“Tegan, why do you dislike me so much? You hardly know me?”.

Creepy agenda driven alien

Turlough (Mark Strickson), was first introduced in Mawdryn Undead – 1983, as a school student of ex-UNIT head, Lethbridge Stewart; who had retired from the Army and was teaching mathematics – at a private school.

Turlough was actually – an alien from the planet – Trion; who was under the control of the Black Guardian, who had a score to settle with the Fifth Doctor.

To say that Turlough was weird was an understatement. With his shock of bright red hair, pale skin, arched eyebrows and beady eyes. Tegan didn’t warm to him – and the Doctor never fully trusted him, either.

This was partly due to Turlough having been used as a pawn by the all-powerful entity; the Black Guardian – who wanted the Doctor dead, in the Black Guardian trilogyMawdryn Undead, Terminus & Enlightenment – 1983.

Turlough was controlled by means of a small flashing crystal, which also doubled as a communicator. However, he was not totally under the Black Guardian’s control and whenever he fought back against the impulses to kill, the Black Guardian punished Turlough – with physical and mental torture.

Turlough eventually freed himself, from the mind control and helped the Doctor defeat the Black Guardian, before joining the Tardis crew.

“What is it about Earth people, that makes them think a futile gesture is a noble one?” Turlough – Warriors Of The Deep

It was in Planet Of Fire – 1984, that Turlough finally revealed his origin to the Doctor – as being an exiled member of the Trion race. He also learned he was a “Chosen one”, due to a tattooed symbol on his arm.

When the people of planet Sarn were in danger – from an active volcano, the Doctor, Peri and Turlough helped them survive. Turlough decided to remain behind and help rebuild Sarn society.

A Trion rescue ship was on it’s way to meet Turlough and return him to Trion, where his previous crimes had been pardoned.
