Hulk fights Conan.
OK, not really. It’s “Kronak the Barbarian.” But this is clearly an attempt to get readers interested in reading about a shirtless, sword-wielding barbarian at a time when Marvel was launching a Conan comic.
This happens as Hulk continues to shrink, smaller and smaller, and he reaches a subatomic world that looks like Conan’s.
