He might not have the name recognition of the Green Goblin or Doc Ock, but before Spider-Man could face off against them, he had to take on his very first opponent: Crusher Hogan. Appearing for only two pages back in Amazing Fantasy #15, Hogan was a pro wrestler who offered a cash prize to anyone who could last three minutes in the ring against him, and made a perfect foil for Peter Parker to test out his brand new powers. If you've been wondering what happened to him after, though, well… it's not great for him.
In Amazing Spider-Man #271, a story called, fittingly enough, "Whatever Happened to Crusher Hogan?" recast him as a broken down janitor at a boxing gym who told all the rookies that he'd helped train Spider-Man. Unfortunately, he was on the wrong side of Manslaughter Marsdale, a massive, super-strong gangster who was extorting him. When Spider-Man showed up to deal with the supervillain, he also pulled off the babyface move of telling all the other boxers that Hogan actually was the guy who helped him get his start.
A much darker take, however, came in "The Last Shoot," from Spider-Man's Tangled Web #14. Co-written by Brian Azzarello and pro wrestler Scott Levy — better known to wrestling fans by his in-ring name, Raven — this story showed Crusher as the struggling star of an independent wrestling company on the verge of bankruptcy. In a last-ditch effort to make money, Crusher, a "shooter" (a wrestler actually skilled in non-scripted shoot fights), riled up the fans and offered a cash prize to anyone who could beat him. The gimmick worked, and just when things started to look like they were turning around, a masked Peter Parker showed up to try his luck and walk away with the prize. To make matters even worse? It was revealed that Crusher borrowed the money from Hammerhead, a mobster who told him that he'd crush his hand in the trunk of a car if he wasn't able to pay it back. Great responsibility indeed.
