An amazing assembly of powerful Pokémon and Trainers—including the Kalos Gym Leaders and two Champions—have come to help our heroes stop Team Flare! This teamwork allows Ash and Alain to rescue Chespie from inside the Giant Rock, and it seems to be defeated...until it rises once again, under Lysandre’s control.

Things seem hopeless until Squishy persuades the other Core to join the fight. The two of them merge together to become the titanic Zygarde Complete, which puts a stop to Lysandre’s plan once and for all.

Finally, it’s time for Squishy and Bonnie to say their goodbyes—but they’ll always remember their unwavering friendship that helped save the world!

Everyone heads towards the Giant Rock using the Shuriken to know where to go in order to rescue Chespie as Mairin, Bonnie and Serena look on. It uses vines to attack but Pikachu and Charizard counter with Iron Tail and Flamethrower. More vines attack as Malva, Blaziken Mask and Alain order their Pokémon to use Flamethrower. Valerie and Olympia assist as Ash and Alain make their way through the vines but Valerie is soon captured but she insists they continue. Korrina and Lucario stop a vine from attacking Greninja but are also captured but insists they continue as Ramos and Gogoat also buy them time before being captured. Alain and Ash are captured by vines but Viola frees them with Vivillon using Solar Beam. Grant has Tyrunt attack the vines with Rock Tomb creating a wall but more vines attack Viola knocking her into Grant, capturing them. Ash and Alain climb up the wall as more vines attack but Wulfric has Abomasnow use Ice Shard on them to freeze the vines and orders them to hurry up as Abomasnow is knocked away. Their friends go ahead to clear a path with Malva has Houndoom use Dark Pulse, Professor Sycamore has Garchomp use Dragon Rage before being captured along with Malva in the vines. They tell Ash and Alain to keep going as Ash vows not to let them down. Watching with Serena and Bonnie, Mairin hopes that Chespie will be OK as Clemont has Chespin, Luxray and Bunnelby attack the vines with Pin Missile, Swift and Mud Shot helping to clear a path.

As Alain and Ash approach the centre, a vine comes up to attack but it is hit by Bullet Seed. Ash looks up surprised to see Team Rocket in the helicopter with Gourgeist having launched the attack. Jessie tells Ash to not just stand there but a vine comes up and attacks the helicopter which sends Team Rocket flying but Gardevoir uses Psychic to save them. At a Pokémon Center, Sawyer, Trevor, Shauna and Tierno watch the action unfold on TV as Diantha and Steven Stone assist with Gardevoir and Metagross as they use Psychic to wrap the attack vines. They continue to attack the vines but Steven and Diantha find themselves trapped as Blaziken Mask and Blaziken are attacked. Squishy and Z2 watch with Z2 surprised that they are continuing the fight as Squishy tells Z2 that from watching the humans, not all humans are bad. Reaching the centre, Ash orders Pikachu to use Electro Ball and Greninja to use Water Shuriken as Alain orders Charizard to attack with Flamethrower. The attacks are blocked with vines but with support and determination, they break through and enter the rock. They spot Chespie lying overhead and Alain goes to free Chespie only for crystals to block his path as Ash promises to cover Alain as best as they can whilst he goes to free Chespie. As another crystal goes to attack, Ash orders Pikachu to use Electro Ball and has Greninja use Cut which cut through the crystals. Outside the rock continues to move as Serena goes to have Braixen, Pancham and Sylveon attack, the vines surround them and a vine goes to attack Mairin. As Alain nears Chespie, another crystal looms but Ash orders Greninja to use Water Shuriken which breaks the crystal. As more crystals go to stop Alain, he reaches Chespie. Outside the vines are about to hit Mairin when they stop and the rock stops moving. Ash and Alain along with their Pokémon emerge from the rock having freed Chespie. Everyone looks on pleased as the crisis has been averted.

