Morrison (The Time Warrior)

Professor Morris was a scientist in the 20th century. He worked at a top secret research facility to produce space hardware.

When scientist began disappearing, he and the other scientists were confined by UNIT to the facility for their safety. He was kidnapped by the Sontaran Linx and brought to the Middle Ages, who hypnotized him to help repear his spaceship.

When Professor Rubeish snapped them out of the hypnosis, he returned Morris and all the others to the 20th century. (TV: The Time Warrior)
