Professor Kukui has a gift to help Ash get started in the Alola region. It’s an unusual Pokédex that’s inhabited by the Pokémon Rotom—a Rotom Dex!

Team Rocket is just getting started in Alola, too, and their first meeting with a new Pokémon turns frightening when a mysterious Mimikyu draws Meowth into a nightmare. But when they encounter Ash and his classmates, Mimikyu decides to battle on Team Rocket’s side—until an enormous Bewear grabs Jessie and James and carries them off.

Ash is a little disappointed that he couldn’t catch Mimikyu, but he soon sets off in search of more new Pokémon!

At an airport in Alola, a group of passengers get off a plane, including Team Rocket. In a flashback, at Team Rocket HQ, Giovanni is shown bringing up several images of Pokémon found only in Alola as Meowth vows to kick Persian of the boss' lap and take its place. Giovanni instructs the trio to go to Alola and collect Pokémon he hasn't seen before and fulfill the ambitions of Team Rocket. At Professor Kukui's lab, after giving Ash his Pokédex, Professor Kukui connects it to a computer system, which confuses Pikachu as the lights start to flicker. Ash wonders what is going on as Professor Kukui tells him to wait and see as a Rotom appears. Professor Kukui tells Ash they just to wait until Rotom goes inside. As Ash wonders if this means it will go inside the Pokédex, Rotom does just that, leaving Ash curious as his Rotom Pokédex becomes active. After saying hello to the Rotom Pokédex, Ash is surprised that it can talk, as Professor Kukui asks it to provide Ash with all the help it can give. Rotom Pokédex understands and begins to boot up, telling Ash that it is equipped with an assortment of languages to communicate with people. Despite this, it doesn't understand Ash's use of the word "awesome", but Professor Kukui soon explains what it means. Professor Kukui introduces himself and explains that Ash and Pikachu are staying at his place. Rotom Pokédex takes pictures of Pikachu and Rockruff and explains that it is self-learning, which Ash doesn't fully understand. The Pokédex introduces itself as a Pokédex Rotom Version and tells Ash to simply call it 'Rotom Dex'. It begins to call Ash 'User Ash', but Ash says it can just call him 'Ash', as it would be easier. Ash asks Rotom Pokédex to provide information on Pikachu, which it does, and pulls on Pikachu's tail to test it. This results in Pikachu using Thunderbolt which shocks everyone.

In the forest, Bewear is walking about and hears the bushes rustle as a Mimikyu emerges. Bewear looks at Mimikyu before moving on. Litten passes the Pokémon School and watches Komala sleeping before moving on. In the classroom, Ash introduces Rotom Pokédex to his classmates and they introduce themselves. Lillie is amazed to see a Pokédex with a Rotom inside, whilst Sophocles wants to examine its programming, but Rotom Pokédex quickly refuses. As Samson Oak arrives with Professor Kukui, Samson tells Ash that he has quite an interesting item with him, but Rotom Pokédex is confused by Samson's Pokémon impersonations. But Mallow says it is just his way of saying hello, and he likes making Pokémon gags. Rotom Pokédex soon understands and begins making a few jokes of its own. Professor Kukui starts the lesson by saying it will be about field work, and suggests to Ash that now he has his Rotom Pokédex, he should catch a Wild Pokémon, which leaves everyone excited. Professor Kukui says it should be a new challenge for Ash and they all have a Destiny Bond to help him out. The group heads out into the forest.

In the forest, Team Rocket are exploring and plan to catch the first Pokémon they see, but as they left Gourgeist and Inkay back at Team Rocket HQ, it will be down to Meowth and Wobbuffet. Looking around the forest, Jessie finds it creepy as Mimikyu jumps out from behind a bush. They mistake it for Pikachu and are scared when its costume falls down slightly, but Meowth spots it isn't actually a Pikachu. Hearing Mimikyu's voice, it creeps Meowth and Wobbuffet out. James asks what Mimikyu is saying, but he refuses to translate as it is too scary. Jessie says it actually looks kind of cute and decides to catch it, throwing Meowth at it, but his Fury Swipes has no effect. Meowth becomes scared of Mimikyu's talk and orders it to take off its Pikachu get-up. Meowth looks under its rag and promptly faints. Meowth finds itself walking up a long tunnel and wonders where he is before spotting a light in the distance. He goes towards it and sees a Gardevoir, Lopunny and Glaceon which he begins to chase, having fallen in love with them, unaware that they are illusions caused by Gastly, Haunter and a Gengar. Meanwhile, Jessie and James are trying to wake Meowth up. In Meowth's fantasy, the Pokémon all disappear as Jessie and James throw buckets of water on Meowth to wake him up. He thanks them for bringing him back and explains what happened. They all look at Mimikyu and become nervous and run away as nearby bushes rustle as Ash and his classmates arrive.

Team Rocket notices them and their Pokémon and decide to use the opportunity to capture all their Pokémon. They all spot Mimikyu but finding Pikachu makes Mimikyu unhappy. Lillie recognizes it as being a Mimikyu from a book that she read, but Rotom Pokédex interrupts her to provide information. Meowth hears the information about a scholar who looked under a Mimikyu's rag and realizes how lucky he was, as James notices Rotom Pokédex moving by itself. Ash decides to try and catch Mimikyu and has Pikachu use Iron Tail which hits, but Kiawe is surprised that it does no damage. Mimikyu strikes back with Play Rough before attacking with Shadow Claw. Seeing how strong Mimikyu is, Ash orders an Electro Ball which Mimikyu sends back to Pikachu, although Pikachu manages to dodge. Team Rocket are impressed by Mimikyu's strength and Jessie decides to catch it, much to Meowth's horror. As Ash goes to order Pikachu to attack, Team Rocket interrupt and say their new motto, which Rotom Pokédex takes literally. Rotom Pokédex has no data on the super-powerful evil organisation that James says that Team Rocket is, but it is surprised to see a talking Meowth and starts to take pictures of him. None of Ash's classmates have heard of Team Rocket, but Ash explains that they are bad guys. Team Rocket don't know why Ash is in Alola, but they intend to take all of their Pokémon along with Mimikyu. With few Pokémon to use, Meowth goes to battle Pikachu with Fury Swipes as Pikachu attacks with Electro Ball but Mimikyu fires a Shadow Ball to save Meowth from being hit. Jessie realizes that Mimikyu is helping them out, but this isn't the case as Meowth explains that Mimikyu hates Pikachu more than anything else. Jessie allows Mimikyu to attack and it fires another Shadow Ball. Jessie and James are ecstatic about what is going on as Bewear arrives and catches Jessie and James and carries them away. Rotom Pokédex informs Ash of what Bewear is, and Ash remembers encountering it before. Meowth tells Mimikyu to stop Bewear and help save Jessie and James, which Mimikyu reluctantly does, and they chase after them. Ash is disappointed at not catching Mimikyu, but Lillie says there are lots more Pokémon around. Ash and his classmates set off to catch more Pokémon.

Dub edits

  • The Japanese text used in Team Rocket's motto is edited out in the dub.
  • In the Brazilian dub, when Professor Kukui talks about field work, Mallow's line is mistranslated as, "Eu amo fogos de artifício", making the line unrelated to the context.
  • In the Swedish dub, when Meowth is asked to translate what Mimikyu is saying, he says he does not dare to say it out load. In the English dub, Meowth breaks the fourth wall by stating that it's a family show.
