Medic (The Invisible Enemy)

A medic was a member of the Bi-Al Foundation in 5000. He was taken over by the Swarm. When the Nucleus was taken out of the Fourth Doctor's body, he, along with Lowe and an opthalmologist, escorted it to Titan Base. He later attempted to shoot and kill the Doctor and Leela, but was shot and killed by K9. (TV: The Invisible Enemy)
