So only one mythological character is allowed to exist? Or only one schmuck in a power suit? Or just one alien outlaw? In the entire fucking universe? There's suspension of disbelief, and there's just plain stupid logic.

I'm pretty sure this is not the intention. I believe its just for people to be different players and not be the same kind (or a heavy majority) of a certain kind of character. I believe it's just for the beginning of the part anyways, and there may be more room for these characters in the future.
