Dragon Ball Z: Gekitō Tenkaichi Budōkai (ドラゴンボールZ 激闘天下一武道会), translated as "Dragon Ball Z: Fierce Battle at the 'Number One Under The Heavens' Martial Arts Tournament", is a video game developed by TOSE and published by Bandai for the Japanese Famicom on December 29th 1992. It is based on the Dragon Ball Z anime TV series and is also the first game to be released that requires (and came packed with) the Bandai-produced Datach Joint ROM System card-reader attachment.
This is the first fighting game to be based on the DBZ series. The game features many playable characters from the series (at least 28) and most of their transformations, with a corresponding trading card for each. There is also cards for varying versions of each single character, all with completely different attributes, statistics, and usable special moves. The game is unplayable without the Datach add-on and compatible cards to scan.
