Эп. 48: Кай встречается с Сергеем в финале чемпионата мира, сопротивляясь тёмному предложению Вольтера.

48

The World Championship Finals are about to begin and Kai insists on Beybattling first, hoping his knowledge of the Neo Borg will give him an advantage over the Neo Borg' first fighter, Sergei. But in the first set of the best-of-three match, Seaborg, Sergei's whale Bit Beast, uses the water in the Black Sea Bowl to create a tsunami, which overwhelms Dranzer. Kai is desperate for victory and Voltaire makes him a tempting offer: the power of Black Dranzer in exchange for betraying his friends and stealing their Bit Beasts. Kai puts Black Dranzer's Bit chip in his beyblade, but he unleashes Dranzer instead and launches his special attack towards Sergei's Wolborg. However, his power is not enough and he loses the second round, with Dranzer being captured next. Despite Sergei's victory, Voltaire is angry and vows to destroy Kai and his team mates for betraying him and not using Black Dranzer. (Source: Wikipedia)
