B2W2 drops Black and White's Unova-only restriction. Old favorites like Arcanine and Lucario are available from the early game alongside Gen 5 picks. New areas and different gym leaders change where you find Pokemon compared to the originals. Same 649 total roster, much wider team options from the start.
Showing 335 Pokemon: the regional Pokedex plus transfer-only species.
How the B2W2 Pokedex differs from Black & White
B2W2 dropped the Unova-only restriction from day one. The regional dex starts at 301 Pokemon, mixing classics like Arcanine and Riolu alongside Gen 5 species right from the opening routes.
Hidden Grottos scattered across Unova spawn Pokemon with their Hidden Abilities. Unova Link connects with another copy for extra encounter tables and difficulty settings. Same 649 ceiling as BW, but your team options are way broader from the start.

It's a direct sequel set two years later, not an enhanced version. New protagonist, new rival, partially different gym leaders, and new areas like Humilau City and the Pokemon World Tournament. Old Pokemon are mixed into the regional dex from the start. The story continues from where BW left off.
A postgame facility in Driftveil City where you battle gym leaders and champions from every past region. Red, Blue, Lance, Steven, Cynthia, and every other major trainer appears. Each uses their signature teams. It's a fan-service gauntlet with real challenge.
Still Generation 5, released in 2012 for the Nintendo DS. B2W2 are the only numbered sequels in the main Pokemon series. They use the same engine and national dex as Black and White but tell a new story with expanded content.
