|Behind the Scenes|
Pyroxivors are a type of subterranean "cattle" that eat rocks in Ben 10.
Their skin is grey with brown patches on their back and tail. They have a brown horn coming out a patch on their forehead. They are always squinting with their small red eyes. because their natural habitat is in caves. They have two brown claws on each of their feet. They have rodent-like teeth in the middle of their mouth.
The Pyroxivors were introduced in Inferno. They were driven up from underground because Vulkanus made the earth warmer by bringing up heat from the Earth's core, as he was the rightful owner of the Earth (he bought it). The Pyroxivors returned to the ground when Vulkanus was defeated. Pyroxivors resemble large naked mole rats with a cow-like pattern. It is also revealed that they are also a source of food.
- There are Pyroxivors living in Undertown.
