I thought it was stated that they share a secret with Rockruff (like when Rockruff was first revealed or something)? If this is Rockruff's secret, then it wouldn't be impossible to imagine something similar for the starters.
Yes this is what Iwas talking about. Recently people think that by looking at the scan, that's a mistranslation on it. Therefore the starters could very well have alternate forms ( And I still find this likely), but it's not a guarantee as the translation is 100% clear on if the secrets share or separate.
Actually I don't think that the day and night thing was a mistranslation either. The official site says that Rockruff evolves to it's forms depending on whether the Sun or the Moon is influencing it. It sounds like the power of the Solgaleo is so great that even if it's night Rockruff still evolves into Midday form in Sun at night. Likewise for Rockruff Midnight forme with Lunala, even during the day. I can see it being able to evolve depending on the time of day in future versions, but for SM it depends on the mascot.
True it probably was, just badly stated. Therefore it would still lead to a big misunderstanding in translation. But with the recent trailer, we got things sorted out which was nice.
Should point out that one of the big four (three now I think) leaks claims Alolan Butterfree, but in the most recent trailer we see a regular Butterfree
This is certainly worth considering, but so far each leak ( I believe)has an Alolan form that has been seen with it's regular appearance in the game. Which means one of three things:
1)They are misinformed on what got a form and what didn't.
2) Their knowledge of the forms comes from earl versions of the game in which maybe these had drafts for forms, but they never got implemented. Like Mega Flygon in ORAS.
3) The non forms were thrown in there so no one would be suspicious of them.
I'd say 1 is likeliest, but we could also somehow have regular forms and Alolan forms. As each trailer says, footage is not final. Perhaps they threw in pokemon they like for testing purposes, even if they had Alolan forms. I'd say this is also possible, as we've seen that they've created double battles on routes with the female character. Thus showing these battles are just to show the game off and nothing more.
So it is still possible they could get forms, but we shouldn't think they are 100% guaranteed.
