This week, kicked off our official Superhero Showdown bracket game, a 32-way battle to decide which costumed crimefighter is the greatest superhero in comic book history. On today’s episode of Entertainment Geekly, Jeff and I closely analyze all 16 first-round matches and offer our own picks. There are some surprises. There are some heartbreaking decisions. There are occasional tangents into the history of comic books. And there is a surprising outpouring of support for Metamorpho.
