Bruce Gordon was a scientist who was on Diablo Island in the South Pacific to photograph an eclipse. The natives, fearing that he would steal their sun god sent their witch doctor, Mophir to stop him. Armed with the tribe's sacred black stone, Mophir attacked and cut Bruce with the gem, but fell off a cliff. Bruce picked up the gem just in time for the eclipse to take place he and became Eclipso.
Gordon's speciality was solar energy, the one weakness of the God of Vengeance, Eclipso. Eclipso made tried to distract Gordon and ruin his life by using him as his own physical host. Bruce Gordon reluctantly acted as Eclipso's human body for many years.
