Shadow mario

is an evil doppelgänger of Mario and the main villain of Super Mario Sunshine. He has the same appearance of Mario, except that his body is blue and water-like, and his eyes are red. He also has an unusually long, red tongue. Shadow Mario wields the Magic Paintbrush, an invention created by Professor E. Gadd. Using the brush, Shadow Mario can create toxic Goop and even some enemies. Midway through the game, it is revealed that Shadow Mario was Bowser's eighth child, Bowser Jr., in disguise. Using a bandanna with an image of Mario's mustache on it, Bowser Jr. could make him self look like Mario. It is unknown how Bowser Jr. acquired the paintbrush. However, it is suggested that Professor E. Gadd gave the brush to him.
note that cosmic mario is also alike like shadow mario
Cosmic Mario is a character in the game Super Mario Galaxy. He appears as a starry clone of Mario, similar in appearance to Shadow Mario; interestingly, if the player collides with Cosmic Mario, Star Bits come out. When a Cosmic Comet is orbiting a galaxy, Cosmic Mario will appear from it and challenge Mario to a race. Mario then has to race through numerous obstacles against Cosmic Mario to get to the Power Star.
If the player is playing as Luigi, Cosmic Luigi will appear in place of Cosmic Mario. Cosmic Luigi is far more intelligent, making use of short cuts and many long jumps. As a result, he is much faster than Cosmic Mario. This is done to add some extra challenge when playing as Luigi. While similarly named, the character Cosmic Wario, from Wario: Master of Disguise, has nothing to do with Cosmic Mario or Cosmic Luigi.Cosmic Mario has a very high-pitched voice. Cosmic Luigi's voice sounds the same as Cosmic Mario's, despite the fact that normal Mario and Luigi have different voices. When Cosmic Mario appears in front of Mario, he says, "Come on!" while Cosmic Luigi only says, "Let's go!"
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.
