The Green Man was born on the planet Uxor, circling a star 52 light years from Earth in roughly the same direction as Vega. His race evolved on their water soaked world from amphibious ancestors, and they still possess small gills beneath the lower jaw to allow breathing underwater.

The Green Man's race has developed a communal society where group goals are streesed and individuality is scorned. The Uxorans take no personal possessions, not even a name. They are called by the life-task to which they are assigned,and identify each other by their distinctive skin patterns. The Green man was a misfit who longed for personal identity, and when he was approached by the Guardians of the Universe he took the name of Green Lantern with pride.

The Green Lantern successfully patrolled his space sector for a number of yeaars, learning much from his encounters with evil. At length his space sector was infiltrated by the notorious Spider Guild, and though he defeated individual attacks by them several times, they gained a foothold even the help of the other Corps members could not dislodge. Seeing that the Spider Guild was continuing its incursions into the Vegan Star system, the Green Man secretly travelled there to find allies, disobeying a non interference pact between the Guardians of the Universe and the Psions of that region.

Meeting Kalista and other Omegans on the planet Rashashoon, the Green Man convinced them to return with him. Together they destroyed the Spider Guild Nest that seemed to be directing the Vegan attack.

When the Guardians noted what he had done, they reprimanded the Green Man, ordering him not to reenter Vegan space. When the time came to part from his allies, they were in such peril that he could not in good conscience leave them. He decided to stay with the Omega Men and offered any help he could without using his power ring. Soon after, the group was captured by the Psions, and the Uxoran's ring and power battery were confiscated. These actions caused this Green Lantern to give up the name and he asked his friends to call him Green Man instead.
