During the "Five Year Gap" following the Magic Wars, Sun Boy becomes leader of the Legion amidst a series of defections which results in his resignation. Soon afterwards, Sun Boy is hired by Earthgov as a public relations liaison, using his good looks and popularity to spin public opinion. Earthgov is revealed to be under Dominator control and Dirk complies with their demands despite personal misgivings. When the truth is revealed, he is branded a traitor to the Legion and Earth. Dirk is later exposed to a fatal dose of radiation when a powersphere explodes next to him during the destruction of the Moon. He is killed by his sometime lover Circe, in an act of euthanasia. His corpse is later animated for a short time by former teammate Wildfire.
