After Crisis on Infinite Earths, George Pérez rebooted the character in 1987. She wore an outfit similar to her 1970s one, but now with a larger glowing golden belt. This outfit continued until William Messner-Loebs' run, which had Diana pass on the role of Wonder Woman to Artemis. No longer Wonder Woman, Diana sported a new black biker-girl outfit designed by artist Mike Deodato Jr. After John Byrne took over writing and art duties, he redesigned the Wonder Woman outfit (Diana was reinstated as Wonder Woman at the end of Loebs' run) and joined the emblem and belt together.
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.
Hermes attacked Wonder Woman there, refusing to simply give up the child, but during their battle, War ripped the baby from Demeter's womb and disappeared. Unable to let a grave wound such as that go unattended, Diana saw to Demeter first, and the goddess warned that War could not be trusted. Worriedly, Diana and Orion returned to Manhattan to find that War had returned the baby to Zola. At last, the baby and his mother were reunited - and Orion would not have to look any further for the child he needed to kill.
