Scotus

Doctor Scotus was an Earth physician.

During his time as a veteranarian, he discovered an alien tapeworm in a cow near Cardiff. It infected him, then found it induced ravenous hunger and weight loss in its host. After experimentation he found out how to control and kill it. He used the eggs as part of a diet plan for his patients.

However, his control over their life-cycle using herbs was not absolute. He also did not know until after he had prescribed his weight loss pill to a number of patients that the tapeworm could cause psychosis if it grew too large. Torchwood Three were able to give him the drug he had developed to kill the tapeworms. Scotus' parasite, though, was so integrated with its host that he died as well.

Scotus was tall and thin. He wore a black suit with a high, round collar and a white, uncreased shirt. His blond hair was brushed back over his forehead, although there were some stray hairs which waved gently. He had a deep and confident voice, with a veneer of good fellowship. To Rhys Williams, he looked to be about 40, though he had a healthy face and could have been much older. He had hot, dry hands. (PROSE: Slow Decay)
