>>28425917Actually I just checked out the rest of the exclusives to do some quick comparisons. There were 6 families exclusive to either version.
Of those, Magmar/Electabuzz got baby and evolved forms in later generations. Pinsir got a Mega, Scyther has an evo from Gen II.
Vileplume has a split evo in Gen II, but I don't think that rules it out completely. Its counterpart, Victreebel, has no alt forms or evolutions.
3 remaining families in Blue (jap Green) have Alolan forms: Sandshrew, Vulpix, Meowth (Persian unrevealed, but no reason to doubt its existence)
None of the remaining Red exclusives (Ekans, Mankey, Growlithe) have confirmed Alolan forms.
This casts further doubt on Ekans getting an Alolan form and the legitimacy of this rumor, but increases my idle hopes of Bellsprout getting one.
