Sinister employed the mutant outlaw Gambit to assemble a team of superhuman assassins. Unaware of Sinister's plans for them, Gambit assembled the group now known as the Marauders. Sinister then ordered the Marauders to massacre the underground community of mutants known as the Morlocks.

    Despite opposition by the X-Men, the original X-Factor, and Thor, the Marauders slaughtered enormous numbers of the Morlocks, although a considerable fraction of the Morlock population managed to escape. The X-Men's Colossus, Nightcrawler, and Shadowcat were all seriously injured, and the Marauder Harpoon impaled the Angel's original wings, necessitating their amputation. The Angel has since grown his wings back.

    The Marauders Blockbuster, Prism, and Riptide apparently died in the course of this "Mutant Massacre." However, Sinister apparently creates clones of any Marauders who perish in his service. Hence, the full roster of Marauders was present for their subsequent clashes with the X-Men.

    One of the Marauders, Malice, apparently exists in the form of pure consciousness. She was able to take mental possession of the X-Man Polaris, and battled the X-Men using her as a host body.

    The X-Men encountered the Marauders for the second time when they stopped the assassins from killing Madelyne Pryor. Unknown to the X-Men at that time, Maddie was a clone created by Mister Sinister, who had ordered the Marauders to eliminate her.

    Still later, the Marauders fought the X-Men and the original X-Factor on Mister Sinister's behalf at the time of the demonic invasion of Manhattan known as the "Inferno."

    Since then, there have been no known activities by the Marauders as a team. Apparently Mister Sinister no longer employs them; at one point he even used another team of mutant operatives called the Nasty Boys instead.

    The Marauders have apparently disbanded. Sabretooth went back to operating independently. Polaris regained her free will and is now a member of X-Factor; she and Havok successfully battled Malice recently.

    Arclight and Vertigo briefly served in Superia's Femizons. Apart from those of Sabretooth, the present whereabouts and activities of the other Marauders are unknown.
