The 'Budokai Tenkaichi' title of the North American version is a rearranged version of Tenkaichi Budokai (天下一武道会, Tenka'ichi Budōkai roughly 'Strongest Under the Heavens Martial Arts Tournament'). However, the opening theme to the game is the TV series' second opening, ' WE GOTTA POWER' (featured in the Japanese version the English version includes a different, non-vocal song), which is also performed by Kageyama. The 'Sparking!' in the Japanese title references the last lyric found in the chorus of the first opening theme to the Dragon Ball Z anime series, ' Cha-La Head-Cha-La,' performed by Hironobu Kageyama. After three games released on PS2, the series mechanics continued in the 2009's Dragon Ball: Raging Blast, the 2010's Dragon Ball: Raging Blast 2 and the 2011's Dragon Ball Z: Ultimate Tenkaichi for PS3, as well as the 2010's Dragon Ball Z: Tenkaichi Tag Team for PSP.
Each installment was developed by Spike, while they were published by Namco Bandai in Japan and Atari in all other countries. The Dragon Ball Z: Budokai Tenkaichi series, originally published as Dragon Ball Z: Sparking! (ドラゴンボールZ Sparking!, Doragon Bōru Zetto Supākingu!) in Japan, is a series of fighting games based on the anime and manga Dragon Ball by Akira Toriyama.
