Once a Pokémon's Unite Move gauge is fully filled, they will be able to use a powerful Unite Move. Leveling up can also help to charge the Pokémon's Unite Move gauge. While battling, the player is also able to level up once they defeat enough Pokémon and can even make their playable Pokémon evolve depending on the species. The winner is decided by the higher final score of both teams once the battle timer is over. The player is able to heal by standing in their own team's goal zone or scoring any around of points.

Once a Pokémon is defeated, opponent or wild, the player collects Aeos Energy in Unite Balls which can then be carried to the opposing team's goal zones, dispensing the energy and collecting points for the team. During gameplay, the player will partake in team-based battles called Unite Battles in which two teams of five, four or three Pokémon battle against each other and other wild Pokémon.
