When the kids return to Japan accompanied by Judy, they are taken to an abandoned research facility where Mr. Dickenson had once worked on a similar rock with his old partner, Dr. Zagart. Like the one that was stolen from the BBA, this rock was covered in mysterious writing and possessed strange powers. Unfortunately, it too disappeared, along with Dr. Zagart who was never seen again. After a battle with Kenny and his new “Einstein” Beyblade, Tyson realizes he still has to learn how to control his new, ultra-powerful Beyblade, Dragoon V2. While practicing down by the river, he is challenged to a battle by Ozuma and the Saint Shields. Tyson accepts and manages to hold his own until the entire Saint Shields clan gangs up on him. It looks like all is lost until a mysterious stranger steps in to save the battle and the day. But the Saint Shields vow to return and fulfill their mission to capture and seal the four Bit-Beasts.
