In a forest area by a large body of water, Lewis sees a dead Revival Herb and picks it up to examine it. Lewis crumples the herb up and notices in the sky that it is indicating a major disturbance. A bolt of lightning strikes Thundurus' obelisk. Ash and his friends head back to the Driftveil Gym to challenge the Gym Leader Clay. Clay tells them that he has no time for a Gym battle and must find a Revival Herb. Ash tells Clay that he will go and get the Revival Herb. Clay promises to battle Ash if he brings Revival Herbs to him. Ash, Iris, and Cilan head to the market and find Charles there. Charles tells them that he is there to pick up Revival Herbs, but the man who usually has them informs everyone that he cannot give them any. Charles suggests that they head to Milos Island where Revival Herbs are known to grow.
Once they arrive to Milos Island, they meet an older woman. They ask her about finding Revival Herbs, and she says that Lewis will be able to help them. They locate Lewis and ask him about the Revival Herbs and he brings them to his cabin. Everyone looks over to a bed and notices that Lilligant is really sick and lying down. Ash scans Lilligant with his Pokédex. Lewis mentions that like all of the Revival Herbs, the Grass Pokémon on Milos Island are also showing signs of being very sick. Lewis shows them a diagram of Thundurus and Tornadus fighting and causing major damage to the island. Another part of the diagram he showed was how Landorus stepped in and tried to stop fighting that was occurring with Tornadus and Thundurus. Landorus became injured and a Gothorita used its Psychic powers to send the Revival Herb to Landorus. After showing them the diagram, Lewis's Gothorita arrives inside the cabin and explains that there was no sign of Revival Herbs that weren't dead and shows Lewis a dead one. Lewis crumbles up the dead Revival Herb. Ash scans Gothorita with the Pokédex. Gothorita meets Pikachu and Axew, and it appears to really like Axew.
Lewis, Ash, Iris, and Cilan head to Landorus's obelisk. Lewis sets a fire and calls out for Landorus' help. Gothorita uses her Psychic powers to also ask Landorus for help. Suddenly a tornado-looking cloud appears and blocks Gothorita's attempt to communicate with Landorus. Tornadus breaks free from the cloud and appears. Tornadus attacks everyone with Hurricane, Air Slash and Hidden Power while Pikachu fights back with a Thunderbolt. Everyone runs away, but Cilan stays back to try to keep Tornadus from chasing after them, having Pansage use Bullet Seed on Tornadus. Lewis, Iris, and Ash head toward Tornadus' obelisk and discover that an important part had been destroyed. Lewis suggests that they should check Thundurus's obelisk as well. Meanwhile Pansage is really having trouble with Tornadus, and tries to use SolarBeam but Tornadus redirects it towards the others. Iris and Axew are sent flying but Gothorita saves them with Telekinesis.
Before Lewis, Iris and Ash can check on Thundurus's obelisk, a bolt of lightning strikes down on the obelisk. Thundurus appears out of the lightning and begins to attack with Thunder and Focus Blast. Thundurus heads towards the other island to confront Tornadus. Pansage is recalled after being hurt so badly from the battle with Tornadus. Tornadus and Thundurus begin fighting each other back and forth. Cilan suggests to Ash that he should try to stop them from attacking. Ash brings out Snivy and has her use Leaf Storm but Tornadus uses Hurricane to blow her back forcing her to grab onto Ash's arm with Vine Whip to land safely. Iris brings out Excadrill to battle them. Iris has Axew use Dragon Rage as well.
Meanwhile at a distance, Team Rocket is watching the whole battle take place. Team Rocket discusses how they will let the Pokémon wear themselves out and execute their plan when the time is right. Pikachu and Stunfisk try to use a combined ThunderShock/Thunderbolt attack to attack Tornadus, but Thundurus blocks the attack. Tornadus and Thundurus are both proving to be too strong and are damaging everyone's Pokémon. Lewis asks Gothorita to use her powers to try to communicate everyone's feelings to them, but it doesn't work and they keep attacking each other. The forest and the water start being affected by the disturbance. The battling causes a forest fire to form, and the water to form big waves. The rest of the people on the island show concern. Lewis tells Ash, Iris, and Cilan that they must try to summon Landorus and ask for its help. Lewis also explains to Iris that she is the only one who can ask for Landorus' help. In her shrine maiden outfit, Iris kneels down in front of Landorus' obelisk and calls out for its help. Gothorita uses its powers to lift the colored orbs and increase the strength of their cries of help. A light shoots up into the sky and hits the obelisk on the way down lighting it up. Tornadus and Thundurus continue their battle, and a shadow of Landorus is shown.
