Although only briefly featured in Dune: Prophecy episode 3, Evgeny Harkonnen appears to be the most similar character to Baron Vladimir Harkonnen, played by Stellan Skarsgård in the Villeneuve films.

Baron Vladimir Harkonnen, the black-hearted baddie of Denis Villeneuve’s Dune, has a very particular look—as if birthed by one of H.R. Giger’s night terrors.
