Gargonnath the Corruptor is a massive, vile pit lord in service of the Burning Legion. One of the largest and most deadly of his kind, he served as replacement for Mannoroth following his death at the hands of Grommash Hellscream. After the former event, the gigantic demon was hand-picked by Tyrant Vandaala, to command her forces as they invaded Draenor and later, the invasion of Azeroth. One of Gargonnath's top agents is the nathrezim infiltrator known as Morgul'zum, who has spied on the Alliance for years.
