In the "Watchmen" sequel "Doomsday Clock," Doctor Poison attended the meeting established by the Riddler and mentioned a rumor that Wonder Woman was forcefully dragged back to Themyscira by her fellow Amazons. Wonder Woman comes out of hiding to address the United Nations, hoping to defuse the metahuman arms race. However, the summit is interrupted by Black Adam, the Creeper, and Giganta, who take advantage of the absence of most of Earth's superheroes to attack the UN at the time when the superheroes were confronting Doctor Manhattan on Mars.
The Crisis on Infinite Earths crossover of 1986 was designed and written with the purpose of streamlining most of DC's characters into one more-focused continuity and reinventing them for a new era, thus Wonder Woman and Steve Trevor were declared to come from the Earth-Two dimension, and along with all of their exploits, were erased from history, so that a new Wonder Woman character, story and timeline could take priority.
Comic books were more or less invented in 1933 by Maxwell Charles Gaines, a former elementary school principal who went on to found All-American Comics. Superman first bounded over tall buildings in 1938. Batman began lurking in the shadows in 1939. Kids read them by the piles. But at a time when war was ravaging Europe, comic books celebrated violence, even sexual violence. In 1940, the Chicago Daily News called comics a “national disgrace.” “Ten million copies of these sex-horror serials are sold every month,” wrote the newspaper’s literary editor, calling for parents and teachers to ban the comics, “unless we want a coming generation even more ferocious than the present one.”
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.
