Maximillian "Maxie" Zeus was a former shipping CEO turned supervillain.
Maximilian Zeus was the CEO of Maximilian Shipping Company in Gotham City. When his business started to struggle, he used his company to smuggle for the Mafia. A combined result of the stress as well as the luck that he escaped notice from the authorities caused Maximillian to believe he was not bound by the laws of earthly governments. He had always admired Greece and its history, even traveling there with his assistant/girlfriend Clio. After his mental breakdown, he believed himself to be the supreme Greek God Zeus and presented himself as such, dressing in a period costume and carrying a metal thunderbolt that could emit an electrical charge. His penthouse, which occupied the entire top floor of his office building, was decorated in the Greek style and stretched above Gotham as his Mount Olympus.
Dubbing himself Zeus, he planned to steal the federal government's Electrical Discharge Cannon, attempting to claim Gotham as his private domain. Zeus was so deluded that not even Clio could completely convince him to stop.
After stealing the cannon, Zeus first met Batman, who he referred to as Hades. Batman later infiltrated Zeus' complex and tried to overload the cannon with Zeus' thunderbolt rod. Zeus leapt after it and electrocuted himself unconscious. He was later sent to Arkham Asylum, where he viewed the place as the real Mount Olympus, associating the inmates with Ancient Gods. He then proclaimed that he was home at last.
