In addition to event-themed Pokemon in Tier 1 and Tier 3 Raids, there will be two Legendaries and a Mega Pokemon available to battle during the event!

The following Raid bosses will be available to battle from 10 AM local time on August 19 to 8 PM local time on August 22, 2023 – the entire of the Noxious Swamp event:

  • 1-Star
    • Grimer
    • Alolan Grimer
    • Hisuian Qwilfish
    • Hisuian Sneasel
  • 3-Star
    • Galarian Weezing
    • Druddigon
    • Turtonator

    • Mega Salamence
  • 5-Star
    • Xerneas (knows Geomancy)

Even if you have caught Xerneas and Yveltal before, you may want to catch another one. This is because if you catch either of them during the Noxious Swamp event, they will know an exclusive featured attack!
