Not particularly fond of them, to be honest. They don't serve much of a purpose beyond appeal, and only a few of them are actually worth using in a playthrough imo. The fact that Dedenne's Scarlet dex entry states that its electricity-generating organ is "not fully developed" yet it can't even evolve into anything makes me wonder why these things exist beyond adding just that microscopic bit of flavor to a generation. If most/all of them were like Raichu and Pawmot in terms of power or Morpeko in terms of uniqueness, I'd forgive them a little more. But as it stands, most of these Pokémon are filler at most to me.
oh yeah i guess that makes se jun parks vgc 2014 accomplishments even cooler but iunno itd be cool if pachirisu wasnt awful beyond its specific niche
