Plot
A test type Zoanoid escapes from the Cronos Corporation with three Guyver Units. Cronos soldiers pursue the test type into some woods to recover the units from him, but when they corner the test type, he detonates a bomb he had with him. The Guyver Units are scattered in the blast. One of the lost Guyver Units, known as "Unit I", lands near two young high school students, Shō Fukamachi and Tetsurō Segawa. The second one is retrieved by Cronos and merges with Oswald A. Lisker to become the second Guyver later on. The final unit falls into the hands of Agito Makishima, who merges with it at an unspecified time. Shō accidentally activates the unit which then painfully merges with him. Over time, Shō learns more about the Guyver and its abilities. The Guyver is virtually invulnerable, with its only weak point being the Control Metal. With this part intact, it can rebuild the host from their data it stores within, but if this part is critically damaged, however, the host will be eaten alive by the unit and perish. This is disconcerting and Shō starts to question whether he will ever be free from the Guyver. The situation gets worse with the fact that Cronos is continuously sending more and more powerful Zoanoids to retrieve the Guyver. This makes it increasingly difficult for Shō to protect his vulnerable friends. As the story progresses it also takes a startling turn, in which Cronos succeeds in taking over the world and reshaping it according to its ideals. The Guyvers are then labeled to the public as a "vanguard of alien invaders".
Guyver: Out of Control is a 1986 short horrororiginal video animation based on the manga. It was produced in Japan by Bandai, Studio Live, Network, Animate and Movic and in association with AIC, Artland, Studio Victory, Wave and Only For A Lite. It was released in the U.S. and Canada in 1993 by L.A. Hero under the Dark Image Entertainment label. It has since been out of print in North America. The story follows high school students Shō Fukamachi and Mizuki Segawa who accidentally discover one of three Bio Booster Armor units stolen from the Chronos Corporation. When Shō and Mizuki are attacked by a Zoanoid, the unit comes into contact with Shō and bonds with him, transforming him into Guyver I and promptly destroying the Zoanoid assailant. Meanwhile, a female Chronos agent named Valcuria acquires a second unit and becomes Guyver II. She then abducts Mizuki in order to challenge Shō for the Guyver I unit. On Anime News Network, Justin Sevakis called it an "extremely dated piece of pulp that still somehow manages to be fun".
