9. ACTION COMICS #785 (2002)Simple yet effective, this cover doesn’t hold back who the main baddie is in this issue. The hulking presence of Superman’s twisted mirror image, Bizarro, is perfectly exaggerated by comic vet Ed McGuinness and showcases the offbeat humor that is to be expected from the backwards talking rogue.
Sometimes the most effective cover is also the simplest. And if the character is popular enough, that’s really all you need to show. In a time when comic writers and artists seem to be competing with each other over how much grittiness they can fit on the page, this cartoonish cover is the perfect example of how much fun a comic can be.
