Ribombee - holy Arceus this is ADORABLE! Heck, they probably could've called it "Adorabee" because of how flippin' CUTE it is! It almost reminds me of a kwami from the Miraculous series. Well now I know who to call for aid when Alola needs a superhero. XD
Steenee - well, I never could've imagined that our delicious little Bounsweet would hatch like an egg into a little fruit girl. Point to Game Freak for originality, I guess. Anyway, keeping this Pokémon around is said to be a handful - like raising a teenager. And apparently it can kick like a Hitmonlee, so avoid those dainty legs like the plague.
Tsareena - hoo boy. It seems to be tradition nowadays for there to be a "pretty girl" Pokémon in each generation, and looks like Tsareena is the reigning princess for Alola. It's funny that it happens to be a fruit this time, because I can already joke about how "delicious" she is.
(Can't wait to see the fanart of this one...)
Hakamo-o - really cool-looking Pokémon here. It looks like something out of Aztec mythology, you know?
Kommo-o - It's a freaking Struthiomimus with samurai armor! Design aside, I really like this guy's flavor text of it being a silent guardian over all the little Jangmo-o (probably thinking back to its own childhood as it does so). I can't wait to see how this bad boy holds up in battle. I'm going to name mine Ozzy - or maybe Brachydios, because look at dem arms.
Silvally - no offense, Arceus Junior, but I can't take that name of yours seriously. Aside from that, this unmasked chimaera is an absolute badass in terms of design, just like it's "pre-evolution". I don't know how you can call this an evolution when all that happens is Type: Null taking off its helmet, but oh well. The backstory for this Pokémon is really impressive, and its ability to change its type is damn great.
Alolan Muk - it looks like a four-year old's art project come to life. In all seriousness, though, this Alolan form looks pretty cool. Not gonna lie, this guy is legitimately intimidating despite those flashy colors.
