KAI Team: Bladebreakers When Kai first appears, he is portrayed as a cold hearted competitor and the ultimate nemesis of Tyson. As the leader of the Shell Sharks, he and his gang use their superior skills to win (or should we say steal) their competitors’ Beyblade equipment. But after Tyson challenges him to a battle, the two become team mates. Kai’s Bit Beast is Dranzer and his fighting style is vicious. He has a ‘take no prisoners’ mentality and likes to keep his battles short, leaving opponents wondering what hit them.
