• The mutated Carbink invited Chen Shi and the others to visit the Diamond Kingdom, and Chen Shi accepted.
• Chen Shi, Steven, Cynthia, and Diantha followed the Carbink into a dark cave, where diamonds became more numerous as they went deeper.

Chen Shi and his companions reached the Diamond Kingdom, where the Diamond Elder welcomed them. Chen Shi helped timid Victini join Jirachi and the Carbink at play, leaving the cavern filled with laughter.

• Chen Shi showed the antler fragment to the Carbink and identified it as a piece of Xerneas’s antler.

Chen Shi gave the mutating Carbink a fragment of Xerneas’s antler, completing her transformation into Diancie and offering hope for the Diamond Kingdom. He also hinted that Kalos’s legendary Pokémon would soon awaken.

• Diantha recognized the antler fragment as belonging to Xerneas and worried that Yveltal might also be real and nearing awakening.
• Steven compared Kalos’s life-and-death legends to Hoenn’s Groudon, Kyogre, and Rayquaza, then feared another regional crisis was coming.

• The Carbink transformed into Diancie, who declared that the Diamond Kingdom could be saved.

• The Diamond Elder asked whether Diancie could create a new Sacred Diamond, and Diancie produced the phantom image of one.

Diancie failed to create a true Sacred Diamond, leaving her and the Diamond Kingdom in despair. Chen Shi encouraged her to draw strength from her people, and Diancie resolved to keep going as their new queen.

• Diancie created ordinary red diamonds instead of a Sacred Diamond, despite exhausting herself trying again.

• Chen Shi challenged Diancie to stop blaming herself and reminded her that her people still trusted and relied on her.
• Diancie found strength in the Carbink's faith, promised to pull herself together, and Chen Shi told her that she alone could nurture life.

Chen Shi told Diancie that she had to understand the mysteries of life to create a Sacred Diamond and suggested seeking Xerneas in Oluans Forest. Mew persuaded Chen Shi to help search for the sleeping Xerneas, leaving him suspicious of Mew's motives.

• Mew recognized Chen Shi's words as ones Xerneas had once said to the First Diancie, while Diancie felt they held a deep significance.

• Diancie asked Chen Shi to take her to Xerneas, and Steven and Diantha eagerly supported the idea.
• Mew urged Chen Shi to search for Xerneas, saying it might reveal the truth behind the disappearance of Fairy-type energy, and Chen Shi grew suspicious of Mew's intentions.

Chen Shi agreed to help Diancie seek Xerneas, hoping to save the Diamond Kingdom and earn a tail feather from Mew as a reward. He left the kingdom with Diancie and his companions, while the Carbink watched them depart.

• Chen Shi gathered Jirachi, Togekiss, Mew, and Victini and set out with Steven, Cynthia, Diantha, and Diancie.
• Diancie looked back at the tearful Carbink and Diamond Elder, then resolutely left the Diamond Kingdom to seek hope for its future.

Chen Shi's group neared the place where Xerneas slept, but a powerful Beedrill ambushed them and tried to drive them away. Chen Shi suspected Beedrill was protecting Xerneas or the source of his strength, and continued forward with the captured Pokémon.

• Mew guided Chen Shi, Steven, Cynthia, Diantha, and Diancie through Oluans Forest while Jirachi stopped hostile Pokémon from attacking them.
• Jirachi sensed danger when a Champion-Level Beedrill nearly struck Chen Shi, and Jirachi restrained the attacker with Psychic power.
• Chen Shi scanned Beedrill and discovered that he had Legendary potential and had reached early Champion Level.
• Beedrill told Chen Shi to leave, claiming he had only meant to teach him a lesson, but Chen Shi refused.
• Chen Shi guessed Beedrill was guarding something connected to his strength or to Xerneas, then ordered Jirachi to bring Beedrill along as the group continued.

Chen Shi, Steven, Cynthia, Diantha, and Diancie found Xerneas sleeping in the form of a withered tree in Oluans Forest. Mew awakened Xerneas with a ball of rainbow light, and legendary Pokémon around the world sensed its return.

• Zygarde confronted the group, and Mew accused it of pretending to stop them despite wanting to see Xerneas too.
• Diancie took responsibility for asking Chen Shi and the others to find Xerneas.
• Mew teleported to the tree and merged a dazzling ball of rainbow light into it.
• The tree trembled as a rainbow pillar rose into the sky and life energy spread across the world, awakening legendary Pokémon.

Chen Shi and his companions witnessed Xerneas awaken, and she explained to Diancie that creating a true Sacred Diamond required understanding the mysteries of life. The group realized Chen Shi had already given Diancie similar advice, leaving him to insist that knowing a little about Pokémon breeding was reasonable.

