If all this will be confirmed, and I'm pretty sure it will:
- Alolan Raichu is ADORABLE! Never were a fan of the Pika line, but I really love this one. Electric/Psychic isn't the most threatening typing, but it's peculiar and I like it. Surge Surfer is cool, but it'll depends on how much it'll be easy to put terrains on battle. If Tapu Koko will not be OP, seeing them paired could bee awesome.
- I liked Wishiwashi form when first leaked, but now that I see it animated it's freakin' cool! That thing is massive, and looks really menacing! Don't really understand how its ability works, I guess we'll figure it out when it'll be officially announced. Changing form after a certain level sounds as a regular evo, so it must have some differences.
- Pyukumuku, not much to say, it's still really cute in 3D. Having a new, peculiar ability is cool (we're getting TONS this gen), I'm really curious about it. Pure water is quite uninteresting, but maybe the ability or an evo will compensate for it.
- Morelull is cute as hell, reference to real fungi bioluminescence is pretty cool! Hope it'll have also hallucinogenic powers! (I suppose it by its name). Really look like a first stage though.
- Alolan Meowth is still ok, I like it, but I'm actually much more interested in Persian, of course. Retaining Technician could be nice (a special swift with technician Snarl + hidden power?)
- Alolan Marowak retaining Lightning rod is pretty cool, especially considering that it being slimmer will also probably be faster and still immune to electric attacks despite no more Ground type. Everyone is guessing that it'll not be able to abuse the eventual special attack boost, but who said that Alolan Marowak was going to be physical at all? It doesn't have a "thick club" after all, it has spectral flames perfectly suited for a fast, special attacker...
- Guzma & Grunts are ok, but I almost fell in love with that badass punk Plumeria.
