Originating from the planet Colutaa, Galan Dox is an alien deity better known as Galactiac. He eats worlds to feed himself but leaves a section unharmed to study. After discovering the planet Earth, he planned to preserve New York City. Galactiac found his mission hampered by many members of S.T.A.R Labs, and he disposed of the Four-Armed Thing and Johnny Stormtrooper. However, he is in turn defeated by the Challengers of the Fantastic and the Silver Racer. Galactiac leaves Earth swearing vengeance.
Being one with the "Power Cosmic", Galactiac possesses superhuman strength, physical resistance, telepathy, telekinesis, and the ability to manipulate energy derived from his cybernetic form.
