Kishin Dōji Zenki FX: Vajra Fight is a side-scrolling action-platform beat 'em up video game developed and published by Hudson Soft exclusively for the PC-FX in Japan on 22 December 1995. It is the fourth title to be based upon Kikuhide Tani and Yoshihiro Kuroiwa's Zenki shōnen manga and anime series, which is based on the Japanese folklore concerning the Great Bodhisattva Jinben Ozunu Enno, and it also has been compared with other titles in the same genre such as Taito's The Ninja Warriors and Treasure's Guardian Heroes. Following the second arc of the manga, which was later adapted into the anime, players assume the role of either Zenki or Chiaki Enno and fight against monsters across several locations in order to rescue a girl named Nozomi and protect Japan from the enemies.
