Nabbed this from a website: The Guyver Unit before exposed to a host looks like small module. When in this state, it is referred to as "Guyver Unit" After the Guyver organism is released; there is a transformation between the host and the organism. The organism attaches itself to the host's brain with little fibers and alters the host DNA. Within the first couple of minutes, the transformation is complete. The key to the Guyver is its control metal. The control metal serves as a power regulator that controls the Guyver's power out put. The Guyver increases the host's own strength by 10,000 fold. The control metal is the Guyvers key, remove the key and destroy the Guyver. Without the control metal there to regulate the power, the organism will start to eat the host alive. However, the control metal, if not damaged, will generate another Guyver! The new Guyver will be controlled by the organism, which can not tell friend from foe. The host will be completely restored, but will be in a coma type state for 24 to 48 hours or until someone that knows the host can wake the host up.
