Medic (The Invisible Enemy)
From Tardis Wiki, the free Doctor Who reference
A medic at the Bi-Al Foundation in 5000 was taken over by the Swarm.
When the Nucleus was taken out of the Fourth Doctor's body, the medic, along with Lowe and an opthalmologist, took it to Titan Base. He later attempted to kill the Doctor and Leela, but was shot and killed by K9 Mark I. (TV: The Invisible Enemy)
