Tornadus

Tornadus (Japanese: トルネロス Tornelos) is a -type Legendary Pokémon first introduced in the Generation V games Pokemon Black and White. It is also a Pokémon that is only a male. You have to go to route 7 and go into a house and when you come out there is Tornadus. It is somehow related to Thundurus and Landorus. It is a version exclusive for Pokémon Black. If Tornadus is in the same Route as you, it will start pouring rain. The message boards will sometimes say: a mysterious storm has appeared in Route (any route really) and this means that Tornadus is in that Route.
