In the course of the fictional story presented in the DC Comics event Infinite Crisis, several events in the fictional DC Universe's past were retroactively altered by either Superboy-Prime or the separation and re-merging of alternate Earths. Where not otherwise stated, this article deals only with changes known by the end of Infinite Crisis #7.
Superboy-Prime's changes
Superboy-Prime's attempts to punch his way out of the extradimensional space in which he had been trapped since the Crisis on Infinite Earths mini-series, along with Kal-L, Lois Lane, and Alexander Luthor, Jr., triggered "ripples" in the fabric of reality, causing events in the present to become undone and replaced by different versions of events. These changes were different for each person affected. Changes include:
Elasti-Girl and Negative Man of the Doom Patrol restored to life, the Chief restored to his original body and the team's history rebooted. The team eventually remembered its original history.
The infinite Earths, which had collapsed into a single world during Crisis on Infinite Earths, diverged again into multiple Earths during Infinite Crisis only to collapse back into a single "New Earth" with a slightly altered history. Examples of the revised history include:
Some retcons introduced during the Infinite Crisis storyline were the result of editors or writers deciding to revise certain story elements in order to fit a particular story or scenario. Examples include:
Maxwell Lord was always a villain conspiring against metahumans.
Subsequent continuity changes attributed to ''Infinite Crisis''
Some continuity changes were attributed to Infinite Crisis after it ended, without specifying whether Superboy-Prime or the collapse of the Multiverse caused them. These include:
Elasti-Girl's resurrection, attributed to Niles Caulder's experimentation.
Superman's membership in the Legion of Super-Heroes as a teenager, prior to the start of his public superhero career; Legion continuity prior to Crisis on Infinite Earths is substantially restored. However, the "Reboot" and "Threeboot" versions of the Legion remain.
Queen Hippolyta's Post-Crisis history as the Golden Age Wonder Woman of the 1940s is no longer valid.
