Pokémon Chronicles (2002)

The Search for the Legend

Richie is on the S.S. Anne when a school of wild Gyarados block the waters ahead. The crew is about to take the long way around, but a grizzled Trainer named Silver orders his Salamence to send the Gyarados packing so the trip can continue. But Richie thinks there's something suspicious about the two researchers with Silver, especially when the ship docks at an evacuated volcanic island and Richie sees the three of them sneaking onto the shore.
