Pokémon: Black & White In The Shadow of Zekrom!

Ash, Pikachu, his mother and Professor Oak head off for a vacation in the Unova Region. A strange black cloud forms overhead and hits Ash’s Pikachu with a lightning bolt. After meeting up with Professor Juniper Ash encounters Trip – who is beginning his Pokemon League challenge with the Grass-type Pokemon Snivy. In a practice match against Trip, Pikachu cannot use Electric moves – which Juniper attributes to the lightning bolt caused by the Legendary Pokemon Zekrom., Pikachu is struck by lightning after arriving in the Unova region with Ash.
