Cerberus is a chained vicious canine monster whose body made of ethereal and elemental energy with heads made of certain 3 elements, fire, ice and thunder.
He is the boss of Will Taylor's Delight City dream as he was set loose by Wizeman to hunt down NiGHTS and to destroy everything in his path. His arena takes place in a giant spooky cage within the realm of Nightmare.
In Greek and Roman mythology, Cerberus is a three-headed hound who guards the gates of the Underworld.
- Cerberus is not one dog with three heads but two dog-like nightmares connected by a chain which is actually the third dog.
- The part of the chain you push to make the heads clash is actually the third head. It isn't until the the second battle you face Cerberus that this is known.
- The name of Cerberus' theme is "Clashing Cerberus".
- When the player first fights Cerberus, Cerberus can be defeated in 40 seconds or so, as clashing their heads together three times can be done quickly by an advanced player.
