Pokemon GO gets its first Generation 3 Legendary Pokemon, but only for a limited time
Groudon is a Ground-type Legendary Pokemon that was originally discovered in the Hoenn region. He should start showing up in Raid Battles around the world in the next couple of days. Players should look for Groudon at Gyms near them if they want to be among the first to catch the Legendary Pokemon.
Even if you won't get lucky, there's a high chance the Niantic will bring yet another Legendary Pokemon to take Groudon's place once he goes away next month.
