I remember reading an issue of a Spider-Man series that had Spidey fighting a villain in a white costume with black spots. The spots were actually a kind of portal, which meant that the villain couldn't be hit there. He could also detach the portals and throw them at Spider-Man, then punch through another portal to have his fist come out from the portal near Spider-Man's head and hit him. He was defeated after picking too many portals from his costume, which meant that Spidey had more surface to hit the villain.
I read this in Dutch in the early '80s, but it was at the barber, so it may have been an older issue — he had a stack.
Does anyone know which issue this was (either English original or Dutch translation)?
