@djjd62,
as for Marvel ripping off DC, again, i don't see it, Batman was one of the few non alien or magical characters for quite a while
* (Green Arrow, the Atom and the Flash were later exceptions), where as the X-men were humans with genetic mutations (the theory is they'd always existed, but the use of the first Atomic bombs had accelerated the the profusion of mutants), Spiderman was a kid who was enhanced by science (radioactive spider), Daredevil was a kid blinded by a radioactive substance which enhanced his other senses, the Fantastic Four were humans who were changed by cosmic rays, Captain America was an enhanced human, not to mention The Avengers, most were scientists or inventors (Hank Pym, Iron Man, Bruce Banner/The Hulk)
not that the Marvel stories or characters are any more realistic or believable, but i don't see much ripping off
*Superman is an alien, Shazam is a magical being, Wonder Woman is a god (or progeny of gods), Green lantern gets his ring from an alien, Martian Manhunter is an alien, Hawkman is a reincarnation of a egyptian prince
