A new Max Raid Battle event featuring uncatchable Magikarp is now underway in Pokémon Sword and Shield for April Fools’ Day. To take part in a Max Raid Battle, you’ll need to connect your Nintendo Switch system to the internet. Then, when you see a pillar of light shining from a Pokémon Den in the Wild Area, you can walk up to the Pokémon Den and interact with it to start a Max Raid Battle with a Dynamax Pokémon.
