A Raid Battle is a cooperative gameplay experience that encourages Trainers to work with other Trainers to defeat an extremely powerful Pokémon known as the Raid Boss. Before a Raid Battle begins, all Pokémon assigned to the Gym will return to their owners, and a large Egg will appear atop the Gym. When the countdown above the Egg reaches zero, the Raid Boss will be revealed.

Upon using a Raid Pass to join the battle, the Trainer and up to 20 other Trainers work together to defeat the Raid Boss. If a Raid Boss is successfully defeated within the five-minute time limit, those Trainers have the chance to catch an extra powerful Pokémon of their own.
