Pokémon Black/White Version 2 — the events take place two years after the events of Pokémon Black and White. During this period, many changes occurred in Unova: new locations are available in the southwest and northeast of the region, and some pre-existing locations cannot be visited or have limited access until later in the game. Three new Gym Leaders and a new Champion are introduced, and the Unova Pokédex is expanded to include Pokémon foreign to the region, similar to Pokémon Platinum.
