Sun Boy aka Dirk Morgna was born on Earth to a rich and privileged life. However, Morgna developed insecurities and believed everyone was constantly judging him. He was taught by his father in the art of an eye for an eye, to return in kind any slights. Morgna was assigned by his father to do occassional jobs in one of his employees' labs, Dr. Zaxton Regulus. The two often clashed. Morgna happened to ignore warning signs and disrupted one of Regulus' illegal experiments. Out of spite, Regulus locked him in a nuclear reactor. The resulting radiation gave the power to radiate light.

Morgna was persuaded by his parents, staunch supporters of the Legion of Superheroes, to apply for membership. The Legion turned him down when it appeared all he did was radiate. He reapplied after discovering he could focus heat into blasts. Morgna was accepted as the ninth member and took the codename Sun Boy.

Sun Boy can internally generate a seemingly limitless amount of electromagnetic radiation, both heat and visible light. He is also immune to virtually all forms of heat and radiation


Sun Boy's power to radiate light and heat can be reflected back on him by mirrors, jewels and creatures that are reflective. If he increases his radiating power to full strength he can crack mirrors in these situations. One limit to his power is that he cannot risk melting metal in proximity to any persons, since the intense heat required would be lethal.


  • Legion Flight Ring: Like all Legionaries Sun Boy wears a flight ring. It allows him self propelled flight and protection in the vacuum of space.
