Season 1
Onigawara, the director of the International Secret Police Agency, looked forward to making Takeshi a top-notch criminal investigator. Takeshi was given training, which turned him into an all-around sportsman as well as martial arts expert. However, Takeshi's attitude toward crime-fighting was so incompatible with Onigawara's, that he disowned him. For a while Takeshi investigated crime alone; then he became a private detective Joe Kuruma's assistant and general handyman. Secretly, however, Takeshi obtained from a scientist a new artificial polymer, polymet, that was far stronger than steel. With this polymet Takeshi transformed himself into Hurricane Polymar, an invincible costumed hero for fight for the justice and defeat to the different gangs.
