President Luthor has publically laid the blame for the meteor on Superman, and offered a massive bounty to anyone who brings him in. As Superman and Batman fly to Washington to confront Luthor, villains crawl out of the woodwork, each looking to bring Superman down for the reward money. But the villains aren't the only ones lining up to bring Superman in.
