Luigi started his hero role in Mario is Missing, however, up to Luigi's Mansion, his brother Mario was always the one in the spotlight. Now in Super Mario Galaxy and Mario Galaxy 2, he is an unlockable player. He also seemed to go on his own adventures during the events of Paper Mario: The Thousand Year Door, where he got some practice in kart racing on Circuit Break Island, which, coincidently, is a course in this game.
