Pokémon S16E10 - Cameron's Secret Weapon!

It's time for the quarter finals of the Unova League and Ash is facing up against his friend Kotetsu. Ash gets a shock when Kotetsu sends out the massively powerful Hydreigon. With the battles now being 6 VS 6 battles in this round, Ash faces a bigger challenge than he has had so far in the league. In addition to that, when Riolu starts to be in play, it manages to climb on top of Ash's Pokémon and do severely damage while on them. Will Ash manage to overcome the odds and defeat his friend?
