The Octopus (Zitzbath Zark) is a supervillain from the comic book The Spirit by cartoonist Will Eisner. He first appeared in The Spirit on July 14, 1946, and became the primary nemesis in later stories. The Octopus has never showed his face in the stories, but readers could always identify the character by the distinctive gloves he always wore. A master of disguise, The Octopus was involved in the epic fight with The Spirit, which left Denny Colt temporarily blind.
The film combines elements of Dr. Cobra from The Spirit comics with the Octopus in that he is revealed to have been responsible for the Spirit's resurrection and immortality thanks to a regenerative formula he invented and injected himself with as well after succeeding. His quest in the film is to get his hands on the Blood of Heracles to drink and become a god. Following a fight with the Spirit, the Octopus escapes but ends up with Jason's Golden Fleece desired by Sand Saref, now with the blood. After going to desperate measures trying to find Sand and kill the Spirit, the Octopus hires a beautiful assassin, Plaster of Paris, to take down his nemesis. At the end of the film, the Octopus is finally defeated in a manner similar to his demise in the comic, being blown up by a grenade. However, his severed finger is found by Silken Floss, leading to the possibility that the real battle has only just begun.
