• The immediate crisis ended, leaving the group to face the consequences of the operation.

Substitute Entei fought the out-of-control Number 66 while Yan Yang and Iku confronted Moke and the Trainers over the Aether Foundation’s experiments. Moke tried to win the Trainers back by offering them Number 77, leaving them to decide whether to side with him.

After six more UB01 emerged and Moke sealed the battlefield, Yan Yang and the others fought to survive until dawn. With the Pokémon overwhelmed, Yan Yang overextended his Evergreen Power to strengthen Number 77 and Armorouge, who prepared to reveal his hidden power.

• Armorouge decided to stop hiding his strength and roared, drawing everyone's attention as he prepared to test his hidden power.

Armorouge awakened an overwhelming Overlord Domain and revealed that Yan Yang’s trust in him had unlocked the Soaring Cape’s ability to let him fly. Strengthened by Armorouge’s domain, Yan Yang and Iku’s Pokémon defeated the Ultra Beasts, while Azure became even more obsessed with capturing Armorouge.

• Substitute Entei pinned Number 66, but its self-destruct program began a countdown.
• Substitute Entei carried Number 66 outside and ran two hundred meters away from the building before collapsing.
• Number 66 exploded, destroying itself and killing Substitute Entei in the blast.
• Entei, Litleo, and Master Hu saw the explosion from their speedboat, and Entei's wooden carving broke.
• Master Hu used his Psychic Power to confirm Yan Yang was safe and restore the carving, while Entei told Litleo not to mention that it had broken.

Wang Ba freed Moke by taking control of the Trainers’ Pokémon, leaving Yan Yang’s group surrounded and outnumbered. Just as the Aether Foundation prepared to capture them, Entei broke through the barrier, and Yan Yang ran to greet it as a close friend.

• Wang Ba explained that the Pokémon had eaten something he gave them, then refused to help Moke capture Armorouge and the others.
• Wang Ba sensed a powerful Legendary Pokémon approaching and left, while Moke ordered his people to capture Yan Yang and Armorouge.
• Entei roared and melted the barrier with a burst of flame, and Yan Yang tossed Cosmog to Iku before running to hug Entei’s leg.

Number 77 escaped control after killing Azure, found mysterious discs and rescued Rockruff and Skrelp, who had found a stone slab. Yan Yang spoke with Armorouge while Entei concealed that his conscious Substitute had died in the explosion.

• Number 77 discovered the explosion caused by Number 66 and followed a strange signal to a room containing a box of discs.

• Number 77 refused to carry the two Pokémon but slowed down as they followed him with the slab.
• Yan Yang apologized to Professor Iku for hiding his situation, and Armorouge asked to speak with him privately.
• Entei realized Yan Yang did not know his conscious Substitute had died in the explosion and decided to keep the news from him.

Yan Yang reassured Armorouge after it confessed to having killed someone, and the two openly affirmed their affection before returning to the others. The group prepared to leave, but Armorouge’s Poké Ball was sent to Iku’s laboratory because Yan Yang had exceeded his Pokémon carrying limit, and Yan Yang sensed someone familiar might be in the blast ruins.

• Armorouge confessed to Yan Yang that it had killed someone and feared he would reject it, but Yan Yang comforted it and accepted its affection.
• Armorouge hugged and kissed Yan Yang, then carried him back to Entei, where Number 77, Rockruff, Skrelp, and Houndoom had gathered.
• Yan Yang recognized the Rock Plate Rockruff had found, praised her, and learned from Iku that the League would arrive to handle the aftermath.
• Yan Yang captured Armorouge, but Iku explained that its Poké Ball had been sent to his laboratory because Yan Yang had exceeded his carrying limit.
• The group left the area and saw the crater from the explosion; Yan Yang wondered if someone familiar had been caught in it.

Yan Yang and the others reached the shore and boarded Master Hu’s ship, where they watched an unusually brilliant sunrise. Cosmog’s light empowered Rockruff, who evolved into a Lycanroc unlike any form Yan Yang recognized.

• Master Hu explained that he had brought Yan Yang’s group from Johto to Alola by ship, and they boarded the crowded vessel.
• Yan Yang held the exhausted Cosmog while Rockruff perched on his head, and Master Hu kept the seasick Yan Bao confined in a shaking Poké Ball.
• Yan Yang and Iku watched a dazzling golden sunrise over the sea, and Rockruff sensed a force stirring within her.
• Cosmog glowed and released dark-blue energy that gathered around Rockruff, giving her the strength to evolve.
• Rockruff evolved into a bipedal Lycanroc with golden eyes and howled as the sun rose.

Yan Yang discovered that Rockruff had evolved into a previously unknown Dawn Form Lycanroc, while Cosmog’s worsening energy deficiency temporarily stabilized at the cost of making him weaker. After Yan Yang collapsed from exhaustion, Celebi appeared at the ruins and considered a final way to save the destroyed Substitute Entei.

