>>54294586>And is Pikachu even that prominent in the other games?Pikachu is very prominent. There's not a game where he doesn't at least make an appearance, he's even a starter option in many of them(or Pichu in some Pokemon Ranger's, but close enough).
He also gets an appearance in a shit ton of spinoff animations as well. Even if he's not a character in the story itself, they'll throw a pikachu in somewhere.

Pikachu IS Pokemon. Not some dumb human that doesn't appear outside of his dumb show.
