Captain Spider [Flash Thompson]; the Chameleon; Crusher Hogan (wrestler); J. Jonah Jameson; Spider-Girl [Betty Brant]; Spider Jameson [Colonel John Jameson]; Spider-Man [Peter Parker]; the Tinkerer; the Vulture; the Watcher
What would have happened if someone else had gotten spider powers instead of Peter Parker? Flash Thompson would have named himself Captain Spider and then died in a battle against the Vulture. Betty Brant would have become Spider-Girl, but then retired after failing to stop the thief who murdered Peter's uncle Ben. John Jameson, goaded on by his father, would have become Spider Jameson and then sacrificed his life to save the life of a fellow astronaut. In all these alternate realities, Peter Parker still becomes Spider-Man in the end, as this is his true destiny.
