The first human to merge with the Guyver unit when the creators came to earth.
The first Guyver was an experiment conducted by the Creators aeons ago when they first came to earth. They were curious as to how their newly developed weapons would react to one of the Cro-magnon. However, the first Guyver (dubbed Guyver 0) attacked the Creators, destroying one of their ships. The human would not remove the armor when ordered to. As all humans were programmed to be telepathically controlled by the creators, this human would not listen. Because of this uncontrollable nature the bio-booster human was then called 'Guyver' a word meaning "out of control" in the Creators' language. They gave the 'Unit Remover' to Archanfel (the first Zoalord), who then proceeded to remove the Unit from the human and subsequently incinerate him.
A live action Americanized movie based on the Bio Booster Guyver manga.
