they then meet him and are offered a deal. Neron appears to be unable to resist a chance to make a deal; he is attracted to deal-making to corrupt and gain souls. He is also attracted to purity and wishes to corrupt and destroy it wherever he finds it. Both of these attractions have led to his defeat many times. Underworld Unleashed Neron's first appearance to Earth's supervillains and superheroes occurs during the Underworld Unleashed crossover event, when he plots to take over Earth by fulfilling the greatest desires of dozens of supervillains and superheroes in exchange for their souls. When attempting to tempt Green Lantern V (Kyle Rayner), he offers to bring back from the dead Rayner's girlfriend, Alexandra deWitt; similarly he offers to bring Robin II (Jason Peter Todd) back from the dead for the Batman and to bring the Flash II (Bartholomew Henry "Barry" Allen) back from the dead for the Flash III (Wallace Rudolph "Wally" West II).
