Time to GO out and raid!
You can expect to see new Legendary Pokemon hitting raids starting on April 2nd! Latias and Latios are zooming into Legendary Raids at gyms!
This Dragon/Psychic pair are ready to battle. Though your regional will determine which one you will see at your local gyms. Latias will appear in Raid Battles across Europe and Asia, while Latios will appear in North America, South America, and Africa.
These Legendary Pokemon are known to be roaming. That is why you will see Latias and Latios swap regions on May 8th. That will give trainers all over the world to capture to capture this pair.
No matter what, you will have until June 5th to capture Latias and Latios. Best of luck in your raiding!
