Ash is finally training for the Pokémon League by battling Brock in a rocky valley, with Pikachu pitted against Vulpix. Pikachu is about to use Thunderbolt and Vulpix is about to use Flamethrower, when Jigglypuff suddenly appears in-between them. At Ash and Brock’s command, Pikachu and Vulpix fire their attacks in a different direction, destroying a rock wall. As Ash and his friends walk closer, they see that they have uncovered the entrance to a temple, as well as a gigantic dÅtaku bell. Brock finds an ancient artifact in the rubble, but it is suddenly taken by an archaeologist named Eve. She reveals that she and the other archaeologists with her are digging up artifacts related to the ancient city of Pokémopolis, a civilization that was supposedly destroyed in a single night. A professor brings themanother artifact, this one resembling a spoon with similar markings to the earlier artifact, and reveals to the group that Eve is actually a young genius who’s been an expert on all things Pokémopolis since she was six, much to their surprise. A flustered Eve pushes the professor out of the tent before showing the group an ancient tablet, which says that two great powers of destruction will fight and destroy the world, and no human knows the secret to stop them.
