Looking for a younger version of the character.

Hammerhead is a fictional supervillain appearing in American comic books published by Marvel Comics. The character is usually depicted as an adversary of the superhero Spider-Man. He is a temperamental mobster who often dresses and acts in the 1920s style, and a prominent member of the Maggia, a fictional organized crime syndicate. Following an accident, he had most of his skull replaced with an inflexible steel alloy by Jonas Harrow, giving his head a flattened shape and near-indestructibility, hence his nickname. The Hammerhead crime family, of which he is the second and current head of, is named after the character.

Hammerhead has made appearances in several forms of media outside of comics, including animated series and video games. IGN ranked him as Spider-Man's 20th greatest enemy.
