Bio-Senshi Dan: Increaser to no Tatakai (ダン バイオ戦士DAN インクリーザーとの闘い) is a 1987 action-adventure game that was released exclusive in Japan for the Family Computer. An attempt to bring this game to North America under the title Bashi Bazook: Morphoid Masher was sought. Eventually, the idea fell through due to its similarity to Xexyz and the game remained in Japan. However, the game was completed, and ROMs of the game are widely circulated on the Internet.
