Pokémon Season 20 Episode 42

Ash’s Pokémon School class is taking a field trip to the Kanto region! Principal Oak is excited to visit his famous cousin in Pallet Town, and Professor Kukui says some special guests will be joining them. When those guests turn out to be Brock and Misty, Ash is delighted! Everyone marvels at the many Pokémon living at Professor Oak’s lab, and Brock offers a demonstration of the difference between Kanto Pokémon and their Alolan counterparts. Of course, Team Rocket is up to their old tricks, but the “original Twerp trio” quickly sends them blasting off again. Tomorrow, Misty has big plans for everyone: a battle at her own Cerulean Gym!
