Ultraman is the name of several supervillains appearing in stories published by DC Comics. The characters are all evil or corrupted alternate-universe counterparts of Superman. Ultraman first appeared in Justice League of America #29 (August 1964). Publication history Ultraman first appeared as the evil counterpart of Superman on the original Earth-Three. Having created the worlds of Earth-One, containing Silver Age superheroes, as well as Earth-Two, containing the Golden Age ones, DC Comics decided to expand the universe to include various themed universes. The first of these was Earth-Three, in which there were villainous counterparts of DC's heroes as well as heroic counterparts of DC's villains. The first Ultraman was killed in Crisis on Infinite Earths and Earth-Three was destroyed by an anti-matter storm and then wiped from continuity at the end of the series. This original Earth-Three Ultraman has reappeared briefly both in the 1980s Animal Man series and the later Infinite Crisis mini-series. Since Crisis on Infinite Earths, DC has returned to the concept of Ultraman, creating two different characters with that name, often appearing only for a single issue in a story arc. There have been several appearances by both characters. The first version was an anti-matter version of Ultraman, created for Grant Morrison's JLA: Earth 2 graphic novel. This version has appeared several times and was slain at the conclusion of the Final Crisis series. Another version, closer to the Silver Age original Ultraman, appeared on the New 52 universe's Earth-3. Based on comments by Grant Morrison, this Earth-3 universe is not the pre-Crisis Earth-Three, making this a new character unrelated to previous versions. Fictional character biography Original Earth-Three Ultraman Unlike Superman, the Earth-Three Ultraman gets stronger every time he is exposed to kryptonite, originally developing a completely new superpower with each new exposure. In one such encounter, Ultraman acquired the ability to see through dimensional barriers, thus alerting the Crime Syndicate to the existence of alternate Earths in their first appearance. This allowed the Syndicate to attack the Justice League and Justice Society. Ultraman also differed from Superman, in that his version of the planet Krypton had not exploded. Where the Earth-Three dimension kryptonite originated was never specifically listed in any published book. However, it is implied to be the same as ordinary kryptonite, as Ultraman got powers when exposed to Kryptonite from pre-Crisis Earth-One and Earth-Two, gaining fire vision from Barry Allen throwing some at
