Guyver 0 was the first human that was ever merged with a bio-booster armor.
The first Guyver, dubbed Guyver 0, was the first human that was ever merged with a Bio-Booster armor. Shortly after the creators had refined the Zoanoid process on humans they became curious to see what would happen if they used a unit on a normal person. Testing it on a random Cro-magnon man they witness the awesome power that a bio-boosted human possessed. However when they ordered the human to retract the armor they quickly learned what curiosity could get them.
While bio-boosted they learned a human was immune to their telepathic commands. 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.
