Ash almost falls off a cliff, but then Cameron saves his life. Cameron has a "great idea" and he gets out what seems to be a "map", which was a table cloth. As they continue heading down a road, it starts to rain and then they take shelter in a nearby cave. Realizing that they didn't have any food, Ash, Cameron and their Pokémon are hungry as Meloetta leaves only to come back with an apple. Meloetta leads them to an apple tree where they harvest the apples to bring them back to the cave to munch on them. After they ate the apples (and Cameron's Riolu hiccups adorably), they decide to stay the night in the cave until the rain stops. Ash and Cameron exchange their goals in life.

Ash continues to train at Cynthia's villa until Ridley (a member of an ancient civilisation dedicated to protecting Meloetta) and his Golurk hear Meloetta's song and come to take Meloetta back.

Before Ridley can take Meloetta home, Team Rocket assaults the group and capture Meloetta and summon up the ancient Abyssal Temple through its power and song. The heroes try to fend off Team Rocket, but with Giovanni himself present they are too strong.

With Meloetta in their possession, Team Rocket's Giovanni controls Tornadus, Thundurus and Landorus in their more powerful Therian Formes though use of the reveal glass unlocked by Meloetta's presence and Meloetta's song. Ash, Cilan, Iris, Cynthia, and Ridley do their best to free Meloetta and save the world from Team Rocket. But forces stronger than Team Rocket are present, and Giovanni soon finds himself not able to control himself and sets Tornadus, Thundurus, and Landorus on a path to destroy Unova rather than take it over for Team Rocket.

Learning that the Unova League will be held at Vertress City, Ash and his friends prepare for the tournament, but not before making a detour towards Iris' hometown, the Village of Dragons.

With the Unova League tournament over, Ash and company return to Nuvema Town to meet up with Professor Juniper and to tell Professor Oak about his results. Along the way, they meet Nanette who is going to see Juniper for her first Pokémon, and eventually chooses Tepig and asks to have her first battle with Ash. However, during the battle, a robot appears and it is piloted by a very familiar trio. Later, Professor Juniper gets a call from her father, who invites Ash and friends to visit him at the White Ruins, located north of Icirrus City.

On a boat heading to see ruins dedicated to Reshiram, Ash, Iris, and Cilan meet the mysterious boy calling himself N, who quickly befriends their Pokémon. However, when Team Rocket attacks the group once more and James's Amoonguss paralyzes Pikachu with Stun Spore, N's timely intervention helps turn the tide of the fight.

The group's boat arrives in Aspertia City, and they arrange to meet Cheren, Professor Juniper's acquaintance and the city's new Gym Leader. A teacher at the local Pokémon School, Cheren is lacking in confidence regarding his worth for the title, something Cilan - as a former Gym Leader himself - connects with him over. After misadventures in the Pokémon House on the school grounds - including a series of mishaps between Cilan, Pansage, and a flock of Ducklett - Ash has an unofficial Gym match against Cheren, Oshawott facing off against Herdier.

When Team Plasma scientist Colress uses his machine to draw out Pokémon strength, the controlled wild Pokémon attack the residents of nearby Floccesy Town.

Successfully freeing Braviary, N joins the group on their journey to the White Ruins.

Upon returning to Virbank City, Ash and friends meet Halsey who runs a rescue team consisting of his two Frillish, his Dewott, and his Watchog. Making his personal feelings on the idea of Pokémon putting themselves at risk for the sake of humans known, N's belief that Watchog (who seems ill-suited for the Team's risky endeavours) is being used as a tool causes an ideological clash between Halsey and N, but the two young men must put their enmities aside when a fire breaks out in Virbank City's Industrial Complex.

Ash and his friends come across the Kanto Fair, and seeing a Charmander perform on stage reminds him of his old friend Charizard. He tells Iris, Cilan and N about his and Charizard's history, with Misty and Brock making cameos during the tale. Professor Oak sends Charizard over, and after he meets Iris' Dragonite, the two trainers agree to have a friendly match. Ash's offer to let Charizard rejoin his team is met with approval from all parties involved.

Colress appears and tests his newly-advanced machine on Dragon-type Pokémon - first taking over a young trainer's Haxorus, and later Iris's Dragonite. As Ash and Charizard try to stop them, N puts himself in the crossfire, knowing the Pokémon should be friends and not fight.

After N is hurt by Colress's machine, two young women, Anthea and Concordia, come to save him. It is from these two girls that Ash and the others learn the truth about N's life, including his link to the evil Ghetsis.

Team Plasma's Colress convinces Team Rocket's Jessie and James to use his technology on Meowth to make him stronger, but it is all part of Colress's plans to test his Pokémon controlling device.

At the ruins dedicated to the Pokémon Reshiram, N steals the Light Stone from Cedric Juniper, and Ash's attempt to stop him ends with them separated from the others. Team Plasma move to attack the White Ruins while Team Rocket watch on in anticipation, and Iris, Cilan and Looker attempt to fight off the enemy forces.

Ash and N prepare to save Iris, Cilan, and Professor Juniper's father from the clutches of Team Plasma before Ghetsis can revive Reshiram, but their attempts to fight back are hampered by Colress's Pokémon controlling machine, forcing them all to call back their Pokémon. Pikachu gets hit by the machine's beam, which sways N into surrendering the Light Stone in exchange for its freedom just as Ghetsis arrives, ready to begin the ritual.

As the revived Reshiram quickly falls under Ghetsis' control, Ash and friends try to develop a strategy to stop Team Plasma. Looker convinces Team Rocket to help in the fight against the villains, while Ash and Pikachu aim to destroy the controlling machine, and N hopes to pacify the enraged Reshiram before it destroys the world in a righteous fury - akin to when it burned down Team Plasma's castle in the past.

With Team Plasma defeated once and for all, Ash decides it is time to go back to Kanto. Iris and Cilan decide to go with him to further their skills, and Professor Juniper charters all of them a cruise through the Decolore Islands on a boat with a mysterious crew. Once settled in their cabins, however, Ash finds that they are locked in and their Pokémon are not with them.

The cruise makes a stop on Honey Island, known for its colonies of the Honeycomb Pokémon Combee, Pupa Pokémon Kakuna, Stinger Pokémon Beedrill, and its honey-flavored cuisine.

As Ash and his friends prepare for the upcoming Marine Cup Tournament on board their new cruise ship, the group learns that Mrs. Ripple, a jewel collector, will display her collection after the tournament, but upon the tournament's conclusion she discovers that her rare Eye of Liepard has been stolen.

On Cave Island, Ash and his friends meet up with Clair, Gym Leader of Johto's Blackthorn City, who has come to the island to capture a different-colored Druddigon, but her Dragonite left without her. When they find her Dragonite, Iris's Dragonite takes an instant dislike to it and the two fight, hampering Clair's plans to find the different-colored Druddigon on the other side of the island from the port.

The appearance of Woodate Comet approaches, so Ash, Iris, Cilan, and Alexa go stake out the ruins where the legendary hero it is named after first spotted it. However, they must deal with several Ghost Pokémon and Team Rocket who are once again trying to capture Pikachu.

On another island, Ash, Iris, Cilan, and Alexa meet a boy named Tony who touches Alexa's Gogoat's horns, causing it to temporarily bond with him. They all help Tony meet his father on the other side of the island.

After being scolded by Iris, an ambush by Team Rocket starts to make Emolga wish she did not have to be with such strict trainers and fights on Team Rocket's side.
