Die Blade-Breakers kommen zu den Weltmeisterschaften, um Zeo anzufeuern. Tyson ist sehr erfreut zu sehen, dass sein neuer Freund das Match gewinnt. Er bietet ihm an, sein Trainingspartner zu werden. Zeo willigt begeistert ein. In der Zwischenzeit feuert Dr. Zagart seine Mitarbeiterin Doktor K., die dabei ist, das stärkste Bitbeast der Welt aus einem Stein zu befreien. Zagart bringt die Aufgabe selbst zu Ende. Als Zagart nach Hause kommt, will ihm Zeo von seinem Turnier-Sieg erzählen. Plötzlich taucht Doktor K. auf und beschwert sich über ihre Entlassung. Da bekommt Zeo mit, dass sein Vater hinter den Machenschaften, den Blade-Breakers ihre Bit Beasts zu stehlen, steckt und ist vollkommen verzweifelt.
The Bladebreakers show up at the World Championship Tournament and go up into the stands to cheer on Zeo who's fighting in the preliminaries. Tyson is pumped watching his new friend who wins his first fight with ease. Later backstage, Tyson tells Zeo he's totally impressed and asks if Zeo would like to become his training partner. Zeo excitedly agrees. Meanwhile back at Zagart's lab, Doctor K is on the verge of removing the strongest Bit Beast in the world from the rock. But just before she can finish, Zagart enters and terminates her on the spot. That night at Zeo's house, his dad returns from work. The shocker here is, guess who his dad is? That’s right, Zagart!! And what's worse, an angry Doctor K shows up to confront her former boss in his house and as she does, Zeo overhears the entire conversation. Now Zeo realizes it's his dad who's been after the Bladebreakers' Bit-Beasts and his world is thrown into chaos!!
