Magma Beast

Magma Beasts are large, humanoid predators native to the deeper caves of Androzani Minor.

They looked somewhat like a hybrid between dinosaurs and armadillos and had massive fanged heads, armour-covered bodies and a cape-like shell. Magma beasts came up to the higher caves when they were hungry, eating the soldiers from Androzani Major that were common in the area. They frequently encountered Sharaz Jek's androids, but didn't bother them since they only ate meat. (DW: The Caves of Androzani)
