Harry Slocum

Harry Slocum was a maintenance worker at the Inferno Project. While repairing a drill pipe, he became infected with Stahlman's Ooze and rapidly mutated into a Primord. His killing of a fellow worker soon afterwards caused UNIT to be brought in to investigate. Later, the creature that had been Slocum knocked out Bromley, infecting him, and increased the Project's power output to maximum. When he confronted the Doctor, Private Wyatt shot and killed him, but not before becoming infected himself. (DW: Inferno)
