As of the end of The Rainbow and the Pokémon Master!, the To Be a Pokémon Master sub-season finale, I knew that some of Ash's current and former officially Trained and/or Bonded Pokémon that didn't physically appear in the To Be a Pokémon Master sub-season included: Butterfree Primeape Noctowl Larvitar Torkoal Ambipom Gliscor Gible Greninja (even though it appeared only in a flashback as a Frogadier) Goodra (even though it appeared only in a flashback as a Goomy) Lycanroc Nebby, nickname of Solgaleo Naganadel Melmetal Lucario (even though it appeared only in a group photo) Dracovish (even though it appeared only in a group photo) Now I wonder why you think some of Ash's Pokémon didn't physically appear in the To Be a Pokémon Master sub-season as of the end of its finale?
Well I mean Butterfree like a long time ago went to go be with a female Butterfree and do what Buterfrees did best. I haven't seen him since then so if I missed him my bad. But I mean Butterfree went to live his best life. Lots of the others though are so many questions. So this is interesting to think about