Mairin hugs her Chespie who is still unconscious and thanks Alain for his work. Steven says all they have to do now is to destroy the rock. As Team Rocket films, all of their Pokémon launch an attack on the rock which knocks it down. Ash wonders if it has worked but the rock recovers as Lysandre appears vowing to still destroy the world. Lysandre has the rock launch an attack at the group but Valerie has Spritzee use Light Screen which minimizes the damage. As everyone recovers from the hit, Bonnie and Clemont are surprised when Blaziken Mask's mask comes off revealing that he is their father. Meyer has been injured but insists he is alright as the giant rock begins moving forward. Alain wonders how they can stop it as Clemont points out the device on Lysandre's wrist and Alain knows they have to destroy it. As everyone prepares to fight, Z2 notes that they are actually prepared to fight as Squishy informs Z2 that neither humans nor Pokémon will give up as Z2 feels they are too weak as Squishy says that together, they real strength lies in working together, feeling for each other and the power to believe in themselves and find the will to succeed as the rock launches another attack that sends them all flying. Seeing this, Z2 decides to believe in them as they jump down from Bonnie's grip, Bonnie moves to go after them but Meyer stops her as the Cores confront the rock, they call on every cell in the world as everyone watches as they become Zygarde Complete Forme. Olympia seeing this recognises the deep green eyes from her prophecy as Lysandre notes that they hid this forme from him and confronts it, saying it must have seen what this world is like and wonders what could be left to defend. Zygarde states this world belongs to the others and have protected them. The rock launches another attack which is countered by Dragon Pulse. The rock sends more vines towards Zygarde who dodges before attacking with Extreme Speed. Seeing their chance, Ash and Alain order Pikachu, Greninja and Charizard to use Thunderbolt, Water Shuriken and Flamethrower on Lysandre causing the device to fall of his wrist. Zygarde manages to break through the rock with Extreme Speed before attacking the rock with Core Enforcer which destroys it (with Lysandre, who refuses to accept he has been defeated, falling into the explosion) ending the crisis once and for all as those watching on TV cheer.

Diantha thanks everyone for their work as Steven wonders what became of Lysandre but Malva doesn't care and heads off, telling Steven to leave Team Flare to her to clear up before turning herself in to Officer Jenny. Chespie awakes from its coma leaving Mairin happy as she thanks Alain for his help who is pleased that Chespie is safe and asks Mairin to forgive him. Zygarde approaches Ash and his friends as Squishy thanks Bonnie for looking out for it before restoring order to the world, removing all the vines from Lumiose City and causing the red sky to disappear. Zygarde then disassembles, leaving Squishy and Z2 floating in the air. Chespie approaches Squishy who remembers that Chespie freed him from Lysandre Labs and expresses its gratitude. Squishy thanks Bonnie for taking it on a journey, allowing it to see that humans could be trusted to protect the world. Bonnie realises that Squishy is saying goodbye, and Squishy confirms it must leave to restore its energy. Squishy and Z2 rise into the sky, sharing a fond farewell with their friends as they both disappear into the sky with Bonnie telling Squishy how much it means to her. Just after they leave, the sun rises over Ash, Alain and their friends who all helped to save Kalos and the world from Team Flare.

The title card segment focuses on Ash for this episode


  • When Serena, Bonnie and Mairin run closer to the Giant Rock, Serena's Pancham and Sylveon can be heard but their mouths don't move.
  • Shortly after Ash and Alain enter the Giant Rock, Alain isn't wearing his Mega Ring.
  • This episode states that all of the Zygarde Cores and Cells from across the world are required in order to achieve Complete Forme. However, in the movie Volcanion and the Mechanical Marvel, Squishy was able to assume Complete Forme without all of them, albeit temporarily.

Dub edits

  • When Lysandre first returns to take control of the Giant Rock, in the original version he states that the countdown to the destruction of the world continues and that he will destroy the world even if it costs him his own life. In the dub, the first portion of this line is removed completely, and the second portion is rewritten to have Lysandre say he will destroy the world even if he is stopped.
