Primord

From Tardis Wiki, the free Doctor Who reference

The Primords were savage humanoids created by the Stahlman's Ooze.

The Primords were originally humans who had been infected by the "Stahlman's Ooze". This infection could be spread simply by touch. The Primords looked like hairy humans with green skin and sharp teeth and claws. They were much tougher then a normal Human, being able to survive several gunshots. Their intelligence decreased as they transformed and they started to lose concentration in their surroundings, although they still had some degree of intelligence and were able to organize themselves in attacking surviving humans. Primords radiated immense amounts of heat and could only survive in hot temperatures, with cold temperatures being deadly.

Primords were found both in the regular universe and the alternate dimension. (DW: Inferno)

The name Primord comes from promotional and reference material. It does not occur in the story itself at all.
