Dragon Ball: Curse of the Blood Rubies is a 1986 Japanese animated martial arts fantasy adventure film and the first alternate continuity in a series of feature films in the Dragon Ball anime franchise, based on the manga of the same name by Akira Toriyama. The film is a modified adaptation of the initial story arc of the manga, with the original character King Gurumes substituting Emperor Pilaf's role as the main antagonist. It depicts how Goku meets up with Bulma, as well as Oolong, Yamcha, Puar and finally Master Roshi during his first search for the Dragon Balls. Gurumes and the other new characters were designed for the film by Toriyama.
