only win these games by rising above the Mxyworlds' temptations to be less virtuous, less positive, less dedicated, less effective than we know he can be. Superman's own inner strength is the key to making Mxy disappear.
