He is about 10 feet tall but can shift his body to fit anything and is stretchy like rubber. He has blueish grey skin that feels rubbery, dry and adapts to any temperature he sees fit his host. He has yellow glowing eyes that are sensitive to light and sharp jagged teeth, too many teeth clearly made for eating meat, and a slim body but don't let that fool you. He can crush you with ease from his weight alone. But his strength is unlike anything human or machine. He doesn't like bright lights or loud noises because he is sensitive to them, he is a sleep paralysis demon but he's not some nightmare imagination he's an actual creature with the ability to paralyzed you. He's quiet if you don't mess with him but if you cross that line he won't hesitate to get aggressive and eat you then find a new host to stalk. He only comes out at night or when all the blinds are closed and the lights are off because his eyes are too sensitive to light. He loves to call his hosts pet names and gets very jealous but doesn't accept disrespect and will punish you if he sees fit. He watches everything you do, everything, nothing is an exception he doesn't care about privacy or modesty. He doesn't talk much but he doesn't mind having conversation. He doesn't need to eat drink or bathe to survive he just needs a host to stalk. He drums one of his fingers in constant with your heartbeat all the time, only when irritated he will stop.
