Unlike Pokémon Black & White, Black 2 & White 2 feature a Pokédex that contains Pokémon from various other regions of the game dotted around all the areas of Unova, with the dex having 300 Pokémon within it before the National Pokédex is obtained, making it the biggest regional Pokédex.

There are various other new areas in Unova, with their own new Gyms and Gym Leaders. The game begins in a previously inaccessible part of Unova to the southwest as you take control of a character who lives in Aspertia City, with their childhood rival. Pokémon Black 2 & White 2 are set within the Unova region 2 years after the events of Pokémon Black and Pokémon White, and as such, a lot has changed in the region. These games feature Kyurem's alternate forms within them Black Kyurem in Black 2 and White Kyurem in White 2.

Pokémon Black 2 & Pokémon White 2, otherwise known as Pokémon Black Version 2 and Pokémon White Version 2 are the second set of games of the long anticipated fifth generation of Pokémon.
