Gigantamax Snorlax, Gigantamax Machamp and Gigantamax Gengar are appearing more frequently in Max Raid Battles for a limited time in Pokémon Sword and Shield. Trainers can check out the Pokémon Dens that dot the Wild Area to battle this gigantic form of Snorlax. A connection to the Internet is required to participate in Max Raid Battles. Connecting their Nintendo Switch system to the Internet will automatically enable Trainers to encounter the latest Pokémon appearing in the Wild Area. Players can also achieve the same results manually by opening the X menu in their game, selecting Mystery Gift, and then selecting Get the Wild Area News.
