As Wonder Woman joins the Battle against Doomsday, she arrives just in time to save Batman from Doomsday's lethal thermal blast, deflecting the beams with her indestructible bracelets. She then jointly attacks Doomsday with Superman while Batman tries to expose the creature to Kryptonite, allowing its destruction. She relentlessly battles the monster, and despite Doomsday being stronger, Wonder Woman held her own, parrying a tremendous punch with the Sword of Athena, and then slicing off Doomsday's right arm with it. Eventually, Batman baits the monster into coming closer to her, allowing Wonder Woman to hurl the noose of her unbreakable Lasso of Hestia around his torso.
While Diana stood admiring the replica, Bruce Wayne appeared. He proceeds to angrily confront her by grabbing Diana's arm and asking her about the information device that she had stolen. Bruce claims to see right through her "babe in the woods" act, saying that while Diana doesn't know him, he's met "a few women like [her]". Diana, however, calmly smiles and retorts that Bruce has never met any women like her. She then proceeds to tell Bruce that she was unable to obtain anything from Bruce's device, due to Lex Luthor's data having military-grade encryption. Diana explains her intention to re-obtain her photograph from Luthor, stating that she only borrowed Bruce's device, and has already returned it to him shortly beforehand (placing it into the glove compartment of his car), before calmly excusing herself and leaving.
Another major outfit change for Wonder Woman came about as part of DC Comics' 2011 relaunch of its entire line of publications, The New 52. The character's original one-piece outfit was restored, although the color combination of red and blue was changed to dark red and blue-black. Her chest-plate, belt and tiara were also changed from gold to a platinum or sterling silver color. Along with her sword, she now also utilizes a shield. She wears many accessories such as arm and neck jewelry styled as the "WW" motif. Her outfit is no longer made of fabric, as it now resembles a type of light, flexible body armor. Her boots are now a very dark blue rather than red. The design previously included black trousers, but they were removed and the one-piece look was restored during the time of publication.
In modern times, Diana operates as the curator of the Louvre Museum as Diana Prince. Two years following the Battle of Metropolis, Diana came into conflict with Lex Luthor, who discovered a photograph of Diana and the Wonder Men during his search for metahumans. During her pursuit of Luthor, Diana crossed paths with Bruce Wayne, who discovered her secret after their confrontation during his search for the White Portuguese. Later, along with the photograph on Luthor's files Bruce sent her, Diana discovered the evidence of metahumans in the world. With her mission fulfilled, Diana prepared to depart back to London, but the emergence of the monstrous Doomsday led Diana to ally herself with Superman and Batman to take down the monster in a fierce battle that ended with the tragic death of Superman.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
