The Duke of Darkness was Paddy/Danny Sullivan, a police officer from an unnamed American city. When he was killed in the line of duty, Paddy discovered that he continued to exist as an "Earth-bound spirit." He decided to continue fighting crime as the Duke of Darkness.

The Duke of Darkness battles villains such as Professor Evil and Mr. Slumber, who attack people through their dreams. A police captain whom Paddy once served under viewed the Duke of Darkness as a very mundane nutcase and kept trying to lock him up. Although Paddy could escape at any time, he humored his former boss in between solving crimes.

His powers include intangibility, flight, super strength, and the ability to perceive & battle ghosts and demons. Even though he's a "ghost," he is able to be knocked out by a bump on the head such as in his first adventure.
