All for the Love of Meloetta! (Japanese: 歌えメロエッタ！愛の旋律！！Sing, Meloetta! The Melody of Love!!) is the 85th episode of the Best Wishes series, and the 742nd episode of the Pokémon anime. It is first aired on June 21, 2012 as the first episode of Best Wishes! Season 2 and in the United States on October 27, 2012.
Basking in the glow of his eighth Unova Gym badge win and guaranteed entry into the Unova League, Ash soon discovers that it won’t be taking place for three months! But our hero is determined to make the best of his time until then with lots of serious training—starting right after they try Virbank City’s famous Bearticone, at Cilan’s recommendation.
In line for the frozen treat, Ash spots a familiar face: it’s Cynthia, the Champion of the Sinnoh region! She’s been invited to participate in an exhibition match at the upcoming Pokémon World Tournament Junior Cup in eastern Unova, and Ash, Iris, and Cilan decide they want to compete as well.
Meanwhile, Team Rocket has been tracking Meloetta, the Mythical Pokémon that has been secretly following Ash ever since he rescued it at Pokéstar Studios. The villains try to capture Meloetta, injuring it in the process, but it manages to escape without a trace until our heroes and Cynthia find it and nurse it back to health. Meloetta shows its gratitude with a beautiful song before vanishing again.
Once Meloetta is safe, Iris finally overcomes her shyness to challenge Cynthia to a battle! Iris has heard about the Champion’s powerful Garchomp, and because she and Axew rarely meet another Dragon-type Trainer, it’s an exciting opportunity. Cynthia agrees, and though Axew is outmatched very quickly, it does learn how to use Giga Impact in the heat of battle!
It’s time to board the seaplane with Cynthia, and our heroes are unaware that they’re under observation by Team Rocket—and Meowth has spotted Meloetta following Ash onto the plane. Team Rocket quickly makes plans to intercept Ash and the others in Undella Town, and Cynthia tells Ash an old friend is waiting for him there as well. And sure enough, as the plane descends, Dawn and Piplup are there to meet it!
After having won his eighth and final UnovaGymBadge, Ash and his friends are at the Virbank CityPokémon Center, where Nurse Joy informs him that the Unova League Conference is still three months away. Cilan suggests they tour the city and get a famous Virbank delicacy, the Bearticone ice cream cone. Cilan takes them to a set of steps where an iconic scene from a famous film took place involving a Lilligant eating a Bearticone on the steps. However, a sign forbids eating Bearticones on the steps, so the group decides to go somewhere else. They turn to a Bearticone ice cream stand, where they meet Cynthia, the Champion of the Sinnoh region. Apparently, Cynthia is in Unova to enter the Pokémon World Tournament Junior Cup taking place in Lacunosa Town. Once they hear that not only will they get to watch Cynthia battle firsthand, but the winner of the tournament will get to battle Alder, the Unova Champion, Ash and his friends decide to participate. Together with Cynthia, they set off towards Undella Town in Cynthia's truck.
Team Rocket have followed Meloetta to a grassy field outside Virbank City. They can track their target thanks to the anti-cloaking goggles given to them by Dr. Zager. Jessie and James release Woobat and Yamask to use Air Cutter and Shadow Ball on the bush Meloetta is hiding in, exposing the Mythical Pokémon. Meowth fires an electrified net at the escaping Meloetta, but it falls short and just grazes its target. Meloetta falls to the ground after being electrified and rolls off of a short cliff into more bushes. Having lost sight of Meloetta yet again, Team Rocket begin looking for some way to get down to it.
Ash, Iris and Cilan are riding in Cynthia's truck when the weak and vulnerable Meloetta suddenly appears right before them on the road. Cynthia stops in time, but Meloetta collapses from heavy injuries. Ash then recognizes it as the Pokémon he saved in An Epic Defense Force! and Cynthia identifies it. Ash lays Meloetta on a sheet and Cynthia sprays its chest wound with a Super Potion. She then has Iris and Cilan get an Oran Berry while she and Ash go get some ice to lower Meloetta's fever, leaving Pikachu to watch Meloetta. They arrive at a river and Cynthia has her Glaceon use Ice Beam on the river to freeze part of it. She returns Glaceon and they collect the ice.
When they return, Ash puts the ice under Meloetta's head. Cynthia then gets a phone call to handle an apparently serious matter, so Ash and Pikachu are left alone. As Ash wipes Meloetta's head with a damp cloth, it awakens briefly and is happy to see a familiar face be its caretaker. Ash's Oshawott suddenly comes out of his Poké Ball and instantly develops a crush on Meloetta. After some time, the ice melts, so Ash has Oshawott look after Meloetta while he and Pikachu go get more ice from the river.
Meanwhile, Iris and Cilan have found an Oran Berry tree on the top of a cliff, but Cilan tells her that it's too dangerous to climb. Instead, Iris has Emolga ride an updraft to get to the tree and grab an Oran Berry branch. As they return, they see Ash and Pikachu collecting and crushing ice, so Iris sends Emolga ahead to give the Oran Berry to Meloetta.
Emolga finds Oshawott flirting with Meloetta, but a sudden gust of wind sends her crashing uncontrollably into Oshawott's head, knocking them both out. The Oran Berry rolls over to Meloetta, who wakes up, takes it, and flies away. When the gang returns, Oshawott and Emolga have awoken and begun fighting. A soothing voice nearby sings a song, calming the two down and giving everyone else a pleasant feeling. Cynthia then arrives and explains the pacifying power of Meloetta's song. After its performance, Meloetta vanishes. Cynthia tells Ash that the pressing matter which she had to attend to was that she had forgotten her change at the ice cream stand... which dismays Ash. Shortly thereafter, Iris musters up the courage to challenge Cynthia to a battle, which she accepts. Meanwhile, Team Rocket spot Meloetta and continue their pursuit.
For their battle, Cynthia will use Garchomp and Iris will use Axew. Iris starts the battle with Scratch and then Dragon Rage, but neither deal any significant damage. Cynthia then has Garchomp use Dragon Rush and then Draco Meteor, each hitting Axew with terrifying force. However, Axew refuses to give up and immediately learns Giga Impact while in a rage. Axew briefly levitates off the ground before charging rapidly at Garchomp and doing some damage. Garchomp then uses Brick Break while Axew is recharging, but Cynthia orders it to stop since it would obviously finish Axew off. She and Iris agree to end the battle here.
Team Rocket are searching for Meloetta near the dock just as Ash, Iris, Cilan, and Cynthia arrive and board the seaplane for Undella Town. Meowth observes as Meloetta follows them into the plane while invisible, so Jessie says that they must contact Dr. Zager and get to Undella Town before they do. Cynthia then tells Ash that he has an old friend waiting for him in Undella Town. From Cynthia's villa in Undella Town, Dawn and Piplup see their seaplane.
Unlike the previous episode, Professor Oak did not appear at the beginning of this segment.
Viewers could call one of three phone numbers to hear an answer from either Jessie, James, or Meowth. Ten random callers among those who picked the Team Rocket member with the most callers won a Nintendo 3DS.
The scene that Cilan describes from Princess Pokémon's Holiday, with the princess (Lilligant) eating a Bearticone on the steps, is a reference to the romantic comedy film Roman Holiday. The character standing next to the princess also resembles Gregory Peck's character from the movie.
