Thundurus cannot be in found in Pokémon White 2. However there are 2 ways to putting Thundurus in White 2, 1 of which is by arranging a trade for a Thundurus with another player and the other option is to use the Nintendo 3DS eShop application called Dream Radar in order to capture Thundurus and then you can use the Dream Radar to send the captured Thundurus over to your Black 2 or White 2 game.
