Our heroes are geared up for some serious stargazing—Alexa has told them about the Conley Comet, which is scheduled to make a rare appearance tonight! She’s excited to film this celestial event, including the Pokémon who always gather on the mountaintop to watch the comet approach.

Ash, Iris, and Cilan want to know more, so Alexa shows them the whole story in an old book. In ancient times, a Trainer named Conley calmed down a group of attacking Pokémon and befriended them, saving the island and becoming a hero in the process. The islanders built an impressive battlefield on the mountaintop in his honor, and as Ash and friends make plans to see it, they are approached by a mysterious woman wearing a crown. She confirms that they’re going up the mountain, then gives Ash a medal and tells him it will be useful.

Meanwhile, Jessie, James, and Meowth are disguising themselves as some of the Ghost-type Pokémon who live in the area, intending to follow our heroes and steal Pikachu!

Inside the ruins of the battlefield, Ash and the others discover a huge statue of Conley—but are quickly distracted by the disguised Team Rocket popping out of hiding to scare them! Alexa’s Helioptile, who’s been nervous throughout the trip, reacts with a massive surge of electricity. James gets zapped and stumbles into the statue, causing it to topple over and land on Jessie, who angrily throws it aside. The three villains discard their disguises—only to find themselves floating in midair. Several Gengar and Banette appear from within the ruins, using Psychic to keep Team Rocket away from the statue. When the angry Pokémon descend on Ash and the others, Alexa brings out her Noivern (an impressive Pokémon from the Kalos region) to battle them, giving everyone a chance to escape!

The Ghost-type Pokémon aren’t giving up that easily, though, and the chase continues until a Shadow Ball knocks Ash off his feet. The medal he got from the mysterious woman falls out of his pocket, and the Pokémon are immediately interested. Meowth listens in so he can translate: it turns out the medal actually belonged to Conley, which marks Ash and the others as friends rather than enemies. Cilan figures out that these Pokémon are the very ones Conley once befriended! And after the statue of Conley is restored to its rightful place, the Ghost-type Pokémon are very happy. (Of course, Team Rocket can’t leave it there, and they try to take Pikachu even after our heroes helped them get away...but the Pokémon quickly send them blasting off again.)

Night has fallen, and the blindingly bright and beautiful Conley Comet finally makes its appearance! The Ghost-type Pokémon begin a joyful dance, and the mysterious woman who gave Ash the medal reappears from the ruins. She explains that the Pokémon are dancing to celebrate their ancient hero, and identifies herself only as “the one who knows the past and then passes it on to the future.” Alexa starts filming as Ash, Iris, and Cilan join the celebration as well!

The next morning, Alexa tries to play back her recording, only to discover that it’s nothing but static. Ash’s medal has disappeared, too. Alexa remembers that the medal looked familiar, and flips through her book to look it up. And she finds it—along with an old picture of the mysterious woman standing next to Conley! Could the woman have come to them from the distant past?
