Doctor Light is a DC Comics supervillain and a recurring antagonist of the Teen Titans who first appeared in Justice League of America #12 (June 1962). Arthur Light was a physicist and genius. He used his brilliant mind to construct a suit that gave him the ability to manipulate light in various ways. Some of these abilities include light energy beams, flight, invisibility, energy absorption and can create an energy force field. With his new power, Light had fought the Justice League many times, but he was defeated each time. Later on, he fought the League's sidekicks, the Teen Titans. He even formed the Fearsome Five along with Psimon, Jinx, Gizmo, and Mammoth to fight the Teen Titans, but they were also defeated.
