Seiji Sakaguchi
The manga was originally created for the "Bokura Magazine" in 1968 by Ikki Kajiwara and Naoki Tsuji. The manga would be reprinted by Kodansha comics, and made available in Hong Kong. Further versions include Sankei Comics and the Kodansha KC Special. The anime would be televised nationally in Japan, while two movies would be constructed from reusing footage of the series. Most of the environment and characters were fictional, but real-life pro wrestlers like Antonio Inoki, Giant Baba, Michiaki Yoshimura, Kintaro Ohki and Seiji Sakaguchi were included in the manga and anime as well.
