Hammerhead is a supervillain appearing in American comic books published by Marvel Comics. Created by Gerry Conway and John Romita Sr., the character first appeared in The Amazing Spider-Man #113 (October 1972) and has since endured as a recurring adversary of the superhero Spider-Man.
Hammerhead is typically portrayed as a stereotypical mobster who dresses and speaks in a 1920s style. He is known for his short temper and for his affiliation with the Maggia, a fictional organized crime syndicate similar to the real-life Mafia. His nickname stems from the steel alloy that replaced most of his skull after a failed murder attempt, giving his head a flat shape and near-indestructibility. The Hammerhead crime family, of which he is the second and current head, is named after the character.
As a well-known enemy of Spider-Man, the character has appeared in several media adaptations, including animated series and video games. In 2014, IGN ranked Hammerhead as Spider-Man's 20th greatest enemy.

Publication history
Hammerhead made his first appearance in The Amazing Spider-Man #113 (October 1972), and was created by writer Gerry Conway and artist John Romita Sr.
Conway recalled that Hammerhead "was most directly influenced by the Big Man and the Crime-Master, who were among the first villains in Amazing Spider-Man. One of the more interesting things Stan [Lee], Jack Kirby, and, of course, Steve Ditko did was combining the two different kinds of milieus: superhero and Dick Tracy, with the unusual criminal characters who had some kind of physical deformity... Plus, Hammerhead—I liked [the] name, and John Romita came up with an interesting look".
Fictional character biography
Hammerhead's family immigrated from the Soviet Union to Italy when he was a child with help from a man known only as the General. His father ran a garage in Toirrano, where he insisted the young man speak only in Russian, beating him severely with a mallet when he would not. Although not much is known about his life before he became a criminal and supervillain, Hammerhead is known to be married and has a sister named Antonia.
All the while, Hammerhead dreamed of becoming a gangster. He is eventually recruited into one of the "families" of the criminal organization known as the Maggia when a member oversees Hammerhead "making his bones" by murdering a childhood bully and his girlfriend in a theater showing The Godfather Part II. Originally a small-time hitman, Hammerhead quickly rises through the ranks of the Maggia, while pretending to be ethnically Italian so he can be "made". In his final test, Hammerhead is brought to his father's garage (with the Maggia apparently unaware of their relationship). Hammerhead proceeds to kill his father, while saying in Russian that he blames his villainy on his father's abuse.
One day, Hammerhead was found beaten, disfigured, and delirious with pain in an alley in New York City's Bowery by Jonas Harrow, a surgeon who had lost his medical license due to his illegal experiments. Seeing the opportunity both to save this man's life and to redeem his reputation, Harrow operated on the gunman for three days, replacing much of his shattered skull with a strong steel alloy. During the surgery, the unconscious thug fixated on the only memory he retained: an image of a poster for a movie called "The Al Capone Mob", which was hanging in the alley where he lay beaten and bloodied before Harrow found him. When he recovered, the memory of the poster and its images of 1930s-era gangsters prompted Hammerhead to start a gang of his own in the style of Capone and other mobsters of the 1920s. He even dressed as if he were living in that decade.
A gang war broke out between Hammerhead's mob and Doctor Octopus's criminal organization. Hammerhead was forced to flee the country due to Spider-Man's interference. He later had a rematch with Doctor Octopus next to an atomic breeder reactor on a remote Canadian island which caused a chain reaction, blasting Hammerhead "out of phase" with this dimension. Some time later, he appeared as an immaterial ghost-like being to haunt Doctor Octopus. Doctor Octopus then unwittingly used a particle accelerator to restore Hammerhead to his corporeal form. Hammerhead kidnapped Spider-Man's Aunt May, who was then rescued by Spider-Man as Doctor Octopus caused Hammerhead's helicopter to plummet into the Hudson River.
Powers and abilities
Hammerhead has no superhuman abilities, yet his skull is now surgically reinforced with vibranium (or secondary adamantium), making his head flat on top; with this, he can charge and break through objects such as brick walls without causing any pain or damage to himself. This metal can absorb physical impacts that would otherwise fracture human bone. Hammerhead is in peak physical condition comparable to that of an Olympic-level athlete. He is a formidable hand-to-hand combatant whose most dangerous tactic is charging head first like a bull toward an opponent. Hammerhead once utilized a strength-enhancing exoskeleton designed by the Tinkerer.
After an assassin's adamantium bullet penetrated a part of his head not protected by his adamantium skull, Hammerhead is surgically rebuilt by Mister Negative. Breakout surgeries replace the upper half of his skeleton with an adamantium endo-skeleton (the skeleton is shown to have a network of hydraulic servomechanisms). The upper portion of his body is now superhumanly strong as a result of the additional hidden cybernetic musculature, making him able to effortlessly beat a superpowered foe such as Spider-Man. Mister Negative does not use on Hammerhead the same Lord Dark Wind bonding process, used on the similarly empowered Wolverine and Lady Deathstrike for coating their bones in adamantium: instead he replaces Hammerhead's bones with replicas fashioned in the invulnerable metal. It is still unknown how his artificial skeleton can carry on biological functions.
The intervention of Mr. Negative also radically changed Hammerhead's personality. Hammerhead now recalls his life as a Russian immigrant prior to the accident in which he adopted the 1920s gangster persona. Consequently, Hammerhead no longer speaks like a 1920s gangster, but instead behaves as a typical modern Russian mobster and hitman, as this was apparently his original personality prior to his head injury.
Hammerhead is highly skilled in the organization, concealment and management of criminal enterprises. He is an effective hitman, a skilled marksman (his preferred weapon was the Thompson submachine gun), and an excellent street fighter. In his original incarnation, Hammerhead was able to hold his own against Spider-Man despite being an ordinary human by using his superhumanly durable skull as a blunt instrument. After his recent augmentation, he is now capable of grappling with and physically overpowering Spider-Man to the extent that he could eventually crush his foe.
