The Pokémon Co. officially announced the next generation of the Pokémon anime series in Japan on Sunday and released the first trailer for the upcoming series.

The teaser trailer confirms leaked material for the new series that popped up online days earlier and showed Ash returning, along with Pikachu, and a brand-new character joining the show. It aired after the latest episode in Japan

The new Pokémon anime trailer reveals the name of the new character, a boy named Go (or Gou in Japanese), and his partner Pokémon, Scorbunny.

So far, not much is known about Go, but according to the website Serebii, he is "a young boy just starting out on his journey. His goal is to catch all Pokémon and eventually find the Mythical Pokémon, Mew who he saw when he was a child."

Daiki Yamashita is Go's Japanese voice actor. Fans may recognize him as the voice of Izuku Midoriya in the My Hero Academia anime.

Pokémon Scorbunny is one of the three starters of the Galar region, the setting of the upcoming Sword and Shield games, which means that Go is from the Galar region.

From the looks of the poster and trailer, the next series in the Pokémon anime won't stay in the Galar region but instead have Go and Ash travel to other regions in the Pokémon world. It's unclear how the Pokémon Co. plans to tackle this, but it'll mark the first time the series explored the world on this scale.

The new Pokémon series will begin November 17, after the conclusion of the Sun and Moon anime in Japan. The dub of the anime is about 20 episodes behind, so the English series won't air until the beginning of 2020.

Sunday's episode began the battle between Ash and Kakui. The official Pokémon YouTube channel uploaded a preview of the next episode, which you can watch below.

The Sword and Shield games are set to release in November with a region full of new Pokémon, Galarian forms of older-generation Pokémon and new battle mechanics.

Pokémon: Sword and Shield will be released November 15 on Nintendo Switch.

Pokémon was created by Satoshi Tajiri and Ken Sugimori and has gone on to become massively popular around the world. The games were first released in 1996, and a movie, Detective Pikachu, came out earlier this year.
