Cerberus is an antagonist who first appeared in Disney's 35th full-length animated feature film Hercules. He is a gigantic, monstrous black three-headed Rottweiler dog who is the guardian of the Underworld and works for his master Hades.

His vocal sound effects were provided by Frank Welker, who also did the vocal sound effects of Pegasus and the Hydra.



Cerberus first appeared when Hades rides down the River Styx and all three heads fought over a massive steak that they were fed by Hades. Hercules later tamed him to infiltrate Hades' inner sanctum, though it was only a temporary turn driven by fear.

Hercules: The Animated Series

Instead of being an adult dog, Cerberus appears as a rambunctious puppy and is one of Echidna's children, whom Hades has difficulties in controlling.

Kingdom Hearts

Cerberus makes an appearance and is a boss in Kingdom Hearts and Kingdom Hearts II.



  • Cerberus is based on the demonic hellhound guardian of the same name in Greek mythology.
  • Cerberus was the only Hercules monster in the animated film to not die.
  • In Hercules: The Animated Series, Cerberus looks much more like a Rottweiler dog.
