1. Superman vs. Muhammad Ali
Come on, you KNEW this had to be number one. Of course it is.
After Ali’s tragic passing last week, I really wanted to give this one a re-read, and once I did, I wanted to find an excuse to write about it. Not only is Superman vs Muhammad Ali an amazing comic in its own right, it’s also a loving tribute to both of its title characters.
In the story, an alien overlord comes to earth to abduct earth’s greatest fighter. Superman and Ali argue over who exactly that is, so the aliens abduct them both and make them fight. Supes is under red sun radiation to make it a fair fight, so of course Ali kicks his butt.
While Clark sneaks around the spaceship, searching for a way to take out the aliens, Ali is pitted against the greatest alien champion. After a tough fight and some wonderful monologuing, Ali wins and single handedly topples the alien government by being awesome.
They return to earth and Ali reveals that he almost immediately figured out that Clark Kent and Superman are the same dude but he won’t tell anyone because he’s the perfect person.
Ali was the greatest, so it’s fitting that his comic book appearance would be as well.
