Hurricane Polymar

Takeshi Yoroi appears to be little more than the easygoing assistant of hopeless private detective Joe Kuruma. In truth, he possesses the Poly-Met, a special helmet that transforms him into the superhuman fighter Hurricane Polymar and lets him reshape his armored body into powerful combat forms.

While Joe chases cases with more confidence than competence, Takeshi secretly handles the dangers that ordinary detectives cannot. Criminal syndicates, bizarre villains, and monsters threaten the futuristic city of Washinkyo, and each new case forces him to protect the people around him without exposing the identity beneath the red armor.
