Superman / Batman #1

In "Los Mejores del Mundo," Superman and Batman are forced to join forces when a retooled, enhanced Metallo strikes both Metropolis and Gotham City, pushing the two heroes to confront a threat too great for one to handle alone. With the President assembling a super-team to assist the Man of Steel, tensions rise as the world’s mightiest heroes face a crisis that demands unity—and sacrifice. Written by Jeph Loeb and brought to life by Ed McGuinness’s dynamic art, with inks by Dexter Vines and colors by Dave Stewart, this 2004 milestone features a striking cover by Ed McGuinness and Dexter Vines.
