What are the writers' own thoughts on all Ash's current/former official Trained Pokémon?

What's happening with you guys? From Butterfree to Dracovish, I'm just wanting to know what you think are any of the Japanese anime writers' thoughts on all of Ash's current and former official trained Pokémon and all their previous unevolved/middle-evolved forms that they had evolved from already, you know, even including by their fitness for his party, bond and rotation for various reason? However, these do not include Ash's Pikachu for his Pokémon that he has right now on hand, but no, sir, not even a Gentleman's Raticate or Sabrina's Haunter for his temporarily owned Pokémon, and not even any of their former devolved or reverted egg states from the Journeys anime episode, Showdown at the Gates of Warp!, either, okay? Thanks.😉
