Johnny and attacks him to prepare him for future challenges. Johnny is beaten repeatedly, but he is finally able to disarm Zatch. Rallying the villagers, they travel to the coast, opposite from an island that houses the royal city and Colonel Chi's dungeon. Unable to go by boat due to an impassable reef, Johnny and Adam tell the Patusanis to make surfboards. They then paddle to the unguarded side of the island. Landing on the island, Johnny and Zatch lead the attack on the royal city, taking down Chi's henchmen and freeing Mac. During the battle, Zatch is revealed to be the boys' paternal uncle. Johnny confronts Colonel Chi, successfully defeating him by knocking him into a body of water with the help of Adam and his Game Gear. With Chi's rule undone, peace is restored to Patusan. Johnny is seated as the heralded warrior prince with Ro-May as his princess and Adam as a prince. Johnny declares the monarchy to be dissolved and announces that Patusan will operate as a democracy. His reason for doing this is for the people to finally be free of rule, good or evil. Cast Production and video game Surf Ninjas was filmed during the summer of 1992. Filming locations included Thailand and Hawaii. The second half of the film was shot first, and the crew moved to Los Angeles to film the first half. New Line Cinema and Sega of America established a financial relationship in which a Sega Game Gear video game (US and PAL versions) would be developed for the film. Game designers began developing the video game Surf Ninjas when the film was only in its scripting phase, receiving creative input from director Neal Israel. In conjunction with the Game Gear title, a Sega Genesis game was also planned. In turn, Sega partially financed the film. Screenwriter Dan Gordon said that he wrote action sequences that would both suit the film and serve as a springboard for the video game. In the film, one of the lead characters is shown playing the Surf Ninjas video game on a Sega Game Gear. The video game was released in August, before the film's release, and it was considered the first movie-based video game to precede the film itself. Surf Ninjas video games were also released for the Amiga 1200 computer and an unrelated CD32 console in 1994 by Flair Software/MicroValue. Release The
