Sho Fukamachi is the main protagonist of the series, Shō is seventeen years old and a second-year student at Narisawa high school. As he is the host for the first Unit activated, he is known as "Guyver I".
When he initially transformed into the Guyver, Sho was unconscious from the trauma of having the Unit forcibly bond itself to him. However, the Guyver itself was able to deal with the threat of the Zoanoids that had been disbatched to retrieve the lost Guyver Unit. Once Sho awakened from the fugue-like state that he had entered while bonding to the Unit, he was initially terrified of the armor that he found himself wearing, as well as its capacity for sheer destruction.
These feelings lead to him rejecting the armor, which in turn caused the armor itself to retreat from him and store itself in the sub-dimension that the armor resides in when not in use.
However, this was only a temporary reprive; the armor itself was still firmly bonded to him. Nothing short of the Unit Remover would be able to change that fact. Sho, however, was simply relieved to be free of the armor; he didn't know yet that he would not be able to get out of the situation so easily. When the next group of Chronos thugs confronted him - a pair of Ramotith lead by Guyver II in the 12 part OVA, and a group of Ramotith lead by a Vamore in the 2005 TV series and the manga - he was again able to call upon the Guyver to protect himself and his best friend, Tetsuro. In doing so, he discovered the most powerful of the Guyver's weapons: the mighty Mega Smasher; in the first two OVAs, he was also able to kill Guyver II at this point.
After that, Sho began to realize that the situation he was now in was very serious, and also, that there was far more to it than what he had seen so far.
