The four part "Sacrifice" storyline, one of the lead-ins to Infinite Crisis, ended with Diana breaking the longstanding do-not-kill code of DC superheroes. Superman, his mind controlled by Maxwell Lord, brutally beats Batman and engages in a vicious fight with Wonder Woman, thinking she is his enemy Doomsday.
In the midst of her battle with Superman, Diana realizes that even if she defeats him, he would still remain under Max Lord's absolute mental control. She creates a diversion lasting long enough for her to race back to Max Lord's location and demand that he tell her how to free Superman from his control. Bound by her lasso of truth, Max replies, "Kill me." Wonder Woman then snaps his neck.
Upon his recovery, Batman rejects Diana's attempt to explain her actions; Superman is no better able to understand her motivations. At a crucial time, a profound rift opens up between the three central heroes of the DC universe. In the final pages of The OMAC Project, the Brother Eye satellite – the deranged Artificial intelligence controlling the OMACs (Omni Mind And Community) – broadcasts the footage of Wonder Woman dispatching Maxwell Lord to media outlets all over the world, accompanied by the text "Murder."
At the start of Infinite Crisis, Batman and Superman distrust Diana: the latter can only see her as a coldblooded murderer, the former sees in her an expression of the mentality that led several members of the League to the decision to mindwipe their villains. When Batman tried to stop the League from mindwiping Dr. Light after the villain brutally raped Sue Dibny, Batman's memory was also altered. In Infinite Crisis #2 Brother Eye initiates the final protocol "Truth and Justice", which aims at the total elimination of the Amazons. A full-scale invasion of Themyscira is set into motion utilizing every remaining OMAC. Diana and her countrywomen, now isolated and alienated from the outside world, must fight for their lives.
In Infinite Crisis #3, the Amazons prepare to destroy the OMACs with a powerful new weapon, the Purple Death Ray, a corruption of the healing Purple Ray. Realizing that the battle is being broadcast to TV stations around the world, and edited to make the Amazons look like cold-blooded killers, Wonder Woman convinces the Amazons to shut the weapon down. She then assembles the Amazons on the beach of Themyscira to decide their next move.
Diana calls upon Athena, who transports Paradise Island and the Amazons to another dimension. Wonder Woman chooses not to join them, and is left to face the OMACs on her own. In Infinite Crisis #5, as Diana is breaking up a riot in Boston, she is interrupted by a woman she initially believes is Queen Hippolyta. However, the intruder identifies herself as the Wonder Woman of Earth-Two, Diana Prince, who has voluntarily left Mount Olympus to provide Diana with vital information and guidance. She advises her Post-Crisis counterpart to be "the one thing you haven't been for a very long time... human," and urges Diana to intervene in a fight taking place at that moment between the Modern Age Superman and his counterpart, Kal-L. Having left Mount Olympus, and with her gods' blessings gone, Diana Prince then faded away.
Wonder Woman manages to stop the Supermen from fighting, enabling them to work together in defeating the forces deployed by Alexander Luthor, Jr. and Superboy-Prime who are revealed as the true culprits behind the Crisis. In the Battle of Metropolis, Diana redeems herself by convincing an anguished Batman not to shoot Luthor, Jr. to death. At the story's conclusion, Diana, Bruce Wayne, and Clark Kent interact like the friends they were in the past, and Diana declares her intention to do some soul-searching before returning to her role as Wonder Woman.
Near the conclusion of the Infinite Crisis the history of Earth is modified. Wonder Woman's Silver Age past is restored, and it is revealed that she has also served as a founding member of the Justice League. This notion was evidenced in the merging of the Earth-One Wonder Woman and the 1987 rebooted Wonder Woman by Alexander Luthor.
Wonder Woman vol. 2 was one of several titles canceled at the conclusion of the Infinite Crisis crossover, #226 (April 2006) being the final issue. The title included 228 published issues, including an issue #0 between #90 and #91, and issue #1000000 between #138 and #139.
