When Hippolyta and the other Amazons were trapped in a demonic dimension, she started receiving visions about the death of Wonder Woman. Fearing her daughter's death, Hippolyta created a false claim that Diana was not worthy of continuing her role as Wonder Woman, and arranged for a contest to determine who would be the new Wonder Woman, thus protecting Diana from her supposed fate. The participants of the final round were Diana and Artemis, and with the help of some mystic manipulation by Hippolyta, Artemis won the contest. Thus, Diana was forced to hand over her title and costume to Artemis, who became the new Wonder Woman and Diana started fighting crime in an alternate costume. Artemis later died in battle with the White Magician – thus, Hippolyta's vision of a dying Wonder Woman did come true, albeit not of Diana as Wonder Woman. Diana once again became Wonder Woman, a request made by Artemis in her last seconds. Artemis would later return as Requiem. Prior to Artemis' death, Hippolyta would admit to her daughter about her own part in Artemis' death, which strained their relationship as Diana was unable to forgive her mother for sending another Amazon to her death knowingly for the sake of saving her own daughter.
Her outfit did not receive any prominent change until after the 2005–2006 Infinite Crisis storyline. Similar to her chestplate, her glowing belt was also shaped into a "W". This outfit continued until issue #600 – J. Michael Straczynski's run of Wonder Woman's altered timeline changed her outfit drastically. Her outfit was redesigned by Jim Lee and included a redesigned emblem, a golden and red top, black pants, and a later discontinued blue-black jacket.
The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
As Themyscira's emissary to Man's World, Diana has made it her duty to lead by example, even if the differences between her birthplace and new home sometimes present hurdles for her to jump.

Cheetah sought revenge upon Veronica Cale for abandoning her, and attempted to murder her, but was stopped by Wonder Woman. Cale refused to transform Cheetah back to her human form, and Cheetah herself decided that she no longer desired to be human. Having left her Lasso of Truth binding Phobos and Deimos, Diana was given it back by the Olympian Gods and reunited with Steve.
Due to the reboot of the character following Crisis on Infinite Earths, numerous things no longer made sense in terms of continuity as it related to the remainder of the DC Universe. As her first overall appearance was now in continuity around the Legends miniseries, it no longer made sense that she was a founding member of the Justice League of America. This founding position was instead given retroactively to Black Canary. Later it was decided that she should be given this position back and thus both she and Black Canary were considered founding members of the Justice League. In reference to the Justice League though, although she has more than 400 combined appearances therein, she has had most of her character development in her own series.
In present-day Paris, Diana receives a photographic plate from Wayne Enterprises of herself and four men taken during World War I, prompting her to recall her past. The daughter of Queen Hippolyta, Diana is raised on the hidden island of Themyscira, home to the Amazonian women warriors created by Zeus to protect mankind. Hippolyta explains the Amazonian history to Diana, including how Ares became jealous of humanity and orchestrated its destruction. When the other gods attempted to stop him, Ares killed all but Zeus, who used the last of his power to wound Ares and force his retreat. Before dying, Zeus left the Amazons the island and a weapon, the "Godkiller", to prepare them for Ares's return.
One of the events that led to Infinite Crisis was of Wonder Woman killing the villain Maxwell Lord in Wonder Woman (vol. 2) #219. Maxwell Lord was mind-controlling Superman, who as a result was near to killing Batman. Wonder Woman tried to stop Superman, Lord (who was unable to mind control her) made Superman see her as his enemy Doomsday trying to kill Lois Lane. Superman then attacked Wonder Woman, and a vicious battle ensued. Buying herself time by slicing Superman's throat with her tiara, Wonder Woman caught Lord in her Lasso of Truth and demanded to know how to stop his control over Superman. As the lasso forced the wearer to speak only the truth, Lord told her that the only way to stop him was to kill him. Left with no choice, Wonder Woman snapped Lord's neck and ended his control over Superman. Unknown to her, the entire scene was broadcast live around every channel in the world by Brother Eye. The viewers were not aware of the entire situation, and saw only Wonder Woman murdering a Justice League associate. Wonder Woman's actions put her at odds with Batman and Superman, as they saw Wonder Woman as a cold-blooded killer, despite the fact that she saved their lives.
Both of those tales are worth reading, but the real highlight of this book is Wonder Woman #170, a story titled "She's a Wonder!" This standalone issue features an interview between Diana and Lois Lane as the two spend a day together and Lois learns a little about what it means to truly be Wonder Woman. This issue is widely regarded as one of the one of the best in Wonder Woman's long history, and it's well worth tracking it down even if you forego the rest of the book.
Not long after this, Athena sensed a dark destiny for the gods amidst the cosmic mechanations of Alexander Luthor Jr.. In the crisis created by his chaos, Diana was forced to kill Maxwell Lord, and incurred the ire of the world's public. The U.S. government responded by mobilizing against Themyscira, and Diana realized that as long as she was a target, the Amazons would never be safe. Diana prayed to the gods to take the Amazons to safety, but got more than she bargained for. On Olympus, she pleaded against Athena's decision to remove the gods from Earth's affairs. Regardless, the gods departed, leaving Diana bereft of family and faith.
