Japanese magazine Telubi-kun recently revealed a special part of the Pokémon the Series: Sun & Moon anime. During two episodes – titled Kanto in Alola! Brock and Misty!! and Gym Battle! Z-Moves vs Mega Evolution!! – on September 14 and September 21, respectively, Ash and Pikachu briefly return to the Kanto region for a school project. Ash gets to pay a visit to his old Pokémon and is able to meet up with his original traveling companions – Brock and Misty – and battles them once more.
Brock’s main Pokémon appears to be Mega Steelix while Misty is partnered up with a powerful Mega Gyarados.
