Pokémon Colosseum for the Nintendo GameCube is a follow-up to the popular Pokémon Stadium series on the N64. Connect your Game Boy Advance to your GameCube in order to battle with over 200 detailed 3D versions of Pokémon from the Ruby and Sapphire GBA games. As well as uploading characters into Colosseum, players are able to load exclusive Pokémon from the GameCube game and take them on the go with the Game Boy Advance. In addition to the tournament battle mode, Colosseum boasts a full adventure mode with a storyline. In this mode, players follow the trail of a mysterious organization that has been turning Pokémon into Shadow Pokémon.
