The Guyver is a 1991 American tokusatsu superhero film made in conjunction with Shochiku Films, loosely based on the Japanese manga series of the same name by Yoshiki Takaya.
The film tells of a young man, Sean Barker, who discovers an alien artifact called "The Unit" which changes Barker into an alien-hybrid super soldier called "The Guyver". Barker learns that a major corporation called "Chronos" is after the Guyver unit and soon discovers that the people behind Chronos are not human after all.
