Not Yeti Friday - Tartarus

Tartarus is the main end-game baddie in the video game Halo 2 (2004).  He's Chieftain of the Jiralhanae, a race of bipedal, ape-like aliens from the planet Doisac (basically the Planet of the Apes) that humans call Brutes. They're the newest members of the Covenant Empire, a genocidal religious hegemony.

Tartarus wields the Fist of Rukt.
