Cosmic Clone

Cosmic Clones (or Shadow Clones) are shadowy duplicates of Mario that first appeared in Super Mario Galaxy 2. They copy Mario or Luigi's every move, even copying their death animation if they die. They appear to be a successor to Cosmic Mario: they are strikingly similar to them, sharing the same voice as them, and their theme is the Cosmic Comet theme from Super Mario Galaxy (a half-step higher pitch and an edited opening section, which in turn is a cover version of the Super Mario Bros. overworld and underground theme). The only difference is their color and the Cosmic Clones' glowing yellow eyes.

Super Mario Galaxy 2
In Super Mario Galaxy 2, Cosmic Clones are created once a certain point is reached in a galaxy and will follow behind Mario or Luigi, mimicking every movement he makes. Boards usually warn Mario that Cosmic Clones are present in the area, although they also appear when a Clone Comet orbits a galaxy.

Cosmic Clones will mimic whatever Mario or Luigi does, even if the landscape has recently been changed. For example, they can jump on a platform where Mario or Luigi were standing, even if it has disappeared or moved. If Mario or Luigi get hit by a clone, they receive damage and the clone vanishes, with the rest of the clones then mimicking the plumber taking damage. Once the way forward is revealed, the clones scream, disappear, and release three Star Bits each.

Super Mario 3D Land
Cosmic Clones appear only in the Special Worlds in Super Mario 3D Land, and they resemble Small Mario. Regardless of which character encounters a Cosmic Clone, it will always resemble Mario's body and hair more than Luigi's, suggesting that the Cosmic Clone is copying Mario only. A big Cosmic Clone's voice is slower and has a lower pitch, and it is four times the usual size. It can also destroy Brick Blocks upon contact. It functions identically to the clones in Super Mario Galaxy 2, but it has a purple outline instead of a red one, and only one appears instead of a group. Mario or Luigi can destroy it by touching it while invincible; normal-sized clones give three coins upon destruction, and large ones give ten. Upon reaching a certain area (normally the level's halfway point), the Cosmic Clone disappears. If the player leaves that area, the Cosmic Clone will appear again, even if it has been destroyed with a Star.

 * Only the first clone will make noises when jumping. If the player is hurt by the first Cosmic Clone, the other ones will not make any noises.
