The King of Crime in Simpsons Comics & Stories.
The King of Crime is a fictional character, a villain and mafia kingpin in the Radioactive Man universe.
The King has a proclivity for armed robbery. In Radioactive Man #58, Radioactive Man actually starts committing crimes of his own and outdoes the King, robbing from the First Bank of Zenith, the Zenith Museum, and a government shipment of gold. The King of Crime challenges him to a duel for control of the underworld, but Radioactive Man defeats him and reveals that he only committed the crimes as a ruse to get the King out in the open. All gets returned to its rightful owners and the King goes to jail.[1]
The King later got out of prison and reestablished himself in a penthouse apartment, taking back his place as the King of Crime. Radioactive Man confronts him there in Radioactive Man #418.[2]
