The legendary Uxie, Mesprit, and Azelf appeared in Pokémon GO recently. And thanks to heavy user participation, developers Niantic are bringing them back for an extended time!

Detailed in a series of Twitter posts, Pokémon GO will feature Uxie, Mesprit, and Azelf in Raid Battles around the world for the near entirety of May. From now until May 27, the three legendary Pokémon will appear in their designated regions as Raid Battles.

• Uxie is limited to the Asia-Pacific Region
• Mesprit is limited to Europe, The Middle East, Africa, and India
• Azelf is limited to North and South America and Greenland

But wait! There’s a rare chance that you’ll come across one of these Pokémon in the wild.

Psst… If you’re extraordinarily lucky, you may encounter these extremely rare Legendary Pokémon in the wild in their different regions even after the event.
