Guyver: Dark Hero (1994)

Revealing mistake: When running towards the "bear attack", Sean activates the Guyver. Close ups of the armor attaching itself to his body show that's not really Sean as his arm and leg are both seen not moving even though he's running to where the attack is occurring.

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.

Trivia: Brian Simpson, who has three roles in this movie; Benny, Voker Zoanoid and Crane Zoanoid, also appeared in the first movie as a member of Craig's gang who attacks Sean.
