The Demon (also known as The Monster from Another Dimension The Energy Monster, The Giant Nuclear Monster, The Evil Devil Creature, The Mutant Orange Beast, or The Dimension Giant Of Hell) is the secondary antagonist of the 1983 animated musical film Rock and Rule. It is the master of the infamous musician named Mok Swagger.

It was voiced by Iggy Pop.


Attempted releases

The Demon is a monster who was imprisoned in another dimension, and Mok sought to free it to give him immortality, legendary fame and ultimate singing. Mok tried several times throughout the film to unleash the Demon, all with disastrous consequences.

The Ritual

It was only when Mok realized that he needed an overload of power that he managed to create a gate to the Demon's dimension of hell.


The Demon came out of the gate in a burst of nuclear orange energy and tried to devour Angel, the victim Mok had chosen. However, Omar and the rest of his band appeared.


Together, Omar and his band fought the Demon, eventually driving it back with Angel's powerful singing Voice. However, Mok was terrified and attempted to thwart their efforts, realizing that the computer's prophecy about "no one" meant that more than one being was needed to stop the Demon. Mok tried to kill Omar, but Toad (the brother of Zip the one who sacrifice himself to save Omar), one of his henchmen, distracted him by kicking him into the portal in revenge for his brothers death, leaving him locked up in the other dimension with the demon.


Little is known of the Demon's personality or even its real name. However, it was awesome, as shown by how both Omar's band and Mok's henchmen react upon seeing the creature released. It seemed to be able to grant wishes - thus probably making it a type of Djinn - or perhaps even another wish-granting demon. It could only vocalize in growls, grunts and screams, and this might have been due to it being released, it had yet to regain full power. However, it could consume living matter, and sought destruction. Mok was eager to meet the Demon yet he was, ironically, totally ignored by the beast, who sought to seek vengeance on its imprisonment and consume as much as it could.

It is unknown what demon it is meant to be, yet, given the film's mention of Lot and the city of Sodom, it is probably meant to be Azazel, a fallen angel and collector of souls who is an agent of the Devil and who all fear.





  • Despite being the secondary antagonist of the film, the Demon is far more dangerous than Mok.
