A hellhoun is a demonic dog of Hell, found in mythology, folklore and fiction. Hellhounds typically have features such as an unnaturally large size, a black fur color, glowing eyes, super strength or speed, ghostly or phantom characteristics, and sometimes even the ability to talk. They are often assigned to guard the entrance to the world of the dead or undertake other duties related to the afterlife or the supernatural, such as hunting down lost souls or guarding a supernatural treasure.
