The man known as Forge was a Cheyenne Indian, once the pupil of Naze, a shaman in his tribe. Forge developed considerable mystical powers as a result of the training Naze gave him and was also a mutant with an unusual talent for inventing mechanical devices. Forge has explained that he was an intuitive genius and it was as natural as breathing for him.
Forge served in the Vietnam War and lost his right hand and right leg in a B-52 attack. During the war, Forge, using the souls of nine dead comrades, had opened a portal that released the Adversary to win a battle. Forge sank into a suicidal depression and tried to kill himself. Forge designed an artificial hand and leg to replace those that he had lost and, for reasons connected with the war that have not yet been made clear, Forge decided to give up the use of his ability to wield magic. For the most part, Forge did not used his mystical abilities for at least ten years.
Forge concentrated instead on his career as an inventor, and when Tony Stark ceased making advanced weaponry for the federal government, the Defense Department began commissioning new weaponry from Forge. The government commissioned Forge to devise a means of detecting and combating the shape-changing alien Dire Wraiths.
Forge created a scanner device that could detect the presence of superhumanly powerful mutants and extraterrestrials in its wielder's vicinity and could even specifically differentiate between Dire Wraiths and other aliens. Forge also created a neutralizer device that could theoretically deprive any superhumanly powerful being the ability to use his or her superhuman abilities.
On presidential orders, Henry Gyrich, an agent of the National Security Council, took possession of the only existing model of Forge's neutralizer in order to use it against Rogue, a member of the mutant X-Men who was falsely suspected of killing an agent of the intelligence organization S.H.I.E.L.D..
Forge was outraged, as the neutralizer was still untested and he did not know if it would remove a target's superhuman powers temporarily, permanently, or possibly even kill him or her. Forge physically attempted to prevent Gyrich from using the device on Rogue, but Gyrich instead shot Rogue's fellow X-Man Storm with it, as she attempted to protect her colleague. With her superhuman powers apparently entirely removed, Storm fell into a river, from which Forge rescued her.
Feeling guilt and responsibility for the loss of her powers, Forge brought Storm to his Eagle Plaza in Dallas, Texas. There Storm revived and she and Forge grew strongly attached to each other. However, when Storm learned that Forge had designed the neutralizer gun that had deprived her of her powers, she felt betrayed.[6] Furious at Forge, Storm left his building, but returned on learning he was in danger from the Dire Wraiths. The Wraiths were aware that Forge's neutralizer could not, in its present stage of development, harm them and intended to kill him before he could improve it.
Together, Naze, Magik, and Amanda Sefton joined with Forge, Storm, and the X-Men in defeating the Wraiths who came after Forge, but Storm's hatred of Forge persisted. Naze faked his demise at the barbed tongue of a Dire Wraith, letting it assume his identity and then fall under the mental control of the Adversary, sparing Naze from this fate. Forge longed for Storm going so far as to create holograms of her in his Eagle Plaza.
Forge further improved his neutralizer so that it would negate the Wraiths' mystical abilities, and created several of these improved devices, but he was still guilt-ridden over Storm's loss of her powers. Fearing that people would use his neutralizers against other superhuman Earth beings, Forge did not want to give them the devices even for use against the Dire Wraiths, but, after joining forces with the Wraiths' greatest foe, the space knight Rom, to battle Wraiths in Dallas, Forge decided to construct a gigantic "neo-neutralizer" in Earth's orbit. Powered by Rom's own neutralizer, Forge's orbiting device could cast all the Dire Wraiths on Earth into other-dimensional Limbo.
Gyrich intended to use the neo-neutralizer to eliminate the superhuman powers of every being on Earth. To thwart Gyrich's plan, Forge and ROM aimed the neo-neutralizer not at Earth, but at the Wraith's homeworld, Wraithworld, which was approaching Earth through hyperspace. The device negated Wraithworld's magic, the source of the Wraiths' own mystical powers; therefore, causing Wraithworld to cease to exist and depriving Wraiths throughout the universe of their mystical abilities. Thus, Forge was responsible for saving Earth from the Dire Wraiths.
Forge ensured that the neo-neutralizer could not be used against Earth's superhuman beings and all known specimens of Forge's neutralizer have been destroyed. One neutralizer was used by Tony Stark to depower the superhuman criminal, known as the Termite, and was subsequently destroyed.
Forge was next seen atop a mountain, seemingly opening a dimensional portal filled with demons. Storm, who had been manipulated by the Adversary in Naze's guise, stabbed Forge in the chest and, only then, realized he had been attempting to close the portal, not open it. The Adversary then trapped Forge and Storm in the other dimension and seized control of Dallas, warping time and space in order to foment chaos on Earth. Forge and Ororo Munroe spent a year on an alternate Earth, during which time they made peace and admitted their love for one another.
After a fight, Ororo left and, upon returning, Forge used components from his cybernetic leg to fashion a new device that restored Storm's ability to use her powers, which she then used to energize a portal back to their own world. Forge and Storm rejoined the X-Men and were captured in the Omniversal Guardian, Roma's, Starlight Citadel, that the Adversary had taken over. Forge was forced to use his mystical abilities again to banish the Adversary, using the souls of eight X-Men and Madelyne Pryor-Summers. However, Roma restored the X-Men to life and freed the Adversary under the notion that there could be no order without chaos.
