Pokémon Ranger and the Temple of the Sea

Satoshi and his companions become lost in a desolate wasteland, eventually stumbling upon a Water Pokémon Show led by Hiromi, a descendant of the Water People. Hiromi shares the legend of the Water Temple Akuusha, a hidden underwater sanctuary containing the Water Crown. A Pokémon Ranger named Jack Walker, secretly tasked with protecting the egg of the water Pokémon Manaphy, the "Prince of the Sea," appears. Satoshi, his friends, and Hiromi join forces with Jackie to transport the egg to the temple. Their journey is threatened by Phantom, a pirate who seeks the Water Crown to conquer the world. The Rocket-Dan also get involved, forcing Jackie to use his Capture Styler. The egg soon hatches, revealing Manaphy, and the quest to reach the Water Temple Akuusha begins.
