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'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.
