TERROR OF THE ZYGONS
30th August – 20th September 1975
You can’t rule the world in hiding. You’ve got to come out onto the balcony sometimes and wave a tentacle.
The Doctor to Broton, the Zygon commander, episode 4
Reunited at last with the TARDIS, the Doctor, Sarah and Harry go back to present day Scotland, responding to a summons from the Brigadier to investigate the sinking of several North Sea oil rigs.
The rigs are being sunk by the Skarasen, a huge creature, part lizard, part cyborg that has, for centuries, served the crew of a stranded spacecraft piloted by embryo-shaped alien Zygons, moored underwater close to the ancestral home of the Duke of Forgill. Discovering that his home planet has recently been destroyed, Broton (John Woodnutt), leader of these Zygon bipeds, has become tired of hiding from humanity. Armed with the invincible Skarasen, he now intends to attack Earth’s leaders as phase one of a plan to take control of this planet.
Assisted by soldiers from the Brigadier’s United Nations Intelligence Taskforce (UNIT) the Doctor pursues the Zygons from Scotland to the banks of the Thames. The Zygons are eventually destroyed but the monster, rendered harmless by the death of its masters, is free to swim back to Loch Ness, the only home it knows.
