In this innovative game, players can upload Pokémon from their Game Boy Advance games Pokémon Ruby and Pokémon Sapphire, and battle against friends on their televisions through Nintendo GameCube. With a collection of arenas to choose from, players can enter their Pokémon in a tournament or battle it out in four-player multi-battles, making each experience unlike the last. Players also can join with a friend to combine strengths in new two-on-two battles and demonstrate their Pokémon prowess as a team.
