Battle Formation was a strategy game for the PlayStation that used villains from the Ultraman, Gundam, and Kamen Rider franchises as playable characters. The player would use mobile suits, kaijin, and kaiju from various entries of each franchise to conquer an island until they encountered the final boss simply known as Keeper.
The layer takes the roe of one of nine commanders to command their army of villains with three from each franchise; however, these commanders are not playable themselves. The commanders from Gundam include M'Quve, Char Azneble, and Lady Une. The commanders from Kamen Rider include Dr. Shikigami, King Dark, and Shadow Moon. The commanders from Ultraman include Alien Mephilas, Alien Pitt, and Yapool.
