Baron Harkennen was the villain of Dune. He was one of the richest members of Landsrader and the mortal enemy of the Atreides. Baron Harkonnen was a fat character, and he needed a Levitation Belt to move. In the movie, the reason Baron Harkonnen was not poisoned to death was because he flew above the poisonous gas. He was a cold and cruel character who had been trying to destroy House Atreides. The actor Stehran Skarsgaard spent several hours to complete the appearance of Baron Harkonnen. To make it easier to move around, he also had a special floating belt tied to his body.

All in all, Baron Harkonnen was an evil and cunning character who had waged a life-and-death struggle against the Atreides.
