Cosmic Mario is a shadowy character (who resembles Shadow Mario) who appears in the Super Mario Galaxy Longplay. He always appears when a Galaxy is under the effects of a Cosmic Comet. He challenges Mario and SMG4 to a race to the star. Every time he loses (which is every time), he gets furious and starts swearing and tries to get the star back but he always fails. He's normally a good racer but isn't very fast and sometimes makes mistakes. He's the only character character in the Super Mario Galaxy Longplay not to reappear in the Super Luigi Galaxy Longplay though his brother Cosmic Luigi appears replacing him. Cosmic Clones replace both in the Super Mario Galaxy 2 Longplay. Cosmic Clones also appear in the Super Mario 3D Land Longplay.
