Sean Barker: The Guyver Unit. It's been a year since the alien armor invaded my body and became a part of me. A year since I first became the Guyver and destroyed the Chronos Corporation and their shape changing killers, the Zoanoids. Now Chronos is gone. But the Guyver stays in me. Calling me to fight. To kill.
