Shou and his friend, Tetsurou, stumble upon a strange orb-like mechanism, the Guyver Unit, in the woods. It physically bonds with Shou and turns him into the alien soldier, Guyver. His mission is to protect the Guyver Unit from the Japanese corporation known as Chronos. They are after it and two other units just like it. To retrieve the object, they send out vicious monsters known as Zoanoids. So no one is safe in Shou's life; not even himself.

The story of this anime is actually quite believable in that there is this secret corporation, called Chronos, that plans on obtaining world power (similar to the "Illuminati"). Unlike other anime that rely on magic and supernatural, this one is ...

Mixed Feelings
The Guyver Volume 1 is the first six of a twelve episode series loosely based on Yoshiki Takaya's manga. The anime has gained a huge cult following over the years.

I on the other hand just can't agree with that.

The Guyver is a sci-fi action series which in my view succeeds in two areas. This would ...
