The Pyrovile

Pyroviles were humanoids with a rock-based form with a magma interior. They were able to shoot flames out of their mouths, which could easily turn a Human to ashes in seconds. They could be killed by sufficient quantities of water, their internal heat being snuffed out and their bodies solidifying. They were tall beings, reaching up to about 10 metres in height and resembling oversized Roman soldiers. Pyroviles came in two varieties - a shorter, easily-destroyed "Foot Soldier" and more advanced, fully grown Pyroviles, which could reach over twice this height.
