Nixels are the enemies of the Mixels and the primary antagonists.



Nixels are small and seemingly harmless; but they are actually vicious, annoying, crazy and destructive creatures who are spread all over the land of the Mixels. They live to tear down and break apart the world around them, including any combinations that the Mixels create. There is nothing the Nixels hate more than when two or three Mixels combine together and get super powers. The Nixels have made it their mission in life to put an end to such crazy creativity all together. The only way to do this is to hide and destroy the cubits which enable the Mixels to combine in the first place. When they swarm together, they can break apart a Mixel in seconds. They are shown to not be very intelligent, as they are easily confused (such as when they stand at attention towards an ice sculpture of Major Nixel in Wrong Colors), and have poor speech capacities, only being able to say single words and very simple phrases.

Physical Appearance

Nixels are very, very small. So small, in fact, that they can be easily crushed by Seismo's large feet. They have little ears, arms, and legs. When in their armor, they are mostly black, with the exception of their white faces peering through a circular hole in the front. It is possible that the black outer shell of a Nixel is like armor since it is shown that they can pop right out and run around without it. It is unknown how they control the hands in the armor, as they have no hands when outside of it. Their arms are also retractable, as demonstrated in Nixel "Mix Over". Nixel armor has three variants: slope ears, cat ears, and flat tops. However, there is a member that is an oddity to these rules. He is Muscle Nixel, and is about the size of Major Nixel and is very buff. Even King Nixel, their leader, is very large; being the largest overall character in the franchise. However, this is only due to him being made up of individual Nixels. In LEGO form, they share several common features, such as a white, spherical, printed face; a black, squarish body; small black arms; and small black nonfunctional legs. Small variations are present in each of the three known Nixels, such as size, building technique, pieces, and shape. Two different faces are currently in production; two of the Nixels, although their bodies are different, share the same face.
