Therian Forme Tornadus is a Flying-type Legendary Pokémon originally discovered in the Unova region. This strange avian guise is suspected to be Tornadus’s true form, and Tornadus has been sighted crossing the ocean while in this form. Learn which Pokémon will be most effective in Raid Battles against Therian Forme Tornadus, how to catch it after winning a Raid Battle, and how best to use the Cyclone Pokémon after you’ve caught it.
As a Flying-type Pokémon, Therian Forme Tornadus is vulnerable to Electric-, Ice-, and Rock-type attacks. When choosing six Pokémon for your Raid Battle lineup, it helps to choose Pokémon that have a Fast Attack and Charged Attack of one of these types if you want to deal as much damage as possible. It’s not necessary to choose only Electric-, Ice-, or Rock-type Pokémon, but a Pokémon that shares a type with these attacks will benefit from the same-type attack bonus, which will allow these attacks to deal an additional 20% damage.
If you have multiple Pokémon that know Electric-, Ice-, or Rock-type attacks, choose Pokémon with the highest CP and best overall stats. Remember that speed of victory affects how many Premier Balls you will receive at the conclusion of a successful Raid Battle, so bring your strongest Pokémon and defeat Therian Forme Tornadus as quickly as possible.
