Poor Gibbon. All he wants is for someone to like him and be a super-hero. He catches up with Spidey and asks the wallcrawler to be his assistant. When Spider-Man laughs because he wasn't sure the guy in the gorilla suit was serious, Gibbon quickly becomes Spidey's next go-round!
First appearance of Gibbon.
