The fact that Moon has an Alolan Grimer so early suggests to me that we won't be getting a repeat of X having mostly Mega Pokemon and Y only getting one.
Though I honestly do expect more than what we have.
So for Sun:
Alolan Persian (I honestly wouldn't be surprised if Dollar never evolves. If only because Alolan Persian looks really weird and Nanu has one.)
Incineroar
Passimian
Kommo-o
Alolan Sandslash
Solgaleo
Moon:
Decidueye
Alolan Muk
Toxapex
Vikavolt (I honestly didn't expect anyone to get a Pokemon that had a evolution that was a Totem.)
Alolan Ninetales
Nihilego (Because Poison-type and we need at least one Ultra Beast on a Dex holder's team.
I'd like to see him with a final team of:
* Alolan Persian
* Incineroar
* Bewear
* Togedemaru
* Mudsdale
* One of the Ultra Beasts maybe? Or another Alolan Form, like Exeggutor
I can't see Mudsdale, honestly. He already has the Gallop function on the Rider Pager, so he can just summon a Mudsdale whenever he wants.
Plus it's Hapu's main Pokemon, and it'd be kind of redundant when she appears. I guess Bewear is kind of out since it seems to be Hala's main Pokemon here instead of Crabominable. ...Though I guess that means Crabrawler's free now.
As for Moon:
* Decidueye
* Vikavolt
* Toxapex
* Alolan Muk
* Salazzle
* Minior or an Ultra Beast (Nihilego...)
And as stated above, Salazzle is Plumeria's main force. (Though, I actually was expecting Plumeria to use Mareanie here. But it's a Dex holder Pokemon, so surprise surprise.)
