• BEARER OF DEATH? "Hellhound" is only one of many names used to describe ethereal, black dogs that roam hillsides and graveyards. With their glowing red eyes, super strength and speed, and a tendency to trail fire and brimstone in their wake, Hellhounds make for a terrifying messenger from the underworld. They are said to have been created by a group of ancient demons to serve as heralds of death, and seeing a Hellhound — some say once and others claim it takes three sightings — inevitably leads to the viewer's demise. Hellhounds boast many titles, including Black Shuck, Cerberus, Garm and Perro Negro. In the popular Harry Potter series, author J.K. Rowling referred to a menacing Hellhound as "The Grim."
