Magma Beast

Magma Beasts are large, humanoid predators native to the deeper caves of Androzani Minor. They look 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. Though they frequently encountered Sharaz Jek's androids, they didn't bother them since they only ate meat. (DW: The Caves of Androzani)
