This storm-stirring Pokémon is said to cause the seasons to turn by whipping up the air. I suspect its humanlike form to be a false one.
Tornadus is a Flying-type Pokémon. It takes double damage from Electric, Ice and Rock, resists Grass, Fighting and Bug, and is immune to Ground. Its base stats add up to 580: the highest is Special Attack (125) and the lowest is Defense (70).
It does not evolve, and no other Pokémon evolves into it. Its ability is Prankster, and its Hidden Ability is Defiant. It cannot breed: it is in the Undiscovered egg group. In Scarlet and Violet it learns 17 moves by level-up and 48 by TM.
