Today, EW.com is proud to kick off our Superhero Showdown, bracket game which will allow us to scientifically determine via online reader polls which comic book hero is the greatest superhero ever. The 32 contestants in the bracket mix together well-known media icons with beloved characters from outside the mainstream. That mixture is intentional. Comic book heroes belong to the world now more than ever. (A trio of movies starring comic book characters grossed literal billions of dollars this summer.) Mega-geeks and casual fans are both welcome. To learn more about the Superhero Showdown, watch the introductory video below. Be sure to check out our complete printable bracket, and vote in the first four Day One match-ups here.
