Writer Gerry Conway brought Steve Trevor back to life again in issue #271 (September 1980). Following Diana's renunciation of her role as Wonder Woman, a version of Steve Trevor from an undisclosed portion of the Multiverse accidentally made the transition to Earth-One. With Diana's memory erased by the Mists of Nepenthe, the new Steve again crash-landed and arrived at Paradise Island. After reclaiming the title of Wonder Woman, Diana returned to Military Intelligence, working with Trevor and re-joined by supporting characters Etta Candy and General Darnell.
A shocked Diana apologized to Antiope and abruptly left the training session. She wandered off to a cliff on the Themysciran seashore and examined her gauntlets in awe. As she stood there, she noticed an airplane burst through the forcefield surrounding Themyscira and crash in the nearby waters. Seeing even from a great distance away that someone was trapped inside the sinking aircraft, she leaped down the ocean and rescued the pilot, none other than a human soldier named Steve Trevor. She pulled him out of the water and onto the Themysciran shore. As he came to, she noted in disbelief that he was a man, as she had never seen one before. Though somewhat confused, Steve affirmed that he was, rhetorically asking whether or not he looked like one.
In August 2010 (issue #600), J. Michael Straczynski took over the series' writing duties and introduced Wonder Woman to an alternate timeline created by the Gods in which Paradise Island had been destroyed and the Amazons scattered around the world. In this timeline, Diana is an orphan raised in New York. 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. A trio of Death Goddesses called The Morrigan acted as the main enemy of Wonder Woman. In this run, Wonder Woman wears a new costume designed by Jim Lee. Straczynski determined the plot and continued writing duties until Wonder Woman #605; writer Phil Hester then continued his run, which ultimately concluded in Wonder Woman #614.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
