The list of legendary Pokémon becoming available in Niantic Labs smash hit game, Pokémon Go is growing with this time Groudon appearing at Gyms.
Groudon is a ground-type Pokémon from the Hoenn region, the latest region to have its Pokémon begin appearing in the game. Groudon is becoming available as part of the Raid Battles that occur at gyms in your area. As part of the new battle mechanics you’ll need the requisite Raid Pass to battle for the chance to capture Groudon, so keep raiding gyms.
Groudon is available until 1pm PST on January 15 next year (wow, that seems weird saying that) – that’s 8am on January 16 AEDT for those playing in Australia. Get out there and catch them while they’re there.
