Bio-Booster Armor Guyver(1985)

Sho and his friend, Tetsuro, stumble upon a strange orb-like mechanism, the Guyver Unit, in the woods. It physically bonds with Sho and turns him into the alien soldier, Guyver. His mission is to protect the Guyver Unit from the Japanese corporation known as Chronos. They are after it and two other units just like it. To retrieve the object, they send out vicious monsters known as Zoanoids. So no one is safe in Sho's life; not even himself.



Note: In an interview for the Blu-ray release of the movie Guyver 2: Dark Hero (September 8, 2026), Takaya revealed that he won't be able to continue the manga. He suffered a cerebral infarction which paralyzed the right side of his body, along with damage to his brain that caused his concentration and judgment to decline, resulting in being forced to retire from his work as a mangaka.
