Release Date - December 27, 1994
Plot Overview
Kidou Butouden G Gundam is based on the 1994 anime TV series of the same name. The first Gundam production not set in the continuity established in the 1979 original series of the franchise, G Gundam presents a world in which global conflicts are settled in a yearly tournament fought between Gundam mecha, each representing its nation's qualities (and stereotypes). Naturally, this premise was adapted into a one-on-one fighting game.
Character Overview
Kyoji is Domon’ s twisted brother. Kyoji convinces his father to build the Devil Gundam, a horrific monstrocity. Here, he’s the last boss of the game. Pretty typical as far as final bosses go too. Cheap, overly powerful, extremely good defense, but still no match for the supremely broken Rose Gundam.

Graphics and animation
Tiles, sprites, and palette have been changed/improved in many places. Animation of backgrounds has also been added in many places instead of static backgrounds from the Japanese version. Fonts and other symbols have been redrawn on the title screen and cutscenes. New blocks (structures consisting of several tiles for levels) have been added, which adds new details to the levels, unusual structures, and a new approach to level design.
