Shortly after the team assembled, Wonder Woman assisted in helping a newly resurrected Superman regain his memories. With the team now fully assembled, Wonder Woman contributed to the successful offensive against Steppenwolf, forcing the alien invasion into retreat.

Issue #600 introduced Wonder Woman to an alternate timeline created by the Gods in which Themyscira had been destroyed and the Amazons scattered around the world. In this timeline, Diana is an orphan raised in New York who is learning to cope with her powers. The entire world has forgotten Wonder Woman's existence and the main story of this run was of Diana trying to restore reality even though she does not properly remember it herself. Diana has no memories of her prior adventures as Wonder Woman, recollecting her memories in bits and pieces and receiving different abilities and resources (such as the power of flight and her lasso) during the progression of her adventure. A trio of Death Goddesses called The Morrigan acted as Wonder Woman's main enemies. Diana ultimately defeats the evil goddesses and returns everything back to normal.
The "Year One" storyline retells Diana's origin growing up on Themyscira. She lives an idyllic life and harbors interest for the outside world, and the first connection to it comes in the form of Steve Trevor, who crashes on the island and is the sole survivor. A contest is held to determine which Amazon is the best candidate to take Steve home, with Diana volunteering despite knowing the cost to leave the island is to never return. Diana wins the contest and departs with Steve. Once arriving in America, Diana is taken into custody by the government to discern her origins. She meets Etta Candy and Barbara Ann Minerva along the way. While incarcerated Diana is visited by the gods in animal form and bestow upon her powers of strength, speed, agility, durability, and flight. She discovers Ares, the god of war, is working to destroy humanity. Accepting her new role in Man's World, Diana, with the help of the gods in animal form, subdues Ares with the lasso. Now called Wonder Woman, Diana becomes one of the world's greatest heroes.
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.
