Ultraman (DC)

Ultraman is the name of several DC villains, all of whom are evil-versions of Superman - the current holder of the title is said to be the Superman alternative from the antimatter-universe, as a resident of the antimatter universe he is a devote worshipper of evil and thus in direct opposition to the ideals his mainstream counterpart stands for.

Ultraman is not to be confused with the clone of Superman that went berserk in Superman: Doomsday, though the two are similar concepts Ultraman is defined as the dark-half of Superman made flesh rather than a simple clone-turned-bad - being born in another universe and thus possessing similar powers to the mainstream Superman but used purely for selfish and/or immoral gain.

Ultraman has not been seen very often in publishing outside the comics, though other villainous versions of Superman have - such as the rogue Superman from Justice Lords - however Ultraman himself appeared in the 2010 animated film Justice League: Crisis On Two Earths and also appeared in the DC Universe Online videogame.
