Nikusa is the void queen who appears in Friday Night Funkin': Entity. She was created by SugarRatio. She is the final opponent of Friday Night Funkin': Entity, facing off against Boyfriend in the final song, that being Promenade. Due to the number of sketches and positive Tweets about her from SugarRatio, Nikusa is considered to be one of his favorite characters in the mod.

Nikusa is a busty, 10-foot tall, pure white stick figure with pink eyes that fades to orange. She wears a black crown and choker, as well as a dark grey, low-cut jumpsuit underneath a long, light grey, short-sleeved gown, both of the latter having grey trims, and topped off with a black and grey belt. She has long white hair with a pink underside, which cuts off over the sides of her head and just below her rear. She holds a pink microphone in her left hand. Nikusa has an enigmatic and alluring personality, characterized by a friendly and flirty demeanor despite being the ruler of the Void. She is described as jovial and often uses kind words like "dear" or "honey". However, beneath this charming exterior, she can be seen as a lonely cosmic horror who may be using others for her own agenda or to fill a void.
