Baron Vladimir Harkonnen is a ruthless, cruel, and unparalleled conspirator and the head of House Harkonnen. He is among the wealthiest members of the Landsraad due to House Harkonnen's spice melange activities on Arrakis, and Duke Leto Atreides' sworn enemy.
Vladimir rules over his house with an iron fist from House Harkonnen's imperial seat on Geidi Prime.