• Chen Shi confronted Mew about the rainbow pillar, and Mew handed him a black-and-red feather instead of explaining.
• Xerneas emerged from the vanished withered tree, greeted Mew, and confirmed she had endured three thousand years of darkness.
• Zygarde confirmed Xerneas was unharmed, warned her not to fight Yveltal, and left after Mew teased it about its speech.

• Diancie asked how to create a true Sacred Diamond, and Xerneas said she had to understand the mysteries of life and nurture it herself.
• Steven, Cynthia, and Diantha recognized that Chen Shi had given Diancie similar advice, and Chen Shi claimed his knowledge came from being a Pokémon Breeder.

Chen Shi learned that Xerneas had suppressed poison from its battle with Yveltal using the Fairy Plate, causing Fairy-type energy to disappear until Xerneas awakened. As Fairy energy returned worldwide, Yveltal awakened and its black wind began turning the forest and its living creatures to stone.

• Chen Shi urged Diancie, Cynthia, Diantha, and their Fairy-type Pokémon to experience Xerneas's Fairy Aura, which helped Togekiss and Florges grow stronger.
• Xerneas asked Chen Shi to release Beedrill, and Jirachi lifted its Psychic restraint.
• Chen Shi asked why Xerneas's slumber had caused Fairy-type energy to vanish, and Xerneas explained that poison from its battle with Yveltal had forced it to use the Fairy Plate to suppress the poison.
• Xerneas said Fairy-type energy had returned throughout the world upon its awakening.
• Xerneas, Mew, and Jirachi sensed a threatening presence as Yveltal awakened and its black wind turned the forest's plants and creatures to stone.

Yveltal awakened and petrified much of Oluans Forest, but Zygarde stopped its death wind before it could spread farther. Xerneas revived the forest at the cost of its strength and began to fade toward sleep again, leaving Chen Shi and Victini ready to help it.

• Diantha feared that Yveltal's awakening would lead to a battle like the one in Hoenn, while Chen Shi remained confident that Zygarde would prevent a fight.
• Zygarde ordered Yveltal to stop, and Yveltal halted its death wind before facing Xerneas and flying away without fighting.
• Xerneas surveyed the petrified forest, told Mew it was going to sleep, and unleashed life energy that revived the forest and its Pokémon.
• Xerneas weakened and began fading toward its dormant form, prompting Chen Shi to ask Victini whether they should help it.
• Victini eagerly agreed to help Xerneas.

After Victini restored Xerneas, Xerneas offered Beedrill a chance to leave the forest with Chen Shi if Chen Shi could defeat him. Chen Shi shortened the challenge from three years to one, and Beedrill eagerly accepted, believing he would win.

• Victini used its power to stabilize Xerneas, restoring the forest and allowing Xerneas to remain active.

• Beedrill agreed to leave with Chen Shi if Chen Shi defeated him head-on within three years.
• Chen Shi declared he would beat Beedrill within one year, and Beedrill accepted the shorter deadline, expecting to win.

Chen Shi promised Xerneas that he would defeat and catch Beedrill within a year, then welcomed Diancie into his group as she searched for a way to create a Sacred Diamond. Jirachi teleported them back to Lumiose City, where Chen Shi and his Pokémon settled into their hotel.

• Xerneas left with Beedrill after promising to return in a year, and Chen Shi assured Steven and Cynthia that he could defeat Beedrill and catch it.

• Chen Shi, Cynthia, and Steven headed to Professor Sycamore’s lab to say goodbye and met Diantha outside.
• Professor Sycamore asked Chen Shi about the Kalos Three Gods, and Chen Shi agreed to explain them.
• Chen Shi began by naming the Kalos Three Gods as Zygarde, Yveltal, and Xerneas.

Chen Shi told Professor Sycamore what he knew about the Kalos Legendary Pokémon and then traveled with Steven and Cynthia to Kanto. In Viridian Forest, they found a little girl with a Greninja who called Chen Shi “Daddy.”

• Chen Shi led Steven and Cynthia toward Pallet Town after Mew confirmed their location.
• The three heard a child calling for Sweetie and found a little girl standing beside a two-meter-tall Greninja.
• The little girl rushed to Chen Shi and called him Daddy, leaving Chen Shi, Steven, and Cynthia stunned.

• Cynthia grabbed Chen Shi’s ears and twisted them as he pondered Celebi’s warning.

Chen Shi returned to Pallet Town with Cynthia and Steven after Celebi urged him to go to the Sinnoh Region to confront an unknown darkness. They planned to stay at Professor Oak’s laboratory and train, where Gary greeted Chen Shi and teased him about sharing a room with Cynthia.

• On the way to Pallet Town, Cynthia asked Chen Shi about Celebi’s warning, and he admitted he did not know what the darkness was or where in Sinnoh to go.
• Chen Shi said he would train at Professor Oak’s laboratory before traveling to Sinnoh, then invited Cynthia and Steven to stay and train with him.
• Chen Shi, Cynthia, and Steven arrived at the laboratory, where Gary greeted Chen Shi and said he was hungry.
