>>54095773The best feeling on a first playthrough of a new generation is reaching the champion and having them totally blindside you with something that you've never seen before; Alder's Volcarona and Wallace's Milotic both do good jobs of that since it's very unlikely you would have one of those mons for yourself on an initial playthrough since Feebas is so absurdly rare + nearly impossible to evolve by chance, and you'd only have Volcarona if you hatched the random egg a single random NPC can give you and carried it to an absurdly high level.
While not being their ace, Spiritomb also has the same effect on Cynthia's team and I think it contributes to the collective opinion of her fight being so challenging, since she leads her team with something you have almost certainly not faced before (and has no type weaknesses either so you can't even begin to work out what type it is or what you should lead against it).
