Kamen Rider is the masked heroic title used by the main cyborg protagonist in Shin Kamen Rider. In the film, he is a transformed human fighting against the SHOCKER organization and its monstrous agents. The character serves as the central hero, driven by a sense of justice, identity, and resistance against dehumanization. Rather than a traditional personal name, Kamen Rider is a mantle that represents the conflict between human will and artificial transformation.
