Description
Xemnu was one of several inmates on an "exile world" until he snuck past several guards and onto a supply ship. The hijacked craft was only capable of bearing him half of the way home, however, and he was forced to crash land on Earth. There his unconscious, nonoperational body was found in Blacktree Swamp by electrician Joe Harper. Hopeful that he could revive Xemnu by repairing his cybernetic parts, Harper brought Xemnu's body to his workshop. There he revived Xemnu through an electrolysis process. While recharging, Xemnu revealed that he was a convict and then used his hypnosis rays to take control of Harper. After confirming that his hypnosis did in fact work on humans, Xemnu brought Harper out of his trance and revealed his plan to enthrall all of humanity in order to construct a new ship, capable of bearing him home. The force needed to launch the ship would cause a chain of geological events which would tear the Earth apart. As Harper was the one who revived Xemnu, he was to be taken along and spared the fate of the rest of his planet (though Harper suspected that he just liked having someone to gloat over and boast to). Xemnu enthralled the entire human race with his hypnosis rays, and order them to design and construct his new spacecraft. Joe Harper was able to save the Earth by sabotaging the craft: when Xemnu prepared to depart, two crossed wires caused a short circuit which locked him in a state of shock. Harper then launched the craft with only a fraction of the power Xemnu intended, sending him into orbit around the sun. When Xemnu traveled past the Earth's atmosphere, the effects of his hypnosis rays ended, and only Joe remembered Xemnu had ever appeared.
