The Ultimen are test tube babies, created in Cadmus laboratories by Emil Hamilton and possessed complete sets of false memories (most likely implanted there by Dr. Hugo Strange, the only member in Cadmus with such knowledge). When Wind Dragon began exhibiting unexpected changes in his powers, Cadmus discovered that the clones were unstable.
After discovering that they were merely the current batch from a perennially doomed experiment of creating superpowered clones with implanted memories, the Ultimen rebelled and went on a rampage against both Cadmus and the Justice League. They were reasoned with by members of the League and stopped their rampage. Long Shadow, who had tried to stop the rampage, left with the Justice League while the remaining members were returned to Cadmus.[1]
With that, the original Ultimen were out of the picture (final fates unkown). It was never revealed if the sentient Ultimen first encountered by the Justice League were able to be saved by Cadmus or the League, in the case of Long Shadow. But in case they did all die from massive cellular degredation (as presumed), the Ultimen died for nothing as caged lab rats in Cadmus captivity while Long Shadow was given a hero's death, nobly giving his life for the honor and glory of the Justice League during his last moments.
