As Ash prepares for his Gym Battle with Clay when he walks in the gym, he has another problem in his mind. Clay has no time for a gym battle because he said that he ran out of Revival Herbs which is the king of all healing herbs. So Ash and co. decided to go find Revival Herbs and the only place where they grow (given by Charles' advice) is the Island of Legend where the Kami Trio lives. As Ash and co. arrives to the island, the clouds darkens the atomosphere and wind and thunder appear in the sky. A local boy name Lewis comes by and tells them that Grass Pokémon aren't doing so good, and that the shrines of Tornadus and Thundurus are desecrated, when their wedges are smashed making them angry. The only Pokemon that can stop these two is the Abundance Pokemon, Landorus. Ash and co. decide to help Lewis and the other Grass-type Pokemons. Can they successfully summon Landorus to stop these mighty gods from destroying all of Unova?
