Riki-Oh

Riki-Oh (Japanese: 力王, Hepburn: Riki-Ō) is a Japanese manga series written by Masahiko Takajo and illustrated by Tetsuya Saruwatari. It was serialized in Shueisha's seinen manga magazine Business Jump from 1987 to 1990, with its chapters collected in 12 tankōbon volumes. The story follows the titular Riki-Oh, a young man who has learned the martial art of Naike Kenpō from one of Chiang Kai-shek's bodyguards, and has become so strong that he can punch holes through people and solid objects.

A two-episode original video animation (OVA) was released in 1989 and 1990, and a live-action film, Riki-Oh: The Story of Ricky, premiered in 1991.
