You will have two days to try and capture the Legendary Regi Trio this month so if you missed out on it the last time, this is your chance. With Darkrai gone, Niantics will be offering Regirock, Registeel, and Regice in the game while we wait for the next exciting legendary Pokemon.
From now until the 4th of November 1 PM PT, the trio will appear in Raid Battles around the world. There is also a chance of encountering a Shiny version of the trio so you can still give it a go even if you have already captured them the last time.
With the trio added to the game, players will be able to see Pokemons that have a type advantage over the Legendaries on the map now. That includes Pokemons like Magnemite, Swinub, Aron, Spheal, Shuckle, Sneasel and more.
The Legendary Regigigas will be making its debut in EX Raids this month and we will also be seeing Cobalion, the Gen 5 Legendary Pokemon get added into the games soon.
