Planet Heck is essentially Hell in the
form of a planet.
This planet contains elevator music and villain music and countless tortures, as well as lawyers and demons, spikes and lava volcanoes and intense pain.
The planet is currently under the rule of Evil the Cat.
Evil the Cat has recently stated that he does not intend to destroy the Irken Empire. He instead wishes to become an ally of the Empire.
Evil the Cat used to want to destroy the universe until he learned of the Empire's campaign for conquest of the Universe.
Since then, Planet Heck has been guarded by the Empire.
