Pokemon Movie 15: Kyurem vs. Seikenshi

Keldeo dreams of joining Cobalion, Terrakion, and Virizion as one of the Swords of Justice. Impatient to prove himself, he challenges the immensely powerful Kyurem before he is ready and lies that he is already a Sword. The fight ends in disaster, leaving his mentors trapped in ice and Keldeo fleeing in fear.

Ash, Iris, and Cilan find the injured Keldeo and agree to help him. Kyurem pursues them relentlessly, not because it seeks conquest, but because the unfinished challenge still stands. To free his friends, Keldeo must stop running, admit his fear, and return to the battle with a truer understanding of courage.
