Pokémon Go’s Raid Battles are like gyms on hard mode. They’re a multiplayer-based, extra-difficult fight against a single strong Pokémon. A group of players work together to take down this Boss Pokémon in the hopes of earning some special items and maybe even catch the Pokémon. The tier-based system ranges in difficulty from level one to level five, with five being the toughest. Try to gather as many people as possible to take these on.

Note: All trainers must be at least level five in order to participate in raids.
