Grommash Hellscream (Terry Notary)

Grommash "Grom" Hellscream was the chieftain of the Warsong clan, and best friend and chief advisor to Warchief Thrall. He was the first orc who drank the blood of Mannoroth the Destructor, thus binding the Horde to the Burning Legion — and he would eventually pay the ultimate price to free himself and his people from the curse.
