Within the story, he appeared on the scene and eventually came to rival Superman, possessing the same powers as he, but not his weaknesses. His popularity surpassed Superman which left him depressed, feeling like a has-been. It was later revealed that Wonder Man used to be Ajax, one of Superman's duplicate robots that he used for help or hiding his identity. Ajax was kidnapped by the Superman Revenge Squad while in space, who turned him into a real living being while still having his bionic super-powers. The invaders wanted to use him to remove Superman so that he would no longer be in their way for their attack. Wonder Man, not being evil, thwarted their plan with Superman when he learned of their full intentions. After the aliens' defeat, Superman offered Wonder Man the chance to fight at his side, but the aliens installed a death-mechanism in him that was triggered to kill him within a week. Wonder Man died, and then laid in a grave which said that he was born a robot, but died a human.
Hercules
Hercules appears during the events of One Year Later. Now shaven and bearing an updated version of the armour worn in the Hercules Unbound series, he replaces Wonder Woman as an agent of Olympus. He is referred to as "Wonder Man" by Cheetah and Nemesis. He temporarily set up his base in the Greek Embassy. In Wonder Woman v3 #4, Hercules is revealed to have lied about his reasons for returning to Earth and was actually partnering with Circe.
Dane of Elysium
Dane of Elysium was introduced in Countdown Presents: The Search for Ray Palmer - Superwoman/Batwoman #1 as an inhabitant of Earth-11, which is home to reverse-gendered superheroes. He is the reverse gender of New Earth's Diana Prince. It is revealed that Dane was exiled from "Woman's World" when he killed Maxine Lord on nationaltelevision for controlling Superwoman. He eventually led his male Amazons into battle against the United States, but was defeated by Superwoman and the Justice League. Following the Flashpoint reboot, Earth 11's gender-reversed Wonder Woman is Wonderous Man, as shown in The Multiversity Guidebook. Wonder Man from Earth-11 is separate from Wonder Warrior, who was another male version of Wonder Woman created by Mister Mxyzptlk and existed in a pre-Crisis reverse-gendered reality.
