The Legendary Groudon and Kyogre will return to Pokémon Go raids from tomorrow in the UK. (If you're in the US, you'll see them at 1pm Pacific today.)
Their return comes as part of a new two-week event focused on Pokémon from Hoenn, which will run until 29th January at 9pm UK time.
Groudon and Kyogre are two of the best creatures in the game. They're commonly among the best attackers for tackling other raid bosses or taking down gyms. If you don't yet have a good one (or two, or six) then now is your chance.
As part of the Hoenn event, shiny versions of common species Zigzagoon and Taillow will be available for the first time. And Groudon is expected to be shiny too (Kyogre was already when it returned last year).
Shroomish will get a special move - Grass Knot - when evolved during the course of the event, which will make the resulting Breloom one of the best Grass-type Pokémon in the game.
7km eggs will get a shake-up with Hoenn species added in, and there will be new avatar clothing themed around Hoenn baddies Team Magma and Team Aqua.
And that's all on top of this weekend's Feebas research day event, which will see the fish available shiny for the first time via tasks at certain PokéStops - but only between the hours of 10am and 1pm UK time.
