In Pokémon Black 2, Rayquaza cannot be caught within the game itself, as it is not available in the Unova region. However, you can obtain Rayquaza by transferring it from Pokémon Black, White, or any other game where it is available, such as Pokémon Emerald or the Pokémon Omega Ruby and Alpha Sapphire remakes. You can also use events or special distributions if they are available during your gameplay.
