Meglos (TV story)

Synopsis
The Doctor is invited to visit the planet Tigella by its leader, Zastor, who has become concerned about disputes between his people's two opposing factions, the religious Deons and the scientist Savants.

The TARDIS is intercepted by the megalomaniacal xerophyte Meglos, last survivor of the planet Zolfa-Thura, and trapped in a chronic hysteresis - a time loop - but the Doctor and Romana manage to free it.

Meglos, using the body of a kidnapped Earthling, transforms himself into a duplicate of the Doctor and steals the Tigellans' power source - a mysterious dodecahedron. He plans to use this to power an apocalyptic device with which he intends to destroy Tigella.

The Doctor, although hindered by the activities of a group of Gaztak mercenaries hired by Meglos, ultimately brings about the xerophyte's destruction by tampering with the dodecahedron's controlling computers.

Plot
The Doctor is mistaken for Meglos who looks exactly like the Doctor. The Doctor learns that Meglos plans to destroy the planet, and only the Doctor can stop him.

Story notes

 * Jacqueline Hill previously played Barbara Wright.
 * The working titles for Meglos were: The Golden Pentangle, The Golden Pentagram, The Golden Star, The Last Sol-Fataran and The Last Zolfa-Thuran.
 * The end title's music of each of the episodes has been reduced by 2 or 1 octaves.
 * With the obvious exceptions of season one's The Edge of Destruction and single episode stories (Season Three's Mission to the Unknown), the The Five Doctors, 1996 TV movie and the new BBC Wales series), this is the only story in the series' history in which all the credited cast members appear in all the episodes.
 * The sound effect created for the approach of the Fendahl in Image of the Fendahl is re-used as background atmosphere for the Tigellan jungle.
 * The scenes set on the surface of Zolfa-Thura were realised by way of a new effects technique referred to as scene-sync - a development of the established CSO process. This involved two cameras being electronically synchronised to follow identical movements so that they could be made to track in unison and maintain the composite image (created in the usual way), whereas previously CSO shots had almost invariably been static.
 * Bill Fraser agreed to play Grugger only if he could kick K9.

 * Part 1 - 5.0 million viewers

Novelisation and its audiobook

 * Main article: Meglos (novelisation)


 * Novelised by Terrance Dicks in 1983.
 * The novel answers the question of how Meglos's species would be able to advance technologically as immobile cacti by their ability to take over the minds of other beings, implying that, despite what was shown, they are able to do it without technological adjuncts.
 * Also explained is why Meglos asked for an Earthling to use as a Host body rather than a (much closer) Tigellan? The novelization claims that Meglos considers Earthlings to be more "malleable".
