Cosmic Mario

Cosmic Mario is a character that appears in Super Mario Galaxy. His physical shape is identical to Mario, while his outer appearance is blue with stars all over. If Mario or Luigi enter a galaxy when a Cosmic Comet is orbiting a galaxy, Cosmic Mario appears at the beginning at the level and challenge the player to a race. The player must then race through numerous obstacles and reach the finish before Cosmic Mario to earn a Power Star.

If the player is playing as Luigi, Cosmic Luigi will appear in place of Cosmic Mario. Cosmic Luigi utilizes short cuts and many long jumps. As a result, he is much more difficult to beat, and faster than Cosmic Mario.

Cosmic Mario appears to be the equivalent of Koopa the Quick and Il Piantissimo from Super Mario 64 and Super Mario Sunshine, respectively. Spooky Speedster, also from Super Mario Galaxy, is a racer as well.

Similar entities based on Cosmic Mario appear in Super Mario Galaxy 2 in the form of the Cosmic Clones and the Cosmic Spirit. Cosmic Clones are slightly different in appearance and mimic Mario's movements, all the while spawning more of themselves, usually in areas where if Mario waits too long, they'll multiply to the point where he can't get around and they'll catch up to him. The Cosmic Spirit is the equivalent of New Super Mario Bros. Wii ' s Super Guide Block, controlling Mario to guide him to a Bronze Star (the Gold Star can only be obtained without the help of the Cosmic Spirit).
