It’s been a good long while since Latios, the blue Eon Pokémon, has been seen out in the game world. People hunting for perfect Pokédexs and shiny legendaries were at a loss the entire time. But they may have a chance once again. Latios is returning for a limited time!

According to an announcement on the Pokémon GO live blog, Latios will appear in special Raid Battles around the world for a single week. Here are the details:

• Start date and time: Monday, April 15, 2019, at 1 PM PDT
• End date and time: Monday, April 22, 2019, at 1 PM PDT

During this time, Latios will appear in Raid Battles, including rare instances of shiny variations. So stock up on potions, revives, and Ultra Balls while you still can.

There’s no word as to whether Latias will also return soon, but we can’t imagine they’re too far behind.
