Battle B-Daman

Yamato, who was raised by cats until he was five, has only dreamt of owning a B-Daman and playing the sport. When his dream comes true and is given the legendary B-Daman, Cobalt Blade, will Yamato have what it takes to control it from those who wish to steal it from him?

In a rematch against Gray, Yamato learns how to better control Cobalt Blade. During the match, Bull's ""dark side"" makes his first appearance in order to steal both Cobalt Blade and Chrome Zephyr. It is up to Gray and Yamato to keep that from happening. Can Gray and Yamato put their differences aside to stop him?

Eager to B-DaBattle other B-DaPlayers, Yamato learns of the B-Coliseum, a place where all B-DaPlayers can play all sorts of B-Daman games. When he gets there he soon realizes that he still has a lot to learn about the sport. But when a mysterious member of the Shadow Alliance shows up, it's up to Yamato to put his skills to the test and stop the evil Battle Crow from destroying the B-Coliseum.

Ababa sends Wen and Li to take control of Cobalt Blade after Battle Crow's failed attempt. Yamato, Gray, and Bull run into Wen and Li on Delta Rock where they must B-DaBattle them in order to save Chrome Zephyr from a pillar of ice. If Yamato and Bull can't defeat Wen and Li, Gray will lose Chrome Zephyr forever. But things get a lot more difficult when both Wen and Li combine their B-Damans to form Bakurekuso.

Wen and Li win the match thanks to Li's cheating, and Yamato discovers Gray is a member of the Shadow Alliance. Yamato was in shock when he heard this, and he was very angry.

Yamato goes onward to find Armada, but, on the way, Yamato meets Terry, who follows Yamato to find Armada, but, the two keep getting in fights. When they made it to Armada, they were given a test. The test was to draw circles & triangles all over the place, even underwater! A swarm of paper bats put their abilities to the test as well as learning Rapid-Shooting, but, what will Armada's next challenge be?
