>>55360716They start resetting Ash in Gen 5 onward for every series there of. Literally worse than assassinating the character.
Gen 1 to 2 to 3 to 4 he follows a steady progression of getting better and learning from his encounters while still being the same at the core.
Gen 5 they just made him a rookie and had amnesia so he was breaindead, forgetting stuff like which Pokemon is effective against which types. And his Pikachu gets one shotted by a lv5 starter at the very start.
XY is the opposite, he is suddenly this generic shonen stock brooding self insert NPC.
SM is another extreme and now he is this hyperactive imbecile meme character.
JN he is suddenly deaged 5 years and now has insane levels of plot armor and starts one shotting everyone cuz it was his send off season.
