Back in May, Pokemon Go developer Niantic announced it would be bringing three Legendary Pokemon back to the game, beginning with Cresselia. If you've yet to capture one, however, your time is quickly running out. The Lunar Pokemon is scheduled to leave Raid Battles this Tuesday, June 18, making this your last opportunity to catch it–and possibly find a Shiny Cresselia.
If you're hoping to add Cresselia to your collection, you'll first need to team up with other players in-person and take on the Legendary Pokemon in a Raid Battle. Cresselia is a pure Psychic-type, so you'll want to bring along Ghost, Dark, and Bug Pokemon like Giratina, Tyranitar, and Scizor when you battle it. If you manage to defeat Cresselia, everyone who participated in the Raid will receive a handful of Premier Balls along with an opportunity to catch it.
Immediately following Cresselia's departure, the Gen 3 Legendary Kyogre will return in Pokemon Go. It'll appear in Raid Battles until June 27; after that, it'll be replaced by its Pokemon Ruby counterpart, Groudon, which will be available until July 10. Just as with Cresselia, you'll also have a chance of encountering Kyogre and Groudon's Shiny forms when each Legendary returns to Raids.
Niantic's annual Pokemon Go Fest event is now underway in Chicago. To celebrate the occasion, the Water-type Pokemon Horsea will spawn much more frequently than normal from now until Go Fest ends on June 16. Not only that, but you'll also have a chance of finding Shiny Horsea. Those who are attending the event, meanwhile, can find Shiny Abra, as well as Alolan Vulpix, a special Eevee wearing a floral crown, and the Mythical Pokemon Jirachi. If you can't attend Go Fest in-person, you can still participate in Global Challenges to help unlock in-game rewards and bonuses.
