Pokémon Colosseum - Nintendo GameCube

Travel through the Orre region as Wes and take on the criminal organization Cipher, which has turned Pokémon into dangerous Shadow Pokémon. Battle alongside your Pokémon in Double Battles, catch opponents' Shadow Pokémon, and then try to purify them.
Pokémon Colosseum combines classic Pokémon battles with an extensive story and fully realized 3D environments. The focus on Double Battles and catching and purifying Shadow Pokémon gives the game a distinctly different approach from traditional Pokémon games.
