Not much has been revealed about the past and early life of the mutant Gideon, including the events that led him to believe himself an External, an immortal mutant. Gideon studied at Harvard but was expelled under circumstances to be revealed. He went on to build his company, Ophrah Industries, into a corporate giant, intending to use his ever-growing financial power to dominate the world.
Later Gideon began forging alliances between hi-tech industrial consortiums such as GeneTech and the Taylor Foundation with powerful mutants or secret organizations such as AIM. He is known to have formed an alliance with the villainous Toad, who was leading the Brotherhood of Evil Mutants at the time, in a scheme to recreate the menace Proteus. Similarly, he joined a group of hedonists known as the Upstarts, although whether or not he carried through with their goals of killing mutants is unknown.
