Guyver: The Bio-boosted Armor

The Chronos Corporation, which has biologically created workers and troops who can instantly morph into formidable monsters known as Zoanoids, has dark designs for the globe. After taking a bag holding three devices Chronos was researching, known as the Guyver units, a test type Zoanoid, posing as an ordinary man, makes off with the objects. Soldiers from Chronos try to take the test-units type's back, but as they do, he triggers a grenade, killing himself and dispersing the Guyver units. Two high school students, Tetsuro Segawa and Sh Fukamachi, find one of the lost units. When Sh inadvertently activates the device, it transforms him into biological armor, enhancing all of his physical capabilities and equipping him with lethal weapons.
