As a Scout Fairy, she protects all of Pixie Hollow from any dangers or threats, also leads a team of fellow scout fairies who follow her commands without question.
She is known to be quite tough and the kind of person who will fight until the fighting is done. She never backs down and will do whatever it takes to ensure the safety and well being of Pixie Hollow and its people.
While being the main antagonist in Legend of the NeverBeast, Nyx is not evil, but will do anything to keep the fairies in Pixie Hollow safe from any danger or dangerous animal. She can also be a little rude and mean to Fawn and she dislikes Gruff. But after Nyx destroys a rock tower, lighting causes fire in Pixie Hollow and was almost struck by lightning but Gruff saved her. Nyx was shocked that Gruff saved her life. After the storm was over and everyone thought Fawn was dead, everyone was sad, and so was Nyx. But after Gruff brought Fawn back with electrical energy, all the fairies were happy and relieved to see Fawn is okay and alive, even Nyx. When the fairies say goodnight to Gruff when he goes back into hibernation, the fairies made him a bed, a fluffy pillow, a water bowl, a nightlight and a breeze, Nyx said that Gruff also earned the enduring respect of a grateful Scout for saving her from the lightning.
