Cosmic Clone

Character name is... Cosmic Clone.

Cosmic Clone is a mischievous cosmic demon that looks like a perfect replica of Mario. He's a villain with big plots, but he only shows up rarely.

Biography
Cosmic Clone was created during the big bang, but only took the form of Mario when he came to the Mushroom Kingdom. He spends his time thinking up complicated plans, and loves working with good villains. It IS hard to communicate with him, because he only speaks in high-pitched gibbersh. He absolutely hates Mario and seeks to destroy him - unless they happen to be golfing, go-karting, etc together.

Behind the Scenes

 * Despite being made of cosmic matter, you do not die of suffocation and head explosion when coming into contact with him.
 * His first appearance is in the Igloo episode, while his latest is set to be in "Locked Out."
 * He is apparently able to use the matter within himself to generate "Black Rooms of Death" that cannot be escaped from.
 * He can alternate between blue and red at will, usually going with red when angered.
