You would imagine that in an Interstellar Imperium that stretches thousands of light years, there would at least be another sentient alien race but no, that’s not the case with Dune, there are however huge variations of humanity, some are bred differently, some have been hybridized, some have evolved with the use of Spice mélange while others have adopted a more cyborg path. So here in this video, we will explore the human types, hybrids and evolved forms that have been noted in the dune saga, at least a few notable ones.
Mentats After the abolition of thinking computers or A.I after the deady Butlerian Jihad, humans were recruited and trained to be used as living bio computers.
The Bene Tleilax, also known as the Tleilaxu, were a secretive group of genetically altered humans who lived on the planet Tleilax
Sorceress – These are a naturally evolved group of humans that have managed to have telekinetic and telepathic abilities. They are the precursors to the Bene gesserit
Navigators are a type of artificially evolved humans belonging to the Spacing Guild. Through consuming and being exposed to large amounts of the spice Melange
A Face Dancer was a part of a genetically altered and enhanced race created by the Bene Tleilax but with a status below their Tleilaxu Masters.
A Cymek was a thinking machine that was once human but had been converted into a cyborg, with a robotic body controlled by a preserved human brain.
hybrids called the Futars were a human/feline mix created by the Bene Tleilax
Harkonnen Pet – Seen only in the recent dune part one movie adaptation, the spider creature with human features is most likely a hybrid created by the Bene tleilax for the harkonnens
Axolotl Tanks Although appearing as machinery or equipment, the axolotl tanks were in fact females of the Bene Tleilax, transformed into a reproductive piece of machine
These Phibians are a hybrid humanoid subrace created through genetic engineering, mentioned in Chapterhouse: Dune.
These are members of the Atreides bloodline after Leto the first which had been mixed and monitored for millennia by the Bene gesserit under a breeding programme that would bring forth a Kwizatz Haderach.
