C'Thraxxi (singular C'Thrax) are monstrous warbringers far larger and more resilient than other lesser n'raqi. They seem to usually serve as protectors within places of great importance to the Old Gods, and as commanders and generals of the Old Gods' forces. The C'Thrax Warlord Zon'ozz was one of the two faceless generals that led the assault on Wyrmrest Temple during the final battle against Deathwing.
C'Thraxxi possess arthropod-like features, along with great strength and brutal intellect. Their dark powers can drive even titan-forged to madness. Even after what mortals might consider death, C'Thraxxi can still slowly regain their energy and return to life through external help. The Twilight's Hammer made one such attempt to awaken Zakajz, and trolls have in the past succeeded to do so via blood rituals such as those that awakened Kith'ix and Mythrax.
