Sun Boy is a superhero in the 30th and 31st centuries of the DC Comics universe. Sun Boy (real name Dirk Morgna of the planet Earth) is a Legion of Super-Heroes member with the ability to unleash internal solar energy to whatever degree he wishes, from enough to light a single candle to enough to incinerate a planet. Sun Boy first appeared in 1961 during the Silver Age of Comic Books. Dirk Morgna's father owns a nuclear power plant, where Dirk works as a helper. While he is delivering supplies to one of the plant's scientists, Dr. Zaxton Regulus, the machine the scientist is working on explodes resulting in the death of fellow worker Zarl Hendricks. Dr. Regulus blames the accident, and his subsequent dismissal, on the interruption. He tries to gain revenge on Dirk by throwing him in an atomic reactor; however, due to Dirk's "one-in-a-million genetic structure" instead of killing him, the radiation gives him the power to generate heat and light. Dirk applies for the Legion, as Sun Boy, but is rejected as he has only demonstrated his ability to generate light. He is later accepted when he shows his heat-generation ability. 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.
