Nixie is a Nixel.
Unlike other Nixel minions, he can speak in clear English, which gives him a clearer personality. He appears slightly grumpy, and whines when he does not get his way.
Nixie appears as a standard pointy eared Nixel. However, unlike other Nixels, he has a solid band connecting his body to his ears. His teeth are also somewhat curved, compared to the straight points of the other Nixels.
While grumbling about his dislike of Mixels, he spies Flain, Seismo, Volectro, Kraw, Slumbo, and Chomly arguing about who gets to use a Cubit first. Seismo, forgetting his strength, ends up stomping during a temper tantrum, which causes an earthquake that sends Nixie flying in the air, nearly landing on Flain's burning head.
However, Kraw crashes into him, knocking him in the air again, where he strikes a napping Slumbo and wakes him up, which causes him to fly in the air again, this time landing in a tree. All the chaos makes Volectro upset, causing his static field to go off, and making Nixie stick to his head. While the others try to pull Nixie off of him, he stays stuck.
Eventually, the other Mixels leave to get another Cubit, and Volectro decides to keep Nixie for a pet; giving him his nickname, much to Nixie's displeasure. ("LEGO Mixels: Activity Book")
