Fan Casting Hammerhead in The Ultimate Spider-Man: Animated Series (Season 1) (2012)

Joseph Lorenzini or better known as Hammerhead is a ruthless yet trustworthy criminal in the Maggia who works as an assistant hired by Silvio Manfredi or Silvermane and will do all of the tasks he has been assigned for including torturing the kidnapped hostages and to assassinate Spider-Man as his boss wants the superhero dead using nothing but his brutal strength and a tommy gun as his own weapon in order to make his master and the rest of the Maggia proud and eventually pay him a good amount of money for him to possibly start a new criminal empire for himself. The real reason why he got that nickname was because his notable feature is obviously his head being large yet strong due to a genetic disorder he has been born with and will use his own head to aggressively knock anyone out which may make him feel mentally unstable but would also make him feel like a superior individual nobody wants to mess with as well.
