After hearing Gym Leader Olympia’s ominous prediction, Champion Diantha visits our heroes just as Ash and Greninja are doing some special training. To find out more about the bond they share in battle, Diantha challenges them, and Ash jumps at the chance!

Diantha’s Gardevoir easily evades every hit…until Ash and Greninja begin to merge. Gardevoir has to Mega Evolve to keep up, and the bond between Ash and Greninja intensifies like never before—until they both pass out!

Diantha promises to learn more about this bond and how it might relate to Olympia’s prediction. After his battle with the Champion, Ash is even more fired up for the Kalos League!


The episode begins with Olympia speaking with Diantha about her vision of the future crisis of Kalos. When Diantha asked about "Those deep green eyes", Olympia showed her an image of Zygarde, which made Diantha impressed by recognizing it.

Then is shown a scene with Ash and his Greninja stretching and racing each other, with Ash believing he could master the Ash-Greninja form if he "becomes" Greninja. They stay at the same speed until Greninja starts jumping from branch to branch, with Ash mimicking Greninja, but he fell from a branch and Greninja helped him to stand up. Serena, Clemont and Bonnie are waiting Ash and Greninja on a glade, with Bonnie worried about Greninja's and Ash's delay, with Clemont finding the idea of "become a Pokémon" an absurd and Serena wanting Ash to not overdo with that idea. Greninja reached to the group first and Ash, very tired, reached last.

Then, Diantha reached the glade in a helicopter, jumping from it. Squishy was hiding in the bag. Ash asked Diantha why she was there, and she's says that she is there to find them and she says that she listened to Olympia's prophecy. Team Rocket is nearby, observing them. Diantha speaks about the Kalos Crisis and she shows an image of an island attacked by Team Flare's weapon. She mentions that's this its not the only place in Kalos with that state. She says that the danger mentioned on the prophecy refers to when Zygarde begins to act. She shows an image of Zygarde to the group and starts to explain its role. Team Rocket recognizes Zygarde as the Pokémon that Team Flare kidnapped.

Clemont remembers the prophecy and how Olympia says that they are involved somehow in the crisis. Diantha asks if something changed around them, and Bonnie comments about Ash's Greninja being amazing, and they explained her the phenomenon. Clemont remembered what Olympia said about them when Greninja was a Frogadier. Diantha asks Ash to show Greninja to her in a battle against her Gardevoir. Team Rocket start planning to steal Diantha's Gardevoir when it Mega Evolves. Diantha's notes the Battle Pulse Meter and asks about it, so Clemont explains how it works.

The battle starts, with Greninja trying to hit a few hits, with Gardevoir quickly dodging them. Diantha comments that Ash's Greninja is well created, but doesn't feel any difference on the others. So, she started to attack with a Shadow Ball and Ash tells Greninja to use Double Team to dodge the attack. Diantha responds by having Gardevoir to use a Shadow Ball sequence to destroy the clones. Ash says to Greninja to use a Water Shuriken sequence in return, bu was dodged by Gardevoir. Gardevior uses Moonblast, which was dodged by Greninja, but it was hit by the shock wave.

Ash helped Greninja to stand up and said that he had an idea. He told Greninja to use Water Shuriken, which was dodged and created a vapor cloud. It was used to distract Gardevoir, which was then hit by Greninja's Cut. Greninja transforms into its Ash-Greninja form. The camera shows an impressed Diantha. Team Rocket is impressed as well. Ash tells Greninja to use Cut, which was blocked by Gardevoir's Shadow Ball, but deals damage to Gardevoir. Diantha says to Gardevoir to use Shadow Ball, which was blocked by Greninja's Water Shuriken. Then Greninja goes towards Gardevoir using Cut, which was almost dodged, but Gardevoir was hit. Ash says to Greninja to use Aerial Ace on Gardevoir, but Diantha Mega Evolved it and the attack was blocked.

Ash says that the battle really started now and says Greninja to use Water Shuriken, the camera shows Ash and Greninja making the same movements while the attack is been executed. The attack was blocked by Gardevoir's Shadow Ball, so Greninja uses Aerial Ace, which was blocked by Gardevoir's Reflect. Greninja used Double Team and later Cut. Gardevoir used Reflect, but the protection was destroyed by Greninja's attacks. The water veil around Greninja was transformed in a Giant Water Shuriken on Greninja's back. It used its new Water Shuriken to attack Gardevoir. Gardevoir used Shadow Ball to block Greninja's attack, but failed and was hitted by the attack. Ash says to Greninja to use Cut, but both faints in the process. While Diantha is going to check if Ash is okay, Gardevoir was captured by Team Rocket, but Gardevoir with its "Max Power" was able to escape from Team Rocket's "Unbreakable Mega Ring" and used Shadow Ball to blast them off. Ash woke up looking for Greninja. She says goodbye to the group and to think about researching more about Ash and Greninja's power, for Kalos', Ash's and his group's sake.

It's shown a quick scene of Lysandre saying that it is time to go to the final stage and Ash promised to Greninja that they will become stronger and master their power as they prepare to leave.
