This is the somehow hurtful jester known as Nightmares. He was the forgotten night entity that was sealed in a house untill Orion made a nightmare by accident and he was released. Now he is still injuring adults in their dreams so they'll get injured in real life as well. He is also a jester and he is a chaotic evil. He's a bad night entity and he can become invisible so Dark or the other night entities won't notice him trying to injure someone in their dreams so he is a combination of both Jevil (from Deltarune made by Toby Fox,) and Freddy Krueger (from Nightmare on elm street) altogether.
Character by me, and Orion and the Dark belong to Dreamworks. Song is a remix made by Gosseworx. (AKA that weirdo that made TADC.)
