while he lay in prison and shot him at point-blank range with adamantium bullets. The bullets, while not penetrating his skull, did cause severe trauma to his brain, resulting him in needing surgery, but the hospital he was brought to was unable to treat him. In mid-surgery however, men working for the Kingpin's rival Mister Negative came in, killed the hospital staff, and took Hammerhead away. Mister Negative then has his surgeon Doctor Trauma revive Hammerhead and offers to transplant his brain into a new robotic adamantium skeleton, which Hammerhead agrees to. The operation is a complete success, and Hammerhead is restored to full mobility without any ill effects. He swears loyalty to Mister Negative in exchange for his restored life and proceeds to shape a gang of lowlife thugs into an effective army for his benefactor. He then proceeds to battle Spider-Man, besting him with no effort for the first time in years. Later, he has a rematch with Spider-Man, with Spider-Man dislocating Hammerhead's hip bone. Mister Negative sends Hammerhead to help Spider-Man (who Mister Negative corrupted) take down the Hood, who launches an attack on Negative's headquarters. He blackmails H.A.M.M.E.R. director Norman Osborn into forcing the Hood to pull out of Chinatown. Hammerhead later begins to doubt his loyalty to Mister Negative when Silvermane, a deceased former Maggia don and an old enemy of the Kingpin, appears to return. Unknown to Hammerhead, "Silvermane" is actually an android controlled by Mysterio to plant seeds of rebellion. Nevertheless, he flees a shootout with the Maggia when the Silvermane robot calls him a traitor. It is shown that Mister Negative had a computer chip put in Hammerhead's head to deliver an electroshock when necessary, which he promptly uses to punish him and remind him who is in charge. During the Origin of the Species storyline, Hammerhead and Mister Negative are among the supervillains invited by Doctor Octopus to join his supervillain team, promising them that they will receive a reward in exchange for securing some specific items for him. Alongside his nephew and minions, Hammerhead formed an alliance with the Black Cat, where he sided with her gang. Hammerhead is among the crime lords competing with Mister Negative in obtaining the Tablet of Life and Destiny in order to win the favor of Mayor Wilson Fisk. Powers and abilities Hammerhead has no superhuman abilities, yet his skull is now surgically reinforced
