キン肉マン 大暴れ!正義超人

After defeating the Demon Supermen, Kinnikuman and the others return to Planet Kinniku to hold a victory celebration. However, at this moment, a mysterious woman appears and attempts to assassinate Kinnikuman. This woman is the princess of the Hormone Tribe, the enemies of the Kinniku Tribe: Bibinba. She makes multiple attempts to kill Kinnikuman, but he remains unfazed, which causes her to develop feelings for him. However, due to the long-standing feud between their tribes, both Kinnikuman and Bibinba are taken away by their respective families. After both sides return to Earth, the prince of the Barbecue Tribe, Shishikababu, visits Bibinba's home once again to propose to her, declaring that he will defeat Kinnikuman. Bibinba, however, is somewhat unwilling. At that moment, a flying saucer appears in the sky, and a figure emerges from it—none other than the Dark Emperor of the Cosmic Kingdom. The Dark Emperor offers to help them defeat Kinnikuman, but his true intention is to invade Earth while the Justice Supermen are scattered across the globe...
