RAM

Ram was one half of the computer program Prog/Ram, modified Sontaran software used by the Minister of War. Such modifications split the original intelligence into two, Ram more closely resembling the original, though with a pronounced exasperation at his counterpart.

Biography
Ram’s voice could be heard in the Sontaran Command Facility in the form of his initial software, lacking the emotion of their altered system, though the 14th Doctor still recognised their voice based on their chronologically previous meeting. (AUDIO: The Rutan Stowaway; Conquest Of Sontar). Upon transportation to the Minister of War’s observation room, Ram helped the Minister of War scan the Doctor’s brain. Once a Rutan EMP was deployed by Jonski, wiping out the planet’s electronic signals, the Minister instructed the intelligence to relocate to Sontar’s moon, Ansoator. (AUDIO: Conquest Of Sontar)

Ram would go on to kidnap humans from Earth using buses, using them as test subjects under the Minister of War’s directive and converting them into Shadow Hosts. They would communicate with the buses and their Driver on recruitment runs. They assisted in operating the program that attempted to convert Jason Whittaker, though this backfired as Damien Drake managed to halt the process. Any resistance by Ram was thwarted by Prog, who activated the emergency protocols, destroying the facility and Ram along with it. (AUDIO: Out Of Service)

Ram’s consciousness was restored by the time of the Minister of War’s invasion, free of Prog, running the spaceships acting as shadow transmitters. While generally passive as the Doctor disabled each ship, Ram took a more active role on one ship, preventing the Doctor from gaining access. In response, the Doctor fiddled with his software, causing Prog to reemerge and Ram to self-destruct. (AUDIO: Eternal War).
