People want Giovanni or Gary to be Ash's final "boss" battle of the series... but does anyone else think it would be kinda cool if his last fight in the series was against Professor Oak? It would be a fun little nod to a cut battle from the gen 1 games, a heck of a plot twist if Oak was actually a former champion of sorts or belonged to some super secret elite group of trainers, and it would be a meaningful battle since Oak has been a part of Ash's life since the beginning. I know some people will hate the idea since it sounds like a cringy fan fic idea, but Idk, maybe it could be a fun and surprisingly way to close out Ash's story.
