|Behind the Scenes|
|Universe||Ben 10 Universe|
Contemelias were a neutral 5th-dimensional race that traveled across the multiverse using a device called the Anihilaarg to create and destroy universes as experiments.
At some point in time the Contemelia died off. At least one of their vessels still flew across the multiverse labyrinth, as it passed into legends along with its tool/weapon.
Over time, many species started to predict the Contemelia as inter-dimensional beings who played practical jokes on the inhabitants of the universes they would visit. If the Contemelia did not like a particular universe, they would use the Anihilaarg to reduce it to nothingness.
Due to their body structure being 5th-dimensional, their true forms cannot be perceived by three-dimensional beings. Instead, they see a Contemelia as an animate projection of what holds the most emotional sway over them.
Meanwhile, genetometaphomorphic lifeforms such as Slimebiotes see a Contemelia as a mass of energy.
