Pokémon is one of the most significant anime of all time. Beginning in 1997, the series quickly found worldwide popularity.

The original series finished airing, but it undoubtedly established the foundations for the popular franchises before ending.

In Pokemon Horizons, there was a need to make the new Pikachu feel distinct as a character. At the same time, the creative team needed to make sure that he wasn't completely different from Ash's.
