The Morlock Massacre Harpoon is a founding member of the Marauders, which were assembled by
Gambit. The team ambush a
Morlock girl named
Tommy and a human
Hellfire Club soldier named Richard in Los Angeles. The Marauders kill Richard and let Tommy escape to the Morlocks' Alley. In the first encounter with the X-Men during the
Morlock Massacre, Harpoon hurls a harpoon at
Rogue while she is vulnerable after having her powers neutralized by the Marauder
Scrambler.
Kitty Pryde phases Rogue, hoping Harpoon's weapon will pass harmlessly through her, but the spear is in an energy state and strikes them anyway, trapping Kitty in her intangible state. Harpoon crosses paths with
Cyclops,
Beast, and
Iceman and tries to kill the Morlock
Plague with
Sabretooth, but they are stopped by
Apocalypse, who recruits Plague into his
Horsemen. He and
Blockbuster later attack the X-Man
Angel, badly damaging his wings. Angel is saved by
Thor, who drives the Marauders off.
Further appearances Harpoon is thought to have been killed during the "
Inferno" event, but as often shown, Mister Sinister can clone his Marauders and resurrect them at any time. Harpoon often works as Sinister's enforcer, such as in the capture of
Nate Grey during the
Onslaught crossover. Harpoon lost his powers after the events of "
Decimation". After M-Day, Harpoon resurfaces with the rest of the Marauders, still working for Mister Sinister. To make up for his lack of power, he carries a weaponized harpoon. Harpoon attacks
Chamber and the X-Men alongside the other Marauders. Chamber manages to kill the Marauders with his fire, but Harpoon stabs him through the chest before dying. Chamber dies from his injuries shortly afterward. ==Powers and abilities==
