Pokemon Go's Luminous Legends Y event kicks off tomorrow, May 18. The event is divided up into two parts and introduces a few new Gen 6 Pokemon to the game, including the Legendary Yveltal, which will be appearing in five-star Raids throughout the entire event. We've rounded up all the most important details about the event below.

Luminous Legends Y Part 1

　　Additionally, Niantic will offer Team Go Rocket-themed Timed Research tasks during the first part of the Luminous Legends Y event, as well as some exclusive Field Research. Completing these tasks will lead to encounters with Dark-type Pokemon like Galarian Zigzagoon and Scraggy. Certain Dark Pokemon like Alolan Rattata, Alolan Grimer, Sneasel, Poochyena, and Stunky will also hatch from 7 km eggs, while Alolan Meowth and others will appear as Raid bosses.

　　Finally, Niantic is holding a collective challenge during the first part of the event. If players can collectively defeat 25 million Team Go Rocket grunts between May 15-23, the studio will offer a few bonuses during the remainder of the event. First, you'll earn triple the usual amount of XP for catching a Pokemon. Galarian Zigzagoon will also be available as a one-star Raid boss, and you'll have your first chance to find a Shiny Galarian Zigzagoon in the game.

Luminous Legends Y Part 2

　　Beyond that, many of the same wild Pokemon featured during the first part of the event will continue to appear in the wild, as will Eevee, Ralts, Spritzee, and Swirlix. Certain Fairy-type Pokemon (or Pokemon that eventually evolve into Fairy types) like Cleffa, Igglybuff, Togepi, and Azurill will also hatch from 7 km eggs.

　　Finally, there will be more event-exclusive Research tasks. Completing these will lead to encounters with Eevee and some of its evolutions. You can read more about the event on the official Pokemon Go blog.

　　In the meantime, the Luminous Legends X event is underway until May 17. As part of that, the Legendary Fairy Pokemon Xerneas is appearing in Raids for the first time. New Field Research tasks for May are also live through the end of the month.
