Bio Boosted Armor Guyver

It all started when Sho Fukamachi, a high school student, found an alien artifact, Unit-G. Accidentally activating it, the Unit-G bio boosted Sho into Guyver I. Ever since Sho became Guyver I, a secret society, Chronos, began to hunt Sho and anyone close to him in order to retrive the lost units. Sho's life changed ever since that fateful day.

This is my personal favorite manga series. Recently, a new anime series been released of Guyver. Even though there was an anime release back in the early 90's, the 2005 release is more accurate as it follows virtually every chapter released on the mangas and novels.
