Talos

Talos was a monstrous bronze man with gigantic stature who guarded the island of Crete in Greek mythology.

Description
Talos was entirely made of bronze, though he has a single vein within his body. The vein connected from ankle to neck, and had the blood of gods, ichor, coursing inside. A nail in Talos' ankle prevented the ichor from flowing out.

As his entire body was formed out of metal, there was no need for conventional armor for Talos. He did have a helmet which resembled that of ancient hoplites. When Talos moved, his joints would squeak and creak.

History
There are two different explanations for Talos' existence. First and most common is that he was an automaton constructed by Hephaestus to protect the island of Crete.

Another version is that Talos was last remaining member of ancient race of brass men that were warlike and violent humans from different age. In this version Talos was a gift from Zeus when he wanted to impress Europa, the princess of Crete.

Regardless of version, Talos was to move around the shores of Crete three times a day and repel invaders.

Talos died at the hands of Medeia, who bewitched Talos to pluck out the nail from his ankle.

Abilities
Supernatural Strength - With his immense strength he would hurl boulders at ships trying to approach Crete. With just one swipe of his arms Talos could destroy infantry formations.

Immolation - Talos was able to heat his own body so that it would burn everything it touched.

Impervious - With whole body constructed out of metal, it is impossible to injure Talos by conventional means.
