Ood Operations

Ood Operations (AKA the "Double O") was a Human run corporation that were selling the Ood into slavery in 4126. The company was shut down when Ood infected with the Red-eye virus revolted and began to kill the staff with their translation orbs. It was revealed that the company had made the Ood subservient by removing their secondary external brains and by placing a circle of energy pylons around the Ood Hive Mind which worked as a telepathic inhibitor. Halpem's personal Ood Sigma had been dosing Halpem with a solution mixed with hair tonic that transformed him into an Ood. The Doctor and Donna shut down the telepathic inhibitor and restored the Ood's ability to 'sing' telepathically again. The Ood song called out for all Ood that were off-planet to return home. With the Ood free and most of the company's staff or fleeing off-planet the company shut down allowing the Ood too be free again.
