Seeing a video, Ash and Brock want to learn from Bruno, a member of the Elite Four. They, along with Misty, go to the mountains, but get chased by a gigantic Onix. Luckily, Bruno saves them, but after being told about their quest, Bruno does not have much secrets to share, but to capture the strongest Pokémon. Ash and Brock, along with Team Rocket, decide to capture the gigantic Onix, but they see it is much more to handle than it looks.
