Max Raid Battles are a special feature in the Pokémon games, allowing players to team up with others to battle powerful Dynamax Pokémon. These battles take place in glowing dens found throughout the game world, where players can encounter various wild Pokémon that have increased size and strength. During a Max Raid Battle, up to four players can join forces to defeat the Dynamax Pokémon within a time limit. If successful, players have the chance to catch the defeated Pokémon and earn valuable rewards, making these battles a fun and cooperative experience for trainers.
