MacDonald Gargan (Earth-4678)

MacDonald "Mac" Gargan used to be a run-of-the-mill street criminal and not an especially good one. He later signed up for an untested procedure to fuse his body with a mechanized combat suit, funded by J. Jonah Jameson, in order to combat Spider-Man. The process made Gargan stronger and faster than naturally possible, but also exacberated his rage and aggression. He soon became one of the many villains that Spider-Man defeated and was eventually incarcerated in the Raft, spending years locked away.
