A newly released trailer for the Sun and Moon games has finally revealed the evolved forms for the seventh generations Starter Pokemon, along with a bunch of other new features. Take a look.
The fact that Mega Evolutions are going to be making a comeback in Sun and Moon is something of a relief where my Mega Factor series of posts is concerned. Of course whether or not there will be any new Mega Evolutions showing up in Sun and Moon remains to be seen.
As a side note, the Pokedex information on Brionne has it classified as the Pop Star Pokemon. I really have to wonder what Brionne's evolved form is going to look like.
