Sun Boy (Dirk Morgna) is a superhero appearing in media published by DC Comics, primarily as a member of the Legion of Super-Heroes in the 30th and 31st centuries.

Sun Boy first appeared in 1961 during the Silver Age of Comic Books. Publication history Sun Boy first appeared in Action Comics #276 (as a cameo in a Supergirl story) and was created by Jerry Siegel and Jim Mooney. His first full appearance (albeit as an impostor) is in Adventure Comics #290. Fictional character biography Silver Age 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.
