Have you ever noticed how whenever a Superhero is created, a bunch of super-villains appear soon after, and quite often, the hero actively creates the villain… for example:
Batman accidently drops Napier in an acid bath, creating the Joker (I shall ignore the horribly mangled version in the film where napier killed wayne’s parents, thus creating him…)
The only exception to the “Hero first, villain second” rule I can think of is the X-Men, where both heroes and villains turn up more or less simultaneously.
anyway, my question is: Has there ever been a case where the villain came first? In particular, has a villain ever accidentally created a hero?
