Leopardon is the giant robot featured in the Japanese tokusatsu series 'Supaidāman' (Spider-Man), produced by Toei Company in the late 1970s. Piloted by Takuya Yamashiro, the Japanese Spider-Man, Leopardon serves as his powerful mechanical ally in battles against the evil Iron Cross Army. The robot is notable for its iconic transformation and finishing move, the Sword Vigor. Leopardon played a key role in the series, often turning the tide in Spider-Man's favor during climactic confrontations.
