This was really enjoyable. It's not often that so-called 'filler' pokémon are given so much personallity, and good personallities at that, so this is something I'm going to savour.
Even if it was a slight re-tread of Muk, Grimer was undoubtedly the funniest, especially when it slimmed itself down and copied Hikari's pose to the point where you could slap on a illegally short mini-skirt and not tell the difference between the two.
Oh that Hikari, and her bulging, sludge secreting pores.
Honestly, various people are always going on about how the characters should only receive pokémon that 'fit them', but the Hikari-Grimer pair is just one, big middle finglonger. If Grimer wasn't a first generation rental pokémon part of a story driven arc, I'd be speculating like an average Serebii Pokémon Animé section member without a sliver of imagination right about now.
"Haven't you ever heard of 'ladies first', you chauvinistic shonen hero!"
"NO WAI, YURA GURL!?!"
Wa-wa-waaaaaa.
Even though it's only been one episode thus far, I'd be up for Aoi returning in the future as a full-time rival to Ash. She certainly did a good job of filling that role here, and her constant spats and parallels with him were quite fun to watch. And from what I can gather, it's going to be an ongoing thing for the next couple of episodes, so there's some cause for celebration.
Shinjo's interpretation of Moukazaru looked really cool, despite how many of you were pegging it as 'hideous' in the preview. That'll teach you to judge a pokémon by a single frame.
