A spoof of the Batman comics, with the superhero Pith Possum and his sidekick Obediah the Wonder Raccoon fighting crime in Possum City when called by the gorilla Commissioner Stress and the monkey Lieutenant Tension. Pith Possum's true identity is lowly tabloid copyboy Peter Possum. Pith Possum fights various enemies with his recurring one being a mad lumberjack named Dr. Paul Bunion. Pith Possum also has developed a crush on a female human reporter named Doris Deer who mostly loves Pith Possum more than his true identity. It was stated in the first episode that Pith Possum was an ordinary lab opossum until he gained ultra opossum-like abilities upon an experiment gone wrong. The titles of the episodes are completely unrelated to their contents but rather over the top titles always using the word 'dark' or 'darkness' and often with the words 'black' and 'night' (e.g., The Phantom Mask of the Dark Black Darkness of Black, Return of the Night of Blacker Darkness, Return of the Dark Mask of Phantom Blackness, etc.). Jim Cummings provided the narration in most episodes.
