Count Glossu Rabban

Glossu Rabban was a minor villain of the Dune universe. Due to his penchant for sadism and cruelty without the intelligence of other members of the House of Harkonnen, he was given the nickname "The Beast." Rabban was the elder brother of Feyd-Rautha, and the nephew of Baron Vladimir Harkonnen.

In the aftermath of the Harkonnen attack on the House of Atreides on Arrakis that nearly destroyed the House, Rabban was left in charge of Arrakis by his uncle. Harkonnen gave him orders to squeeze the populace, and to set new lows in cruelty and depraved behavior. Harkonnen's intention was that when the people of Arrakis were crushed enough that he would send Feyd to save the people of Arrakis, and become a hero to the people there.

What none of the Harkonnen leaders anticipated was that Duke Leto's consort Lady Jessica and son Paul Atreides would survive and be taken in by the Freman natives of Arrakis. Paul would lead the Freman in a war against the Harkonnen which brought spice production to a standstill. Fearing for his life, Rabban never told his uncle of the difficulties he was having while trying to stop the Freman.

In an attack on the Harkonnen the Freman got ahold of The Beast. The Beast met his end then, with his head being delivered to the Emperor.
