"A misconception people have about Alola Forms."

They help Pokemon adapt to the region, either by fending off predators, such as Marowak scorching any Grass type Pokemon that would've preyed on it in the past or the variation is a product of them unleashing some hidden power they held within, like Exeggutor getting increased exposure to sunlight in the tropical climate which helped it grow.They can't give Alolan Forms to Pokemon that would have no problem if introduced into the region, like Mantine and Octillery because their dietary cycle wouldn't be disturbed.I agree, it is possible that others may have had the potential to receive variants, like Tropius farming an exotic fruit so that may be disappointing. via /r/pokemon http://ift.tt/2wISLWn
