"Piter de Vries is a major antagonist in Frank Herbert's novel Dune, as well as the lead henchman and adviser to the true villain of the story, Baron Vladimir Harkonnen. As a Mentat, he primarily serves as the evil genius of the Baron's villainous hierarchy, using his immense mental powers to process the data required for House Harkonnen to enact its schemes upon the other Great Houses. However, as a Twisted Mentat produced by the infamous Bene Tleilaxu, de Vries is also an amoral psychopath with an extremely sadistic bent, and is not afraid to bloody his hands over the course of his duties. He is portrayed by Brad Dourif in the 1984 film and Jan Unger in the 2000 Sci-Fi Channel (now SyFy) miniseries."@en . "Dune"@en . "Right Hand"@en . .
