In the alternate 31st century of the original Guardians of the Galaxy, designated as Earth-691, Doom is revealed to have somehow managed to place his brain inside the adamantium skeleton of Wolverine at some unknown point in the past, hiding this fact with a perfect replica of his original armor, cloak, hood, and simulated flesh intended to give the appearance that he has managed to prolong his life to unnatural lengths. He eventually comes face to face with Rancor, a descendant of Wolverine, and offers to become her ally, though he secretly intended to use her as a pawn for his own gain, while she intends to slay him on her quest to determine what happened to Wolverine. During their battle, Doom reveals himself to be in control of Wolverine's skeleton, heavily modified with cybernetics and missing half of one of the claws, which had eventually come into the possession of Rancor. Rancor manages to strike at one of Doom's robotic eyes, forcing him to retreat. Doom is not seen again in this reality.
