Dragon Ball: Revenge of King Piccolo (known in Japan as Dragon Ball: Tenkaichi Daibouken, the sub-title loosely translated to "The World's Greatest Adventure") is a 3D sci-fi fantasy action-adventure/fighting game developed by Media.Vision and published by Namco Bandai for the Wii in Japan (on July 23, 2009), North America (on October 20, 2009), and Europe (on October 30, 2009).
Based on the Dragon Ball manga and anime series, Revenge of King Piccolo follows kid martial artist Goku during his second foray in searching for the seven Dragon Balls (while encountering the nefarious Red Ribbon Army). After the main quest, the game skips ahead three years to the 22nd World Martial Arts Tournament, where a new foe (the Demon King Piccolo) makes his attack. Despite the overseas game name, the game does not mention Piccolo until the game's final stages.
Along with a single-player adventure mode, the game includes a versus fighting game mode (known as World Tournament Mode) for up to two players.
In World Tournament Mode, players can choose from 17 playable characters (11 of which must be unlocked beforehand).
