When I think about superheroes wearing capes, I immediately think of the DC Comics characters. Heroes such as Batman, Superman, the Spectre, Shazam!, and many more of the Justice League/Justice Society wear capes.
However, when Stan Lee was cocreating the Marvel universe he used the idea of that and flipped it upside down. Stan wanted his villains to wear the capes to rival what DC had created. So when characters like Loki, Magneto, and Doctor Doom were being created Stan was insisting they wear capes. Stan's Marvel Heroes didn't wear capes except Thor.
I have always been more of a Marvel fan than DC Comics fan, but when I think of caped characters it is the heroes that stand out. Batman, Superman, and Spawn immediately come to mind before anyone else.
