Kai's Royal Flush (カイのリベンジバトル, Kai's Revenge Battle) is the forty-third episode of Beyblade: V-Force.
Kai is given a brand new Beyblade crafted for him by Kenny and longs for a rematch against King and Queen.
Doctor K is also after them and tracks the duo down to offer them a chance to team up with her so they can capture and wield the power of the four sacred bit-beasts together. The pair blow her off, interested only in their quests for stealing the perfect Beyblade parts.
Eventually, Kai is informed that both are fighting kids for their parts. Kai heads for the location and demands them a revenge. The battle is fierce, and eventually Kai Dranzer throws King's Ariel towards a tree, which falls between them. Dranzer is left spinning, but the pair disappears, meaning the fight has no outcome. They are later seen at Doctor K's car and learn that Dranzer was one of the sacred bit-beasts.
Later, Tyson advances to the finals of the championship and the team learns that King and Queen have entered the finals. Kane and Jim, the Psykick's ex-recruits that battled the Bladebreakers at the Psykick tower, are back in town and are also competing in the finals while Goki and Salima travel around the World to teach kids how to Beyblade.
At Psykick's lab, Gordo is chosen as Zeo's partner at the tournament and is given Orthros, a two-headed canine bit-beast from the rock.
