Did you really just go there?
A “cartoon”?
Cartoons are for kids. Things like Barney and Teletubbies. And don’t try to tell me that Western cartoons can be made for adults. Ugly / edgy “adult” animation like Sausage Party are crude and tacky.
Pokémon (ポケットモンスター) is an anime (アニメ). Anime (Japanese for immersive visual storytelling) has better art, better writing, better plots, and is MUCH more complicated.
Some anime is clearly mature and only intended for adults. For example, Gantz has too much blood for children (cf. Lion King), and Boku no Pico has too much nudity. These things can only be appreciated by the adult mind.
So, on topic, Pokémon is not a cartoon and is not cartoony
