Crisis on Infinite Earths

Published from 1985 to 1986, 'Crisis on Infinite Earths' was a landmark crossover event by DC Comics, written by Marv Wolfman with art by George Pérez. This 12-issue series was designed to streamline the complex DC Universe, which had become convoluted due to numerous alternate realities and timelines. The story follows the villainous Anti-Monitor, who seeks to destroy all positive matter universes, and the Monitor, who assembles a team of heroes from across the multiverse to stop him. Key characters include Superman, Batman, Wonder Woman, and The Flash, among many others. Major events include the deaths of Supergirl and Barry Allen (The Flash), and the merging of multiple Earths into a single universe, effectively rebooting the DC Universe. The series had a profound impact on DC Comics' continuity, setting the stage for future storylines and simplifying the multiverse concept. It was critically acclaimed for its ambitious scope and is considered a seminal work in comic book history.
