This FREE special edition of SUPERMAN/BATMAN #1 by best-selling author Jeph Loeb celebrates the premiere of Batman v Superman: Dawn of Justice, in theaters March 25, 2016.
After a quick origin recap of our world's finest heroes, a new, improved Metallo has come on his birthday to attack both Metropolis and Gotham, bringing the guardians of each city together for a monumental battle! Plus, Lex Luthor assembles a mysterious super-team assigned to "help" the Man of Steel.
It's pretty good. Take a look, and can't beat free!
