Fist of the North Star

is a 1986 Japanese adult animated post-apocalyptic martial arts film based on the manga of the same name. It was produced by Toei Animation, the same studio who worked on the TV series that was airing at the time, with the same cast and crew working on both projects. Unlike the TV series, the film is not a direct adaptation of the manga, but instead tells an alternate story that rearranges characters and plot elements from the manga's first 72 chapters. However, the film retains the more violent content of the original manga, which the television series lacked. Plot A global nuclear war has turned most of Earth into a contaminated wasteland, with humanity's survivors now fighting over the few uncontaminated food and water supplies still remaining. Kenshiro, a master of the deadly martial art Hokuto Shinken, is traveling with his fiancee Yuria when they are confronted by a gang led by Ken's former friend Shin, a master of the rival Nanto Seiken style. Shin proclaims that he has been in love with Yuria for a long time and challenges Ken over her, with no law interrupting in the matter. After defeating Ken in combat, Shin engraves seven wounds on Ken's chest and leaves him for dead, taking Yuria with him. Ken's eldest brother-in-training Raoh, having witnessed the fight without intervening, returns to his dojo, where he finds his sensei Ryuken meditating. Raoh challenges Ryuken's decision to choose Ken as the Hokuto Shinken successor over him and kills him, proclaiming he will become the ruler of the new world. A year passes and Ken now wanders the wasteland as a hero who protects the weak and innocent from those who prey on them. He rescues a couple of young children named Bat and Lin from a gang of bandits and allies himself with another Nanto Seiken master named Rei, who is searching for his kidnapped sister Airi.
