Dead or Alive: Final is a 2002 Japanese cyberpunk science fiction film directed by Takashi Miike. It is the third in a three-part series, preceded by Dead or Alive in 1999 and Dead or Alive 2: Birds in 2000. The films are not connected in any apparent way except by director Takashi Miike and stars Riki Takeuchi and Show Aikawa. Besides Japanese, a lot of the conversation of the film is in Cantonese, and some is in English. Often two people will talk to each other using different languages.
Set in a post apocalyptic Yokohama where the population is kept under rigid control by a homosexual megalomaniac mayor. The citizens are administered drugs to suppress heterosexual urges. Officer Takeshi Honda (Riki Takeuchi) is a hard boiled cop enforcing the mayor's agenda, and Ryō (Show Aikawa) is a mellowed out drifter that hooks up with a gang of rebels. When the gang kidnap Takeshi's son, it begins a series of events leading to an inevitable showdown.
While walking to the final confrontation, flashbacks to the first two films in the trilogy are shown, connecting all three films in a non-literal way. At the film's climax, the two characters fuse into a giant robot with a penis shaped head
