Superboy, Earth 2 Huntress, and Weaponer of Qward. Legacy Though it was not the first large-scale comic book crossover, Crisis on Infinite Earths is generally credited with popularizing the idea. Comics historian Matthew K. Manning wrote that Crisis on Infinite Earths paved way for all future crossovers of similar scale, and Andrew J. Friedenthal said "Crisis showed the two major superhero comic book publishers (DC Comics and Marvel Comics) how they could utilize the continuity established by decades' worth of stories to weave together a cohesive, metatextual tapestry that both appealed to long-time readers and brought in massive amounts of money". The series' success inspired DC to begin a tradition of "summer crossovers"; some of these include Invasion! (1988–1989), Armageddon 2001 (1991), Zero Hour: Crisis in Time! (1994), and Identity Crisis (2004), and some mention the events of Crisis on Infinite Earths. The second part of one of DC's later crossovers, Convergence (2015), heavily references the series and sees DC's superheroes travel back to its era. The writers of Convergence all had fun writing stories set during Crisis on Infinite Earths, calling the series an exciting time for DC. The series had an immediate effect on DC, dividing the company's history into two eras: "Pre-Crisis" and "Post-Crisis". Wolfman and Pérez teamed again to produce the History of the DC Universe limited series to summarize the DCU's new history. In the post-Crisis history, during the "Crisis" many heroes fought the Anti-Monitor's army. He attempted to collapse the positive universe's past and future into a single point in time to destroy it, leaving only the antimatter universe. Many of DC's characters had their histories rebooted. Wonder Woman's comic was relaunched entirely by Pérez, Wein, and Greg Potter. Superman was first re-envisioned in the limited series The Man of Steel by John Byrne; his comic was retitled The Adventures of Superman to make way for a new Superman series. Batman was minimally affected by the reboot, and his comic was not relaunched. However, he was still given an updated origin, courtesy of Frank Miller. In addition, Wally West replaced Barry Allen as the Flash, the Justice League's roster was changed, and characters DC acquired from other companies, such as Fawcett Publications and Charlton Comics, were integrated into the DCU. The practice of re-envisioning characters in the new DCU lasted well into 1989, with properties such as Green Lantern, Hawkman, Black Orchid, and the
