Landorus, Tornadus, Thundorus. Or Cobalion, Virizion, Terrakion. Tornadus is only available in Pokemon Black and Thundorus is only available in Pokemon White. You have to trade Thundorus (Tornadus) to Pokemon Black (White) To get Landorus. You have to get Cobalion before you can get Virizion and Terrakion.
Black only: Reshiram, Tornadus White Only: Zekrom, Thundorus
Since you have Pokemon Black, you cannot catch it in the wild, you can only do that on White. So what you have to do is either trade normally with a friend or you can go onto the Global Trade System which is in the Pokemon center and you speak to the nurse uptairs to the far right. You then type in Thundurus and you have to have a Pokemon that they want.
