Cerberus

Cerberus (Greek mythology) is best known as the guardian to the gates of the Underworld. In Greek mythology Cerberus is depicted as a dog with three ferocious heads and the tail of a snake.  He is one of the great Greek monsters born unto Typhon and Echidna. His sole task is essentially be the "bouncer" of The Underworld.  As the rules go, only the dead may enter the Underworld, and none may leave. There are only a couple of myths in Greek mythology where a hero gets the better of Cerberus. The first is when Orpheus (Greek mythology), the famed musician, sneaks into The Underworld by lulling the usually unstoppable Cerberus to sleep with his beautiful music. The second myth is when Hercules (Greek mythology), with the approval of Hades (Greek mythology), the god of the Underworld, gets Cerberus in a choke hold, knocks him out, and kidnaps him. He is eventually returned to his post where he remains to this day. Other than these myths, the three-headed hound of Hell is an unmatched force for anyone trying to get in or out of Hades without express permission.
==Summoning Requirements==
In order for any demon to summon Cerberus to their aid they must be a Demon Lord. Cerberus was loyal to only Hades and Lucfier but since their passing, it has allowed itself to only be summoned by Demon Lords and nobody else.
