The Hidden is one of Reikgon's Shadows. Created to hunt down and kill anyone humans infected with a certain unknown disease. Once a living person, they were infected with Reikgon's parasitic zombie virus and transformed into The Hidden, and invisible humanoid with red glowing eyes that are only visible as soon as it strikes its victim with its invisible knife. It likes to whisper to its victims before slitting their throats and is quite a large, heavy figure, making loud footsteps as it stalks.
