If you (the player) has recently just moved to Alola from Kanto, then you know all the first 151 pokémon from there, so when you encounter them and they have changed, they are different forms of the pokémon you knew back in Kanto. However, due to living in Kanto you wouldn't know any of the other pokémon from the following regions so you would mentally assume that they were all of their form when in Alola, so an Alola form for these mons isn't possible for the trainer to know, as they don't know what they looked like initially
I'm okay with this

Lamest excuse ever.
The game is built for all fans not for some one faggot that moved from Kanto (which by the way is another fan theory)
>>27822276
But a lot of gen 2 pokemon live in kanto (houndour, slugma.....)
>>27822339
It isn't a fan theory dumbass, you actually moved from Kanto to Alola - have you even paid attention to the story thus far
>>27822361
Are you retarded?
>>27822361
You moved from anorther region... Not necessarily Kanto
Or post source
>>27822276
what if post game you go to Kanto and then there's Kanto versions of Alolan pokemans
like a ice type sandcastle

I'll kill myself.
I'm suicidal anyway, so that's not anything special though.
