and Legion of Super-Heroes battle Mongul, Superman finally defeats him as the Legion destroys the Sun-Eater. Mongul eventually attacks Superman on his birthday and ensnares him with a Black Mercy, an alien plant that feeds off a victim's "bio-aura" while rendering the victim incapable of fighting back, giving them a realistic vision of their own perfect "dream world" in return. Meanwhile, Mongul nearly killed Wonder Woman while mocking her views that women are equal. In the end, thanks to Batman, Robin and Wonder Woman, Mongul becomes the plant's next victim and dreams of himself as ruler of the universe. Modern Age (1985–present) After the 12-issue limited series Crisis on Infinite Earths, DC Comics retconned the histories of some major characters to update them for contemporary audiences. The original stories involving Mongul were no longer in continuity, and the character was reintroduced as the ruler of Warworld, a space empire where Mongul entertains the citizens with gladiatorial games. Mongul's ship captures a dying Superman, who was floating adrift in outer space after he exiled himself from Earth, and Mongul decides to use him in the games, but Superman joins forces with the alien warrior and Mongul's champion Draaga and makes Mongul flee. Mongul is then persuaded via torture to serve the Cyborg Superman to gain vengeance on Superman and to try to turn the Earth into another Warworld. In the process, Green Lantern Hal Jordan's home, Coast City, is destroyed, which leads to him joining Superman and his allies to defeat Mongul. After his defeat, Mongul is imprisoned in a prison for intergalactic criminals, only to break out during a riot. His first target is Green Lantern; he learns that the one whom he faces, Kyle Rayner, is not the one he fought earlier. Mongul is defeated when Kyle's ring shows no weakness to yellow. Mongul is re-imprisoned. Mongul breaks out of the lunar penal colony, killing everyone there, including prisoners who are left to die in the vacuum of space. His ship is almost wrecked and he is near death; he is teleported to a planet and saved. In return, he takes over the planet and ends up being left alone as the inhabitants prefer dying due to a virus than his tyranny, until he ends up finding two babies immune to the virus (a story started in Showcase '95 #7, with the two babies appearing in Showcase '95 #8;
