Mighty Brothers XX (マイティブラザーズXX Maiti Burazāsu Daburu Ekusu) is a co-op 3D action-platformer video game. Unlike the other Gashats made by Genm Corp, this game and its conceptualization and ideas were created by Emu Hojo. It also served as the basis for the Mighty Brothers XX Gashat. It is seemingly a part of the same series of games as Mighty Action X, although Kuroto Dan does not acknowledge it, labeling it as a "bootleg."
