Pokemon Black and White 2 isn’t just going to have new forms to existing legendaries.
Black and White 2 takes place two years after the events of the first Black and White games. While it’ll take place in the Unova region once again with the current Pokedex which numbers at 649, the similarities end there. Not only does it feature new heroes, rivals, and even new gym leaders, the trailer also shows that something major has happened to Unova as the entire right half of the land has been frozen over. It probably has something to do with the fact that the legendary Kyurem is an ice-type and has two new forms which seem to absorb the other two legendaries, Zekrom and Reshiram.
The trailer also teases Pokemon‘s next movie. Not a big deal to those who are just fans of the game and not necessarily the franchise but like a lot of Pokemon‘s movies, it teases the digital distribution of a Pokemon not yet available in the current Pokedex. In this case, it’s the unreleased Keldeo of Black and White‘s musketeer trio.
