Ralph Roberts was an inventor who had been studying the effects of nuclear radiation involving cobalt. He sought to use this as a weapon and built a cobalt suit of armor in imitation of Iron Man's, and called himself the Cobalt Man. At the time, Ralph's younger brother Ted Roberts was dating Jean Grey. Ralph Roberts took Ted, Jean, and Scott Summers on a tour of his lab, and when he showed Ted his armor he became destructive, and when Scott and Jean fought the Cobalt Man he buried them under rubble. As he was becoming more unstable, the X-Men fought and defeated him, and he realized that the armor was too dangerous to use. However, Tyrannus soon kidnapped him to force him to build a giant super-cobalt robot. The X-Men fought Tyrannus and rescued Roberts and returned him to the surface world.
He later achieved superhuman size and power due to radiation. This ends up slowly killing him; addled, he decides to show the world the dangers of nuclear power by destroying himself and the city of Sydney, Australia. In a confrontation with the Hulk, he seemingly dies, safely away from the Earth. While on a mission with Egghead's Emissaries of Evil, he appeared to have been killed in a nuclear explosion.
