Hellbound Iron Man

In another reality, the worst that could've happened, happened. The Earth was turned into a nightmarish hellscape by Doctor Doom, who became the new Ruler of Hell. With his great power, Doom slaughtered nearly every hero on the planet. Needing an army to enact a hellish takeover of the entire Universe, waging war against the cosmic gods, he would resurrect all of the dead, turning them into his army. One of these being Iron Man. Tony Stark has been long dead, this monstrous husk is only Doom using his body as a puppet and a footsoldier, the powers of Hell and death twisting and contorting his body and armor into something abominable.
