(you see Nightmarionne under your bed about to get you*
While Nightmarionne shares similarities with his original counterpart, Nightmarionne has many qualities which sets him apart from the Puppet. Nightmarionne appears to be the "skinniest" of the animatronics. He has a very thin, black body, which resembles a human skeleton. His limbs are made out of thick ribbons of the same material as the rest of his body, braided together, ending in points or knots. From the ends of his short arms protrude three long, spindly, pointy tentacles, each one bearing four white stripes. His knees are set low on his body, and his feet are simply braids of material that end in a fine point. His torso is incredibly thin in the middle, and his upper chest appears to have a rib cage on the outside. Unlike his original counterpart, he lacks the three buttons on his chest, or the striping on his legs. His face is white, with small, black lips, and thick, black, vertical stripes, reaching from the bottom of the eyes to the top of the mouth painted on. His mouth is open in a wide, sinister grin, revealing pointed, sharp-looking teeth, his upper jaw revealing more teeth than the lower. His eyes are black, save for rather small, round, white pupils shining in each socket. When light lands upon his face properly and illuminates his eyes, it is revealed they are quite similar to the eyes of the animatronics from the third game. They are white and round, too small for the sockets, and appear to be bloodshot. His pupils also glow, emanating an eerie, white light. He also lacks rosy cheeks. The texture of his body has detailing that appears similar to leather, though it seems to be sleeker, and fairly shiny. His face is clearly much smoother than the rest of his body. Based on its quotes in Ultimate Custom Night, Nightmarionne is wicked, vengeful, and sadistic. As with the other nightmares, he opportunistically torments his victims. His voice is low-pitched, distorted, and also stutters in a glitch-like fashion.
