Red Dalek

Before the Last Great Time War, Red Daleks were bred for intermediate roles between the less intelligent Blue Daleks and the Daleks that served as their immediate superiors, the Black Daleks. Unlike Blue Daleks, they were capable of independent thought, allowing some measure of independent action. (PROSE: War of the Daleks)

Like Black Daleks, they were capable of holding the rank of Supreme Controller. (AUDIO: "Death to the Daleks!")

Early history
The earliest known Red Dalek was in charge of the construction of the Sky Seven Space Station when the Mechanoids made their opening volleys in their war with the Daleks. The Red Dalek Leader spared the life of a raving mad Dalek because he correctly believed it was tied to the detected transmissions of alien signals. He located and exposed a camouflaged Mechanoid Interceptor and destroyed it before it could flee. Two more Interceptors arrived, both protected by force fields. He ordered the Daleks to retreat but his Dalek flying saucer was melted as he screamed about the heat and the light. (COMIC: Eve of War)

Following the destruction of Skardal, a Red Dalek was with the Dalek Emperor as he watched the Terrorkons run rampant. The Red Dalek suggested they simply kill off the Terrorkons, but the Emperor told him the Terrorkons were part of the city's defence system and simply had to be constantly outwitted. When a lone Terrorkon stole a missile powerful enough to destroy the city, the Emperor took the Red Dalek with him to stop it. Reaching the caves in the mountains through the pipe systems, they found the missile activated and close to detonation. The Red Dalek defused the missile. (COMIC: The Terrorkon Harvest)

The Emperor called a meeting with the Black Dalek and a Red Dalek when the presence of the One in a Million Dalek threatened to cause a civil war. (COMIC: Shadow of Humanity)

A Red Dalek was aboard the Emperor's ship when the Daleks first travelled into the Sol System ahead of the invasion. (COMIC: Return of the Elders)

Later history
In the late 40th century, a Red Dalek led the assault on the Space Security Service compound on M5. (AUDIO: The Destroyers)

There was a squadron of Daleks named the Red Extra-Galactic Squadron. When its commander denounced the Emperor for military failures and demanded a new Dalek take its place, the Black Dalek obliterated the whole squadron. (COMIC: The Secret of the Emperor)

In the year 4000 when the Daleks made an alliance with the Outer Galaxies and planned to destroy the Solar System with the Time Destructor, the First Doctor interfered and replaced the Time Destructor's Taranium core with a fake one. Upon learning of the Doctor's deception, the Daleks contacted Skaro and the Dalek Prime sent a Red Dalek to Kembel in a Dalek time machine. They pursued the Doctor's TARDIS to ancient Egypt and successfully recovered the core but the Red Dalek did not survive the mission, being destroyed by rocks in a fight between the Egyptians. (PROSE: The Mutation of Time)

The failure of the Time Destructor plan led directly to the Great War which lasted over a millennium. The Emperor tried to win the wars by blackmailing the Second Doctor into discovering the Human Factor and, by extension, the Dalek Factor. A Red Dalek, acting as an emissary for the Supreme Council, oversaw the experiment on Earth in 1866 and returned to Skaro with the other Daleks upon its completion. Other Red Daleks were also present in the Dalek City at the time but the Doctor believed them all destroyed along with the rest of their race when he ignited a civil war against the Emperor's Black Daleks and the rebelling Daleks reconditioned with the Human Factor. (PROSE: The Evil of the Daleks)

After Commander Don Morais and Zec were lured into a trap and transported to Skaro, a Red Dalek tasked them with finding a stratum of the mineral Doranium beneath the planet's surface. (COMIC: The Dalek Trap)

A Red Dalek, leader of the Thaleks, tortured Jesic and Murgat. The word exterminate told by Jesic caused the entire facility to crumble. The Red Dalek and the Thal-Daleks were killed by the collapsing. (AUDIO: Brotherhood of the Daleks)

Many Red Daleks, among other ranks, were present on Skaro shortly after the Imperial-Renegade Dalek Civil War when the Dalek Prime placed Davros on trial. Like all other ranks with the exception of the Dalek Prime's elite Gold Daleks, the Red Daleks were divided in loyalties - some were loyal to the Dalek Prime while others supported Davros. Davros's supporters were believed to have been wiped out in a brief but devastating battle which erupted when a Black Dalek supporting Davros attempted to assassinate the Dalek Prime. (PROSE: War of the Daleks)

During the Dalek Empire's invasion of Mutter's Spiral a Red Dalek was Supreme Controller of the sector of the planet Celatron. The Dalek Supreme was its direct superior. (AUDIO: "Death to the Daleks!")

