Pre-Crisis

Pre-Crisis Ultraman

Origin

Kel Li came to Earth from Krypton, which had not been destroyed, to Centropolis. When exposed to kryptonite as he grew up, he was not weakened like Superman, but instead gained new powers or strengthens existing ones. Adopting the name Ultraman, he decided to use his powers to conquer the Earth. Along the way, he encountered other powerful beings; Superwoman, Johnny Quick, Owlman and Power Ring who banded together to better dominate their world.

Extra-Dimensional Battles

Ultraman developed the ability to see into other dimensions, from his exposure to Kryptonite. Having largely conquered his world, he wanted to test his might against the beings of Earth 1 and 2. The combined strength of both the Justice League and the Justice Society was to much for the Crime Syndicate and they were imprisoned in Earth 1 by Green Lantern.

They would escape their imprisonment a number of times over the years and seek their revenge. Sometimes they would find allies in Earth 1 and 2's Lex Luthor to assist them.

Post-Crisis

Post-Crisis Ultraman

This Ultraman was a human astronaut named Lieutenant Clark Kent. After his shuttle crashed, an alien race reconstructed him with powers similar to Superman, though he needs to be near a substance named anti-kryptonite to sustain them. The process is believed to have also twisted his mind.

Earth 2

Ultraman fights the Martian Manhunter

The Justice League received a call for help from a desperate Alexander Luthor. The only hero in a dark world dominated by the Syndicate and the megalomaniac Ultraman. This Ultraman married Superwoman in their human guises of Clark Kent and Lois Lane, who still had an affair with Owlman despite the risk if Ultraman found out. In fact, it was suggested that he may know.

When the Justice League arrived on their Earth, the Crime Syndicate switched places. Both teams found that they could not succeed in the other universe. Ultraman learned this the hard way when he fought the Martian Manhunter who had remained behind wth Aquaman.

Kandor

Ultraman was discovered in the bottle city of Kandor by Power Girl and Supergirl. He was bought there by Saturn Queento imitate Superman. Which version of Ultraman this is was not revealed. They ruled harshly, especially for the city's alien population.

52

Little has been revealed as yet, but a reborn Earth 3 appears in the pages of 52. According to writer Grant Morrison, this version is not linked to any previous incarnation of the character.

Crime Sociey and Monarch's Army

The reborn Earth-3's Crime Society was recruited by Monarch to join his army. Ultraman often thought he should be second in command of the army but Lord Havok pointed out that it was he who had the brains and experience to lead, not Ultraman. Ultraman sometimes questioned Havok's decisions but followed his orders anyway. During the battle on Earth-51, Ultraman spotted the Challengers From Beyond and punched a hole in the back of the Earth-51 Batman's head. Kyle Rayner used the power of his ring to toss Ultraman away from the area. When Monarch's suit was ripped open during his battle with Superman Prime, a giant nuclear blast went off and blew up the 51 universe. Ultraman and the Crime Socieys' status are unknown at the moment.
