So in the episode Pikachu is against either an Onix or a Steelix. The Pokemon used dig, and Pikachu then used thunderbolt into the hole that it dug into the ground, it sent giant pillars of lightning through the sky and shocked everyone in the arena at the pure power coming from Pikachu. I need to know where I can watch this without rewatching watching the entire series... It could be a movie too.
