History:
Dr. Arthur Light, a physicist, long intended to use his scientific talents for crime. He got his chance after he invented a device that he hoped would enable him to view the future. Instead, he discovered that it allowed him to see what was happening on other planets. Moreover, when he focused on an optics laboratory on the planet Thanagar, he found that the screen had somehow come to act as the focal point of a space warp. Light passed through the screen, looted the Thanagarian laboratory, and returned the way he had come. He modified the stolen equipment to serve his purposes and, armed with his own discoveries, began his career as the costumed criminal Doctor Light. A Thanagarian lawman came to Earth, fought Light, and recovered the stolen equipment, but Light escaped.

Doctor Light next attempted to defeat the entire Justice League of America at once by hunting them into otherdimensional worlds where he thought they would be trapped. The Leaguers, however, escaped and imprisoned Light. Over the following years Light primarily devoted himself to attempts to defeat individual Justice League members, failing each time. Finally, he formed his own group of super-villains, the Fearsome Five. Yet, not only was this team continually thwarted by the Teen Titans, but Light was also unable to resists challenges to his leadership from one of the team members, Psimon.

Weary of his many failures, Doctor Light has given up his life of crime. A new individual using his name has since appeared.

Powers:
Through his own discoveries and through his studies of Thanagarian scientific equipment, Doctor Light created a large number of highly advanced weapons based on the various properties of light. For example, he could fire a beam of "solid light" that had the effect of a battering ram. He could use light to create sapce and dimension warps. He could create highly convincing optical illusions. Doctor Light even discovered a means of walking on light. Although Doctor Light originally used hand weaponry, he eventually incorporated his devices into his costume.

Doctor Light has no superhuman powers but relies entirely on his weaponry.
