Sugar Man is a fictional character, a mutant villain appearing in the Marvel Comics universe. Created by writer Scott Lobdel and artist Chris Bachalo, he first appeared in Generation Next #2 (1995).

Sugar Man initially appeared during the Age of Apocalypse, an event which caused the history of the Marvel Universe to diverge from its usual path. Although many Age of Apocalypse characters were alternate versions of existing heroes and villains, Sugar Man does not appear to have an Earth-616 counterpart.

Sugar Man is originally from an alternate timeline in which Apocalypse conquered North America and mutants ruled. Sugar Man ran the human work camps in the Pacific Northwest - specifically the Core - housing thousands of humans. Magneto needed a mutant with chrono-variant powers—time travel—in order to go back in time and restore reality to its proper order before the death of Charles Xavier, whose existence was revealed by the displaced mutant Bishop. Apocalypse had ruthlessly killed all mutants with that power to prevent anyone from undermining his regime, but Know-It-All found one with latent powers: Illyana Rasputin, the sister of Generation Next's leader Colossus.

Magneto sent the fledgling group to the Core to rescue her. Sugar Man eventually encountered the group and killed several of the members himself, including Vincente and Mondo. Illyana's successful rescue costs all of the young members their lives (except for Husk which was not revealed until the revisit to the AOA reality called X-Men: Age of Apocalypse). Sugar Man was seemingly destroyed; however he had lost most of his mass during the attack and had shrunk to a minuscule size. Hidden in Colossus' boot, he accompanied Illyana, Colossus, Shadowcat, and the X-Men in their assault on Apocalypse's citadel.

Sugar Man has not been a contender in any CBUB matches.
