So what are the chances that the post-game involves coming across Lillie (and Gladeon? I don't remember if he went with her), at which point the Alolan forms become available?
Alolan Raichu isn't a new evolution. It's an alternate Raichu that takes the same spot / number in the Pokédex.Wait, Aloan Raichu is in the game, but other new evolutions for Kanto pokemon aren't?
