Cosmic Clone

Cosmic Clones (or Shadow Clones) are shadowy duplicates of Mario that first appeared in Super Mario Galaxy 2.

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, performing every movement the plumbers make. Boards usually warn the plumbers that Cosmic Clones are present in the area, although they also appear when a Clone Comet orbits a galaxy.

Cosmic Clones will do whatever Mario did, even if the landscape has recently been changed. For example, they will still appear to jump on a platform even if the platform had disappeared after Mario used it. 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 disappear screaming loudly for a few seconds and leaving behind three Star Bits each.

Super Mario 3D Land
A Cosmic Clone appears only in the Special Worlds in Super Mario 3D Land, and it resembles Small Mario, though it differs in size in certain levels. A big Cosmic Clone's voice has a low pitch, and it is twice the size as its usual. It can also destroy Brick Blocks upon contact. It seems to conduct the same tactics as Cosmic Mario, with the addition of it attacking Mario if he gets in its way, and it has a purple outline instead of a red one. 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, 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.

Trivia

 * The Cosmic Clone's theme is a remix of the Super Mario Bros. overworld and underground theme, like Cosmic Mario's (or Cosmic Luigi's) theme from Super Mario Galaxy.
 * Cosmic Clones also share the same tone of voice as Cosmic Mario and Cosmic Luigi: a high-pitched voice that is strikingly similar to Shadow Mario's.
 * 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.
 * Cosmic Clones are always clones of Mario in Super Mario 3D Land, even if Luigi encounters them.
