A Doctor Doom from an alternate reality has gone by the name of Doom Supreme and is the master of the darkest arts. He used to love a woman named Valeria so much that when she died, he removed the flesh from her bones and forged it with an armor through the power of sacrifice which he also did the same thing when he tortured anyone who defied him when he became his world's Sorcerer Supreme. To power his armor, Doom Supreme went after some alternate versions of himself and sacrificed them while intimidating others like a giant Doctor Doom to swear their allegiance to him. He has described himself as "the Doom who breaks other Dooms".
