When Keldeo brashly attacks Kyurem, it dominates the battle, eaisly deflecting or dodging his attacks, and he ultimatley cuts off Keldeo's horn with Shadow Claw. When Terrakion attacks Kyurem with Hyper Beam in an attempt to defend Keldeo, Kyurem deflects it then freezes allthreeMusketeers with Ice Burn. Keldeo falls off a cliff and then flees, and Kyurem gives chase.
Keldeo stumbles on the train that Ash & hisfriends are on, while Kyurem and his Cryogonal henchmen catch up attack Keldeo, but they are repelled by Ash & his friends.
Kyurem pursues them and attacks them several times, only for them to be distractions made by Iris & Cilan. The two face off where they first met, and, despite Keldeo giving it his all, Kyurem retains the upper hand. After a lot of battling, Keldeo is hit by a Freeze Shock that was meant for the Musketeer trio. Because of the electrical element to the attack, it overwhelms Keldeo and Kyurem wins the battle. Instead of finishing the job, however, Kyurem respects Keldeo's courage and states that it was better to lose a battle than to lose one's friends.
