Good, but not particularly memorable in many ways
6 July 2007 | by dee.reidSee all my reviews

"Guyver: Bio-Booster Armor," an Anime' adaptation of the hit Manga created by Yoshiki Takaya, is a good effort but is not particularly memorable in many ways. I'm a huge fan of The Guyver, which you could consider the Japanese equivalent of Spider-Man because you can see the great amount of stress placed upon the hero in his battles against evil.

But "Guyver: Bio-Booster Armor" doesn't really hold you the way it should. I guess for the time it was on television (the late 1980s), it was good for what it was but when compared to the Manga itself and the far superior 2005 series, it simply pales because not a whole lot was done with it and plus it condenses much of the material, so it seems rushed and important, or key, character-driven scenes are lost and don't really connect with one another. The writing doesn't seem all that good either, so the dialogue seems a bit hokey (which could be because of the American dubbing). The animation is what "Guyver: Bio-Booster Armor" has working best in its favor, although that too seems dated.

The plot: high school student Sho Fukamachi accidentally activates an alien suit of armor, called a "guyver" unit, that transforms him into an exponentially enhanced mechanized warrior with a vast array of weapons, powers, and abilities. He becomes the quarry of the Chronos Corporation, a powerful conglomeration with designs on world power. Sho uses the Guyver's abilities to square off against Chronos and its army of shape-changing foot-soldiers, the Zoanoids, human mutants that can turn into monsters at will. He must use the Guyver to defeat Chronos and the Zoanoids while protecting his friends and family from their terrible onslaught.
