Battle Party

A Battle Party is a loadout system that allows a Trainer to create and name teams of up to six Pokémon in Gym battles and Raid Battles or three in Trainer Battle from their Pokémon collection for quick access when participating in battles. It is divided into sections GREAT LEAGUE, ULTRA LEAGUE, MASTER LEAGUE and GYMS & RAIDS. Trainers can have a maximum of five teams in each category.

During the initial beta phase, battle parties were saved to a single device, so parties did not transfer if a Trainer bought a new device or used multiple devices to play Pokémon GO. Once the feature was fully launched, battle parties carried over to each device that a Trainer logs into.

With the introduction of Trainer Battles, Trainer can construct Battle Parties for each league. However, only three Pokémon can be assigned in the Battle Party of this mode.

Creating a party to battle Team GO Rocket members uses one slot in Master League section.
