Tarnok

Tarnok was a Glatorian who was employed by the Fire Tribe on Bara Magna, along with Sento. Tratus was his Agori partner in the arena matches. He wielded a Fire Mace and a Thornax Launcher.

One day while wandering the wastelands in the desert he was killed by Kakamu's gaseous antidermis form, so that the Makuta could take over Tarnok's body. Kakamu did this by stripping the body of flesh so that he could inhabit the metallic skeleton, and then add to it by magnetizing nearby pieces of metal to him. Grisly, right?

When Bara Magna was destroyed, and later recreated, Tarnok was one of the inhabitants who was not resurrected, because he had died before the planet's destruction.
