Description
Pikachu serves as Ash Ketchum's primary Pokémon partner, accompanying Ash, Iris, and Cilan on their journey. During a train sequence, it interacts playfully with Oshawott, Axew, and Scraggy. Pikachu later detects the injured Keldeo on the train roof, alerting the group.

When Kyurem attacks the train, Pikachu battles the Legendary Pokémon, launching Thunderbolt. It later uses Iron Tail and Electro Ball against Cryogonal minions during the pursuit through Roshan City. Demonstrating loyalty and protective instincts, Pikachu fights alongside Ash to shield the group from Kyurem's assaults.

Pikachu enters the Full Court mine with Ash to rescue the frozen Swords of Justice, remaining active outside its Poké Ball throughout these events. Its role centers on supporting Ash and his friends during the conflict between Keldeo and Kyurem, participating in battles and strategy execution without directly confronting the titular Legendary Pokémon.
