This is a Press Release by, The Pokémon Company
The Legendary Pokémon Rayquaza will be making an encore appearance in Pokémon GO Raid Battles from March 15 at 1:00 p.m. PDT through March 18, 2019, at 1:00 p.m. PDT. Rayquaza is an extremely powerful Pokémon, so make sure to catch the Sky High Pokémon before it flies away again.
If you evolved Swinub into the Ice- and Ground-type Mamoswine during the most recent Community Day or if you caught some of the Dragon-type Legendary Pokémon that have been available in Raid Battles lately, you’re sure to have a leg up against Rayquaza. Get your strongest Pokémon ready for battle, and good luck, Trainers!
