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 atmosphere 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 when their sick since all of the Revival Herbs are dried up. However, the next day, as Ash and co. are doing the rain-making ceremony in order for it to rain, fierce Tornadus, the Cyclone Pokémon appear in such a rage and attack them due to the fact the shrines of Tornadus and Thundurus are desecrated, when their wedges are smashed making them angry as savage Thundurus, the Bolt Strike Pokémon appear from the raging storm as they battle fiercely for a very long time. The only Pokémon that can stop these two is the Abundance Pokémon, Landorus. Ash and co. decide to help Lewis and the other Grass-type Pokémon. Can they successfully summon Landorus to stop these mighty gods from destroying the island and all of Unova?
