During Comic Book Men Episode 3, "Commercial", Kevin Smith and the men of the Secret Stash debated which comic book character would be the most fun to have a drink with. But they have yet to weigh in on the mother of all super-questions: Who is the mightiest superhero of all time? You can make your own choice right now with a tournament pitting the greatest superheroes against each other. Is the Hulk's strength any match for Batman's arsenal of weapons? How do Iron Man's defenses compare to Superman's? Could Elektra put an end to Catwoman's nine lives? It's time for you to choose who would win if the defenders of justice did battle against one another.

Don't miss an all-new episode of Comic Book Men, "Zombies," premiering this Sunday at 10/9c.
