He married a woman he had saved whose life, named Debbie, and they had a son, Mark Grayson. \[3\] It was later revealed that Nolan had been sent to Earth as a conqueror of the Viltrumite Empire, a revelation that contrasted with his earlier claims that his presence was to advance human technology and protect Earth from extraterrestrial dangers. Shortly after, in a confrontation, Omni-Man beat Mark to death and fled the planet,\[4\] just before leaving he says to the dying Mark, "Why did you force me to do this? You're fighting to be able to see everyone around you die. \[2\] In addition, it is described that Nolan was escaping the solar system for a hard week, he had found a new planet to rule over, hoping to compensate for some of the problem.
