Beast Gear World, known as Beast Machine World (獣 (じゅう) 機 (き) 界 (かい) Jūkikai) in Japanese, is a series of Beast-Warrior monsters used by Yosh Imimi in the Yu-Gi-Oh! SEVENS anime. Design-wise, its members are based on anthropomorphic animals in biker gear. It is based on the Hokuto no Ken (known as Fist of the North Star in English) franchise, with several cards alluding to its "Century's End" post-apocaliptic setting as well as its characters.
