Cerberus is a giant canine who is shadowed and has three heads and red eyes on each head.
Cerberus first appeared in the movie, Hercules. He first appeared when Hades rides down the River Styx and all three heads fought over a steak they were fed by Hades. Hercules tamed him to get Hades' inner sanctum, though only a temporary turn driven by fear.
