Hyoga, the Cygnus Saint, travels to Asgard after having heard rumors of a conspiracy that has been transpiring there. Athena and the Bronze Saints are unable to contact Hyoga, and thus set forth to travel to Asgard and meet with the High Priest of Odin, Dolbar; for he may know the whereabouts of Hyoga. However, the gang will soon discover that what awaits them in the land of the Scandinavian Gods is much more than they bargained for!
Brains, blood, bravery, and a battler: a B’t is made up of each of these, and more. The next generation of robot, B’ts possess individual thoughts, great power, and are powered by one thing: blood. They obey only one person implicitly: the blood donor who awakened them. The Machine Empire has been hiding their creation, planning to use them in their quest for world domination. When Kotaru, a brilliant scientist, begins research along lines that would lead to B't, the Machine Empire kidnaps him to do their bidding. His brother Teppel pursues them, but is wounded in a battle with an old adversary. Beat and bleeding, Teppel's blood ends up wakening B't X, one of the most powerful B't who just so happens to belong to Teppel's teacher. Can Teppel convince X to fight with him and help rescue his brother?
Yet another one of Kurumada sloppy works, featuring lots and lots of repetitive action and lots and lots of plot holes.
It isn't all that bad, though, if you come to terms with the need of having a decent if not satisfatory script and enjoy a show where the main characters keep trashing goonies and bosses with the same attack over and over again...
