Two new legendaries, Latios and Latias from Ruby and Sapphire, are being added to Pokémon Go today.
The twin Eon Pokémon are replacing Lugia, who was available for a limited time, and players can find them in the world right now.
Though both Latios and Latias have arrived in the game, they will both be in different parts of the world for, and for a limited time.
Latios can be found in North America, South America, and Africa. Latias will appear across Europe and Asia.
On May 8th, the two Pokémon will swap regions, where they will stay until June 5th.
As is the case with all legendary Pokémon, Latios and Latias can only be found in Gyms and Raid Battles. Players will need to join forces in order to defeat them, and attempt to catch them.
They are both Psychic/Dragon type, and so they are weak to Fairy and Dark-type Pokémon.
Niantic will also introduce Pokes like Tyranitar and Mawile, which will give players a chance at amassing stronger squads to take on Latios and Latias.
In other Pokémon Go-related news, Niantic recently introduced a new quest system, and a chance at catching Mew.
