The starter pokémon is the same as its previous version; Snivy, Tepig, and Oshawott. But instead of Professor Juniper greeting you in the beginning, it will be a grown up Bianca. Your other rival from the previous game, Cheren, also makes an appearance as a gym leader. Aside from those two characters, the previous game's champion Alder, and the antagonist N will be making appearances as well.
There are other new features, too:
This is a new mini-game where you direct a film, picking your lines and settings to create an your very own original movie. You can choose your Pokémon for the cast and have your monster star the film, too.
-Pokémon World Tournament
The World Tournament facility will let you fight against gym leaders and champions from previous versions of Pokémon. The player can decide for it to be either a single or a double battle, and using your Wi-Fi connection you can fight against other special trainers as well.
No word whether your Poké actors will trash their trailers and enter rehab. Knowing Nintendo, they won't.
