Stopping the Rage of Legends! (1)

Ash tries to challenge Clay to a gym battle again but Clay refuses because he has to find some Revival Herbs for Driftviel City. He says if Ash can find some, he will battle him. Ash, Iris, and Cilan learn that they grow on Milos Island and head there to find some. Upon arriving on the island they find out that the herbs have all dried up for some reason. They meet Lewis who decides to pray to Landorus in order to save the island. However, things go unexpectedly wrong when the Legendary Weather pokémon Tornadus and Thundurus show up and begin rampaging.
