Starters possibly have multiple formes, I didn't believe it at first but I do now, here's why

Pokemon moon takes place with night being the day time (hard to put into words). Now, in the Chinese leak, he mentioned that rockruff evolved into a werewolf Pokemon. This is associated with the moon. Now, the leaker also revealed that the leaked starter evolutions were real. Now all 4 of these things are likely real. Don't forget that rockruff and the staters share a secret and I'm beggining to think that it's version exclusive evolutions and that the leaked starters we've seen are the "moon" versions. Similarly, werewolf rockruff evo is also it's "moon" version.

But, if the Chinese leaker knew everything about the games, why didn't he say that? I think that he only played through Pokemon moon, and not sun, so he only experienced the moon versions of rockruff and the starters, it's very possible they could all have different forms as their secret.
