King Nixel is the leader of the Nixels, and the main antagonist.



King Nixel is a dark and powerful tyrant that will do anything to ruin fun in the Mixelverse. He is so intimidating that even just the sight of him makes his own army shake in fear, faint, or bow immediately. However, while undisguised, King Nixel is whiny and weak.

Physical Appearance

King Nixel presents himself as a tall and limber Nixel. His face is made up of the body of a flat-topped square Nixel with small pincers on the sides of his head, with a bushy black mustache and thick black eyebrows. His body is a long black cloak with pointy shoulder pauldrons, which conceals the fact that it is actually made out of other Nixels. His hands and fingers are dark grey while his fingers have sharp white tips. He wears a dark grey crown on his head. Without his disguise, he is simply a small flat-topped Nixel. His feet are more rounded than standard Nixels and he still has the small pincers on the side of his armor. His limbs are grey, instead of the standard black. His eyebrows are pointier than standard Nixels.
