It was previously revealed that the new Pokémon anime will follow an original storyline.

Pokémon is a Japanese anime television series, part of The Pokémon Company’s Pokémon media franchise, which premiered on TV Tokyo in April 1997.

The anime franchise consists of seven sequential series in Japan, each based on a main installment of the Pokémon video game series. In the international broadcasts, these series are split across 25 seasons, with the 25th season, Ultimate Journeys.

The Pokémon anime series was largely credited for allowing anime to become more popular and familiar around the world, especially in the United States, where many Pokémon films are among the highest-grossing anime films. It is also considered to be one of the first anime series on television to reach this level of mainstream success with Western audiences, as well as being credited with allowing the game series to reach such a degree of popularity and vice versa. Pokémon is regarded as the most successful video game adaptation of all time.
