Primord
The Primords were savage, furry humanoids created by Stahlman's ooze. They existed in both the Doctor's universe and a parallel universe visited by the Third Doctor.
Biology
Transformation
Primords were humans who had come into contact with either Stahlman's ooze or another infected human. The transformation occurred in stages. First, the infected area turned green, then spread across the entire body. The infected human's face developed bestial qualities and his teeth changed into fangs. Strength was drastically increased, as seen when one effortlessly bent the bars of its prison cell. Primords could generate heat in a way impossible for a human. Once fully transformed, they grew thick hair and partial hunchbacks. The transformation process took several hours under normal conditions, but in heightened temperatures, the full transformation could occur in a few seconds.
Behaviour
Primords banded together in groups, and instinctively sought to force humans into physical contact with the ooze so that they too would transform. Although a partially converted human could be killed by gunshots, once fully transformed into a Primord, they were immune. They could survive great heat, but found cold temperatures, such as those generated by fire extinguishers, to be fatal. Upon entering a room, they would sometimes need time to acclimatise to the temperature. (TV: Inferno)
History
The Doctor's universe
The first Primord was Harry Slocum, who came into contact with Stahlman's ooze while performing maintenance on the drill. It took him several hours to transform and even then it wasn't complete. In this time he accessed the power supply and almost caused an overload.
Stahlman himself was converted after he touched a fractured glass tube containing a sample of the ooze. His transformation became complete while he was in the drilling room. He was disabled by the Third Doctor and Greg Sutton with fire extinguishers. (TV: Inferno)
C19 preserved a small sample of the ooze in the Vault, injected it into a Dobermann Pinscher, and used it to create a mutated guard-dog known as the Stalker. (PROSE: The Scales of Injustice)
Parallel universe
The Third Doctor visited a parallel universe where the same drilling operation was occurring. The drilling released a significant amount of the ooze. The Primords which had already been created forced others into the ooze, so that they changed as well. Despite the efforts of the Third Doctor and a parallel Greg Sutton, the Primords infested the facility shortly before the planet was devastated by volcanic activity triggered by the drilling.

Behind the scenes
- The name "Primord" (from "primordial") comes from the closing credits, promotional and reference material to Inferno. It does not occur in the story itself at all.
