Just a few days after the leak of the new Mega Evolutions for Pokemon X and Y, an official trailer has debuted that highlights all of the new Pokemon and some new evolutions.

First up are the evolved forms Chespin, Fennekin and Froakie. Respectively, they turn into Quilladin, Braixen and Frogadier.

Next on the list of newly-debuted Pokemon are a few critters that have been restored from fossils. One of them is a little T-Rex-like Pokemon called a Tyrunt and the other is a Brontosaurus-like Amaura.

Before getting on to more Pokemon reveals, the video shows us that you can change your trainer's outfit in order to customize your own style and show off to the world. Who said the world of Pokemon couldn't be fashionable?

Speaking of fashion, the Furfrou Pokemon is revealed and can be groomed to have different looks, including ones with heart and star motifs. The male and female forms of Meowstic are also revealed, giving us a look at their dimorphism.

Last but not least are the new Mega Evolutions. As mentioned in the leak of the CoroCoro magazine scans, Mega Garchomp will appear in X and Y. And, perhaps most excitingly, we're shown the two Mega forms of Mewtwo: Mega Mewtwo X and Mega Mewtwo Y. As you could assume from their names, each Mega evolution will be exclusive to either Pokemon X or Pokemon Y.

Look out for all of these exciting new Pokemon and features when the game comes out on Oct. 12 for the Nintendo 3DS.
