Seigi Choujin vs. Ancient Choujin
This film is the first to feature anime original character Kinkotsu-Obaba. Although this film is set after the Golden Mask Arc, the character Geronimo does not appear as an active fighter until the next film. He does, however, appear in flashbacks to the Golden Mask conclusion. This is also the second time voice actor Ichirō Nagai appears in a Kinnikuman work playing the main villain. He had previously appeared in the TV Special. It also features the return of voice actors Kōzō Shioya and Yasuo Tanaka, who had previously appeared in the first film  Stolen Championship Belt. Synopsis. While Kinnikuman is on vacation with Mari-san's kindergarten class at Easter Island, the young Kouichi-kun, who uses a wheelchair, laments being with Kinnikuman, preferring to instead be with his favorite Seigi Choujin Buffaloman. Meanwhile, the other Seigi Choujins are also vacationing at ancient landmarks
