Reboot
Years later, Mark touched a white light that put him back into his body at the time before he received his powers and with all of his memories. He attempted to talk to his father about not killing the Guardians of the Globe again. Nolan became angry and immediately attacked Mark. Mark led him to Utah where he tricked Nolan into smashing into the Guardians of the Globe headquarters. He revealed Nolan's plans to the Guardians and they subdued Nolan. Cecil Stedmen soon arrived and agreed to bring Nolan back to the Pentagon and restrain him.
