The Baron Vladimir Harkonnen is a fictional character and antagonist from the Dune universe created by Frank Herbert. He is primarily featured in the 1965 novel Dune and is also a prominent character in the Prelude to Dune prequel trilogy (1999-2001) by Brian Herbert and Kevin J. Anderson. The character is brought back as a ghola in the Herbert/Anderson sequel which conclude the original series, Hunters of Dune (2006) and Sandworms of Dune (2007).

"Appendix IV: The Almanak en-Ashraf (Selected Excerpts of the Noble Houses)" in Dune says of him (in part):

VLADIMIR HARKONNEN (10,110-10,193) Commonly referred to as Baron Harkonnen, his title is officially Siridar (planetary governor) Baron. Vladimir Harkonnen is the direct-line male descendant of the Bashar Abulurd Harkonnen who was banished for cowardice after the Battle of Corrin. The return of House Harkonnen to power generally is ascribed to adroit manipulation of the whale fur market and later consolidation with melange wealth from Arrakis.

In Dune, Herbert notes that the Baron possesses a "basso voice" and is so "grossly and immensely fat" that he requires anti-gravity devices known as suspensor to support his weight. It is implied by Margot Fenring that the Baron has allowed himself to become obese.

Baron Vladimir Harkonnen has not been a contender in any CBUB matches.
