The birth of SpiderMan
When we first met SpiderMan in Amazing Fantasy #15, he was just plain Peter Parker, an unpopular high school student. He was lonely and more interested in books than saving anything or anyone. However, due to the timely interference of a radioactive spider, Peter Parker gains the agility and strength of a spider. Armed with this newfound power, Peter Parker sews himself a red body suit (thank goodness for home economics), constructs a crude webbing device, and joins the professional wrestling circuit to make some money. Alas, Peter Parker is far more into making money with his new skills that helping anyone. When he lets some thieves get away, they end up killing his uncle, setting the stage for the guilt that will drive SpiderMan through the rest of his career.
SpiderMan: the comic books
SpiderMan was written to be a one-time affair. His appearance in Amazing Fantasy, however, resurrected sagging sale, in fact, SpiderMan proved to be one of Marvel's most profitable superheroes. Far from being a one-time affair, Spider-Man can now be found in an endless array of comic books series, from The Amazing Spider-Man, to Spectacular SpiderMan, Sensational SpiderMan, and even Ultimate SpiderMan (not to be confused, of course, with Spide-Man Unlimited).
