Morchok is a minor antagonist of the online game World of Warcraft.
Morchok was once a passive guardian of Therazane, but eventually fell under Deathwing's sway. He is one of the few remaining Earth Giants to still remain loyal to Deathwing and the Twilight's Hammer after the war which destroyed most of the Destroyer's forces in the short time it was waged.
Morchok was given the assignment of tearing Wyrmrest Temple to the ground so that the Dragon Aspects and their allies would be assured a defeat. Unfortunately, as he was tearing down the front wall of the temple, he was attacked by an army of heroes and adventurers. After a long-fought battled, Morchok fell and Deathwing's front lines were defeated.
