Glossu Rabban Harkonnen [10,132 A.G. - 10,193 A.G.], also known as the Beast, Mudir Nahya (Demon Ruler), and King Cobra by the Fremen, was the older nephew of Baron Vladimir Harkonnen, and the Count of Lankiveil.
Pardot Kynes accompanied him in a sandworm hunt; he wanted a trophy to take back to Giedi Prime. He had cropped brown hair and was broad-shouldered, deep-voiced, and short-tempered. He had icy pale blue eyes in a sunburned face.
On Giedi Prime he killed the parents of Duncan Idaho and participated to the hunt. Little Duncan evaded them twice and the last time he managed to leave off the planet.
Re-Established on DuneEdit
He inherited the Harkonnen penchant for sadism and cruelty, but not the cunning. He was best known for his tyrannical and vastly ineffective governance of Arrakis during the Harkonnen fiefdom of Arrakis, as well as during the insurgency of the Fremen led by Paul Muad'Dib. He earned the nickname "Beast" when he killed his father, Abulurd. The Baron planned to let Glossu rule the planet for a time so that when his favored nephew, Feyd-Rautha, took over, the new ruler would be welcomed as a hero.
Rabban was slain by the Fremen populace of Arrakeen, which he had brutalized many years.
