Colosseum Battle is one of two types of challenge battle modes in Pokémon Colosseum's Battle Mode. While Battle Now provides rental teams to allow players to battle immediately, Colosseum Battle requires the player to use Pokémon they have already obtained. Players can take part in battle challenges against AI opponents or face other human players in Gang Battle. Winning against AI opponents awards the player Poké Coupons. These can be awarded either in Colosseum or a GBA game using the party team. In the Japanese Colosseum Bonus Disc, this is the only way to earn Poké Coupons in GBA games to receive rewards.
