A trainer can choose their favorite Pokémon from their collection to become their Buddy. This system opens up unique in-game rewards and experiences. The chosen Pokémon will appear next to its trainer's avatar on the profile screen. As the trainer moves about, bonuses will be rewarded such as Candy for walking together. The Buddy will be able to be swapped out with another Pokémon at any time. A Buddy cannot be assigned to a Gym.
There are five Buddy Types: Medium, Big, Shoulder, Baby and Flying.
