Infinity-Man was a man named Astorr, a powerful warrior from another planet. Astorr came across Drax (Darkseid's brother) who was horribly burnt. After nursing Drax back to health, he died from old age. Before he died, Astorr was able to pass the role of Infinity-Man to Drax. It took Drax years of study before he was ready to assume the title of Infinity-Man. Drax (Infinity-Man) eventually came to serve Highfather on New Genesis, where he was acquainted with The Forever People and became a protector. Whenever Infinity-Man was needed, all the Forever People would touch the mother boxes and recite the word Taaru, thus tossing them into limbo until Infinity-Man returned the power to them.
Darkseid saw Infinity-Man as a threat and figured out a way to place him in another dimension, where Infinity-Man made a planet called Adon his home. The Forever People were able to free him from this prison. Devilance the Pursuer had a personal vendetta against the Forever People and especially the Infinity-Man. Devilance tracked down Infinity-Man and the two battled, which resulted in the island they were fighting on exploding. The two appeared to die, but Infinity-Man returned due to the effort of the Forever People and Maya to defeat Darkseid.
