This is a complete list of Pokémon in the order dictated by the new Unova regional Pokédex, meaning that Victini and then the starter Pokémon from Unova will appear first, followed by other Pokémon native to the Unova region, as well as those from other regions that appear in Pokémon Black and White Versions 2.

- In Pokémon Black and White, it was the only regional Pokédex aside from that of Kanto to only contain Pokémon of one generation.
- The New Unova regional Pokédex contains 301 Pokémon, the largest amount so far.
- This is the only regional Pokédex where a starter Pokémon is not first in the listing and the only regional Pokédex to have a Pokémon numbered #000.
- It is impossible to get a "seen" Pokédex entry for Rufflet in Black 2 and Vullaby in White 2 without trading with another player, because they cannot be found in the wild in the respective games, and no in-game Trainers use them. However, their respective evolved forms Braviary and Mandibuzz are used by Trainers on Victory Road in both versions.
