The official Pokémon website has announced that players of Pokémon Sword and Shield can face Various Meowth, including Shiny Galarian Meowth, in Max Raid Battles from April 30th, 2021 until May 2, 2021, at 4:59 p.m. PDT.

Face Various Meowth, Including Shiny Galarian Meowth, in Max Raid Battles

You can encounter Meowth, Alolan Meowth, Galarian Meowth, and Gigantamax Meowth in Pokémon Sword and Pokémon Shield.

You'll have a meow-velous time when you take part in Pokémon Sword and Pokémon Shield's Meowth Festival Max Raid Battle event. Until May 2, 2021, at 4:59 p.m. PDT, Meowth, Alolan Meowth, Galarian Meowth, and Gigantamax Meowth will appear in Max Raid Battles—if you're lucky, you might even encounter a Shiny Galarian Meowth during the event.

For an opportunity to encounter these Pokémon in a Max Raid Battle, you'll need to connect your Nintendo Switch system to the internet through Y-Comm or by selecting Mystery Gift in the X menu, then selecting Get the Wild Area News. After that, whenever you see a pillar of light shining from a Pokémon Den, you can walk up to the Pokémon Den and interact with it to start a Max Raid Battle with a Dynamax Pokémon. Usually, there'll be an extremely small possibility a Gigantamax Pokémon will appear instead of a Dynamax Pokémon, but during an event, certain Gigantamax Pokémon are more likely to appear. This event does not affect the Pokémon encountered within Dynamax Adventures.

Be sure to read our Pokémon Sword and Pokémon Shield Max Raid Battle Tips article for advice on how to topple these clawesome opponents. Don't wait, though—you don't want to miss out on the chance to add some purr-fect Pokémon to your team!