• Yan Yang used God's Eye to identify his newly evolved Lycanroc as a level 25 Dawn Form with the Rock and Ghost types and Shadow Tag ability.
• Iku's Lycanroc emerged from her Poké Ball, and Yan Yang's Lycanroc respectfully greeted the older Pokémon.
• Yan Yang learned that Cosmog's internal forces had united temporarily, but Cosmog remained weak and needed Konpeito to regain some vitality.
• Master Hu warned Yan Yang not to transfer Evergreen Power into Cosmog, and Entei reassured Yan Yang that Cosmog's parents might be able to help.
• Yan Yang became too exhausted to stand, so Entei placed him on his back with Psychic Power to let him sleep.
• Celebi returned to the ruins, saw the destroyed Substitute Entei, and decided to pursue a rule-compliant way to turn him into a true life-form.

Yan Yang dreamed of Arceus, who encouraged him to find the remaining Plates and reminded him to keep loving Pokémon and their world. He woke on Entei’s back in a cave, where Entei had brought him for a day alone together, and they set off for a run as Entei vowed to confront Raikou for frightening him.

• Yan Yang mentioned that Raikou had once run so fast that he nearly frightened him, prompting Entei to promise to teach Raikou a lesson.

Yan Yang spent a day riding Entei across the island, then shared the sunset with him on a mountain summit. They reaffirmed their affection for each other, exchanged kisses, and ended the day watching the sun disappear.

• Entei carried Yan Yang through the forest, across grasslands and along the coast before taking him up a mountain.

Yan Yang spent the night with Entei, explaining how he had reached Alola and recounting the Pokémon and people he had met there. Entei comforted him over the missing Substitute while hiding that the Substitute had died.

• Entei asked Yan Yang why he had suddenly appeared in Alola, and Yan Yang explained the random teleportation side effect, his tablets, and the Phantom Crystal.
• Yan Yang reassured Entei that his abilities were worth their drawbacks, and Entei promised to stay by his side and protect him.
• Yan Yang told Entei about Lycanroc, Cosmog, Number 77, and Armorouge, and Entei worried about the dangers some of them might bring.
• Yan Yang described the kind people he had met, including Dr. Iku, then grew sad when Entei asked why the Substitute had left.
• Entei told Yan Yang to respect the Substitute’s choice and falsely assured him that the wooden carving proved the Substitute was alive; Yan Yang fell asleep against Entei’s belly.

Entei secretly gave the sleeping Yan Yang a flame blessing that strengthened his body and gave him an affinity for fire, while reflecting on Yan Yang’s future as the Brave of the Rainbow. Entei decided to discuss that responsibility with Yan Yang after they returned to Johto and resolved to watch over him.

• Entei infused Yan Yang with Flame's Blessing while he slept, and Yan Yang absorbed the power without resisting it.
• Entei considered how the blessing could improve Yan Yang’s constitution, reduce fire damage, and eventually let him wield fire.
• Entei worried that Yan Yang would one day die long before him and felt helpless about their difference in lifespan.
• Entei judged Yan Yang the strongest candidate to become the Brave of the Rainbow but worried he was too young to face Ho-Oh’s challenge.
• Entei decided to ask Yan Yang what he wanted after they returned to Johto and kept the blessing secret so Yan Yang would not recklessly test it.

Yan Yang woke in Entei’s embrace and challenged him to their usual race back to the research institute. Entei’s newly granted blessing briefly boosted Yan Yang’s stamina and speed, but Entei caught him and carried him the rest of the way, unaware that their heartbeats had briefly resonated.

• Entei caught Yan Yang before he reached the institute, and Yan Yang’s sudden boost faded as he was tackled.
• Entei carried Yan Yang on his back, and their heartbeats briefly resonated while neither noticed.

At the research institute, Litleo sulked over Lycanroc evolving before him while she tenderly cared for Cosmog. Number 77 weighed whether he could learn to care for Yan Yang, Armorouge agreed to follow and protect him, and the Pokémon awaited Yan Yang’s return.

• Litleo blamed Master Hu for costing him the chance to be the first Pokémon Yan Yang saw evolve, and Master Hu threatened to keep him in a Poké Ball.

• Number 77 considered the faintly resonating box, feared being experimented on again, and reluctantly decided he would try to like Yan Yang without approaching him first.
• Armorouge accepted that he would follow and protect Yan Yang, and he gave Skrelp his blessing to pursue what she wanted despite their likely separation.
• Entei returned with Yan Yang, drawing the waiting Pokémon’s attention.

Yan Yang returned to the institute and reunited with his Pokémon, where Litleo unexpectedly evolved into Pyroar. He welcomed Skrelp and Number 77 into his adventure group, while Number 77 secretly planned to leave once he had broken his mask.

• Litleo's Everstone shattered as he charged at Yan Yang, and he evolved into Pyroar before tackling his Trainer in greeting.
