>>55086591>Nah there's no reason to have him go back and beat everyoneYes there is , specially if they has unsettled score with them.
Truth is, Ash using his reserves to beat many past trainer makes a better series than Horizon. In fact Ash's Seismitoad using Earth Power to defeat Alain's Mega Charizard X without any Gimmick would be a well earned karma since Earth Power and Blast Burn has similar animation.
>We already know he'll beat them since he's the world champion now and the strongest.No we don't since Misty defeated him which means he can lose based on which Pokémon he use against them.
>There's nothing left for himAgain wrong as SV and its DLC has given so many things for Ash to do unlike Liko and Roy who has nothing to do at all.
