Chapter Summaries

After Team Flare’s base was destroyed and Z2 escaped, Lysandre ordered his executives to find it with help from Hunter K. In the wilderness, Z2 stumbled into Xiaoyun’s camp, where Shaymin’s Aromatherapy revived it, and Xiaoyun recognized the weakened Pokémon and offered help.

• Lysandre berated Aliana, Mable, and Xerosic for losing Z2 and destroying Team Flare’s base, then ordered them to enlist Hunter K and recapture it.
• Xiaoyun’s Pokémon relaxed and trained in the wilderness while Sirfetch'd found an unfamiliar green blob on the grass.
• Shaymin used Aromatherapy on the blob, which sprang to life and clung to Shaymin for its restorative scent.

• Z2 sought more of Shaymin’s energy, but Piplup drove it back with Bubble Beam.
• Xiaoyun calmly identified Z2 as Zygarde and offered it healing and Pokéblocks.

Diancie left the Diamond Domain with three Carbink guards to seek Xerneas before the Sacred Diamond failed, but thieves and a rival captor pursued her. Meanwhile, Xiaoyun and Dawn joined Steven and Paul on a journey to investigate strange energy in Hoenn, and the two groups collided when Diancie was captured in a forest.

• Diancie told Xiaoyun and his companions that the Diamond Domain faced destruction unless they found Xerneas within three days, and Dace explained that Marilyn was pursuing Diancie to exploit her diamond-creating ability.

• Diancie tried on several outfits with Dawn's help, and the two formed a close friendship as Steven praised their choices and Paul kept watch.
• The group rested at an outdoor dessert shop, where Diancie thanked them for their kindness and everyone enjoyed a relaxed afternoon together.

After Steven and Xiaoyun thwarted their attempt to take Diancie, Riot and Marilyn met Argus and Millie in an abandoned warehouse. The four thieves agreed to cooperate, planning to lure Diancie to a designated location so Argus and Millie could use Yveltal, though each secretly intended to claim Diancie for themselves.

After Yveltal was defeated, Diancie restored the Diamond Domain’s Sacred Diamond, evolved into Mega Diancie, and joined Xiaoyun’s group. Their trip to Hoenn was interrupted by the appearance of Primal Groudon, and at Devon Corporation they learned that Primal Kyogre had awakened as well.

• Kyurem defeated Yveltal, Xerneas agreed to guard the Cocoon of Destruction, and Xiaoyun’s group delivered Argus and the other thieves to the police.

• Alain’s Charizard attacked Kyogre with Flamethrower, but Kyogre’s Primordial Sea nullified the move and sent Charizard flying with a tail strike.

• Lysandre launched flashbangs and a capture net to seize the giant rock, but Xiaoyun used Sceptile and Darkrai to send it through a spatial gate to the Tree of Beginning.
• After Claire reported that the rock had vanished, Lysandre blamed Rayquaza and ordered Mega Gyarados and Pyroar to attack it.
• Mewtwo demanded a battle after sensing the rock's power, so Xiaoyun brought Mega Mewtwo X to the battlefield and pointed it toward Rayquaza.

• Kyogre fled into the ocean and Groudon walked away as the crisis ended, leaving Lysandre defeated and the giant rock missing.

• Wallace and Steven joined Xiaoyun, Dawn, May, and Drew for a meal, where Dawn stood and challenged Wallace to a battle under Pokémon Contest rules.
• At Rustboro City's public battlefield, Dawn sent out Diancie against Wallace's Milotic, and Wallace used elegant Contest techniques to counter her attacks.
