Scalphunter

John Greycrow was a Native American from an unidentified tribe who fought in World War II for the United States of America, but was executed for murdering his fellow officers. He was shot by a firing squad and was believed killed. However, because of his regenerative powers he survived and became a mercenary. Decades later, he worked at a diner in Millstone, Arizona with Remy LeBeau and Claire DeLuc. LeBeau later recruited him to join the Marauders on behalf of Mr. Sinister.

Scalphunter became a member of the Marauders, a band of assassins who were gathered together by the mutant thief Gambit at the request of the enigmatic mastermind known as Mister Sinister.

For their first mission, the Marauders were tasked with the assassination of Sinister's former pawn Madelyne Pryor. Sinister had formerly erased any proof of her existence. Along with Arclight, Scalphunter posed as a paramedic while Madelyn was the sole survivor of a plane crash in San Francisco. She tried to escape but was hunted by Scalphunter, Arclight, Prism, and Harpoon, and was eventually shot by Scalphunter and left for dead, only for her to recover in a hospital.

Scalphunter later appeared revived, presumably resurrected by the Five, and accepted Xavier's invitation to all mutants to join the nation of Krakoa. Being the only Marauder to join the island, however, he quickly fell into trouble after engaging in a shootout with multiple Morlocks, who sought revenge on him for his actions of the Mutant Massacre on the anniversary of the event. As punishment, Scalphunter was placed on a new iteration of the Hellions led by Mister Sinister, as a chance for rehabilitation, with their first job to capture Greycrow's ex-teammates in the Marauders who refused to come to the island. Scalphunter took the job of handling a feral Wild Child on missions.

During their first mission, he was captured along with Nanny and Orphan-Maker while the others were off battling the rest of the Marauders and Goblyn Queen. While being cut open by a decaying, perverse Arclight, he was saved by his teammates Wild Child and Psylocke, and Havok, who blew up the house, defeated the rest of the Marauders.

John, after the mission, was seen enjoying himself at the Krakoan shore and was visited by Wild Child and Psylocke.

He and Empath share a mutual hatred for each other.
