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.
