Red Supreme Dalek (Liberation of the Daleks)

A fake Type E Supreme Dalek led a force of simulated Bronze Daleks as part of the 1966 Dalek invasion of Earth attraction at the Dalek Dome.

It was a Simulacrum version of Specimen Six Sigma, a real Dalek who had been captured and used by the Dome to power their simulation.

Biography
This Supreme Dalek believed itself to be real, but was actually a Simulacrum avatar used by the Dalek Dome company.

When the Fourteenth Doctor was led to the 1966 World Cup Final at Wembley Stadium by his TARDIS, the Supreme Dalek ordered his bronze Dalek drones to exterminate him before he could slip away. However, the Supreme was shocked to see that the extermination did nothing, and ordered it to be attempted multiple times.

After these efforts proved futile, the Supreme ordered the Doctor to be brought on board the saucer. Aboard, the Doctor hypothesised that the Daleks before him were actually fake clones, much to the rage of the Supreme. Desperate to prove it was a real Dalek, the Supreme ordered its Dalek Fleet to adopt Formation Red Icosahedron and destroy the Earth, much to the Doctor's horror.

Soon after, the Doctor was kidnapped from the Simulacrum, the Supreme took to contemplating what it had been told. After a while, it discovered that its universe was somehow breaking down, and in an effort to escape, took its chance to find out if the Doctor told the truth or not by forcing Georgy to open the TARDIS doors, and took off, finding itself in the Dalek Dome face to face with the Doctor and Georgette. The Doctor kept the Supreme talking until it and its two guard drones melted, unable to remain in the real universe. (COMIC: Liberation of the Daleks)

Appearance
The Supreme Dalek's casing was that of the Type E design, making it identical in appearance to a number of Supreme Daleks from elsewhere in the Daleks' timeline, such as a Dalek Supreme from the Second Dalek War, (AUDIO: Out of Time) a Dalek Supreme from the Last Great Time War, (COMIC: Ambush) the Supreme Dalek that led the New Dalek Empire onboard the Crucible, (TV: The Stolen Earth, Journey's End) and the Supreme Dalek that was the leader of the Dalek City on Skaro. (TV: The Magician's Apprentice/The Witch's Familiar) Said casing resembled that of a bronze Dalek, but coloured red with gold sense globes, in addition to a golden grating section that featured four large golden struts at compass points. Its red dome was adorned by three large luminosity dischargers instead of the standard pair that was featured on most other Daleks. (COMIC: Liberation of the Daleks)
