"The Evil Nyarth is an Alolan Nyarth!?"
After Musashi eats an ice cream that Nyarth was saving for himself, he becomes so angry that he runs away and (not looking where he's going) falls into a muddy swamp, where he meets an Alolan Nyarth. Musashi and Kojiro, searching for Nyarth, mistake the Alolan Nyarth for their Nyarth and take it back to their base. The newcomer starts ingratiating itself with the other Rocket-Dan members, although it's obvious to Nyarth that the Alolan Nyarth is trying to take his place in Rocket-Dan. At the Pokémon School, a lesson on teamwork is interrupted when Nyarth kidnaps Mokuroh and delivers him to the Alolan Nyarth. However, the Alolan Nyarth has a hidden plan and actually succeeds in capturing Pikachu. Mokuroh leads the gang to Rocket-Dan and a battle begins, but Mimikkyu's hatred for Pikachu causes it to accidentally release Pikachu, the Alolan Nyarth deliberately flees from the battle, and Satoshi's "Sparking Gigavolt" sends Rocket-Dan flying. Later, Rocket-Dan is shocked to find that the Alolan Nyarth has arrived at Rocket-Dan Headquarters, ingratiated itself with their boss and has more nefarious and self-serving plans up its sleeve.