Red Daleks and Black Daleks, identical in shape to the basic bronze Daleks, had occupied the Starbane when the Twelfth Doctor and Lumpy arrived with the intention of destroying the vessel along with the Orb of Fates. A Red Dalek explained to the Doctor that Lumpy's capture by the Cybermen was engineered so that the Doctor would hand over the Orb of Fates and the Starbane to the Daleks. All Red Daleks were killed when the Starbane exploded. (GAME: The Doctor and the Dalek)

Shift in the timelines
Red Daleks were among the dormant army in the Fifth Galaxy. The army was awoken by the Dalek Prime Strategist, (WC: The Sentinel of the Fifth Galaxy) belonging to a version of the Restoration Empire that did not fight the Time War (COMIC: Defender of the Daleks) which had been created by temporal fluctuations in the Dark Times. (PROSE: The Guide to the Dark Times) The Red Daleks were compromised by the Entity, the very enemy the Strategist had awoken the army to fight against, and turned against the Dalek Empire. (WC: The Sentinel of the Fifth Galaxy)

Other red Daleks
Numerous Daleks have been red, unrelated to this caste system. Zeg's casing changed colour during an accident in an engineering lab. (COMIC: Duel of the Daleks) Storm-Blast Daleks were red. (COMIC: City of the Daleks) Some Daleks were also covered with red lead to resist corrosion on planets with humid environments, like Venus. (PROSE: Red for Danger)

Among the Daleks of Azhra Korr, the First-Born, Alpha, had a red casing, although his role and his title were more like that of the Dalek Prime on Skaro. (COMIC: Children of the Revolution)

The Dalek force which captured various Earth naval vessels and conducted a raid on Sydney Harbour included a silver Dalek with a red dome as the second-in-command. (COMIC: *Sub Zero)

Towards the end of the Last Great Time War, the casing of the Eternity Circle's Predator Dalek was vermillion with black globes. The 'Spider' variant of the Skaro Degradations had a similar colour scheme. (PROSE: Engines of War)

A race of Daleks newly created from Davros' cells after the Time War were led by the red Supreme Dalek, who also was the highest ranking among his Daleks. (TV: The Stolen Earth) The Supreme Dalek was destroyed by Jack Harkness. (TV: Journey's End) An identical Supreme Dalek led the Daleks in the reconstructed Dalek City on Skaro when, with Davros's help, they sought to become Dalek/Time Lord hybrids. It was still present in the city when regenerated decomposing Dalek mutants attacked the place. (TV: The Magician's Apprentice/The Witch's Familiar)

In the New Dalek Paradigm, the red Drone Daleks were initially the lowest ranked. (TV: Victory of the Daleks) Later, standard Dalek soldiers were once again identified by a smaller bronze casing and the red drones were given a higher status. (TV: Asylum of the Daleks)

Merchandise

 * Dapol, which produced a range of toys based on the classic series of Doctor Who, released several original red Dalek variants which did not appear on-screen.
 * W008-5 was red with black details (eyepiece, neck grille, slats, manipulator arm, gunstick and sense globes).
 * W008-6 was red with silver details (eyepiece, neck grille, slats, manipulator arm, gunstick and sense globes).
 * W008-7 was red with gold details (eyepiece, neck grille, slats, manipulator arm, gunstick and sense globes).
 * W008-9 was designed similar to the Daleks' Invasion Earth 2150 A.D. Red Dalek but with a claw manipulator arm and a gunstick of different mould.
 * A "Millennium Dalek" (W008-M3) had a sparkly red body with a golden neck grille, slats and sense globes.

Other matters

 * Both Dr. Who and the Daleks and Daleks' Invasion Earth 2150 A.D., the remakes of The Daleks and The Dalek Invasion of Earth starring Peter Cushing as Dr. Who, feature a Red Dalek. In the first film, it is the second-in-command to the Black Dalek, and in the second film it appears to act as the Dalek saucer commander while the Black Dalek and Gold Dalek command the invasion. They were the first ever Red Daleks to be seen on colour film but the show itself would not feature a Red Dalek until The Stolen Earth in 2008.
 * As a pre-Time War rank, Red Daleks have never appeared on the TV series. The closest they came to this was being included in John Peel's novelisations of The Daleks' Master Plan and The Evil of the Daleks, the original serials of which were in black and white.
 * The Doctor and the Dalek featured Red Daleks in revived series media for the first time. The Supreme Dalek of the New Dalek Empire and initial drones of the New Dalek Paradigm held different ranks.
 * Red Daleks feature on the covers for The Dalek Outer Space Book, the DWM special release of The Dalek Chronicles, the novelisation The Mutation of Time and the Main Range audio story Brotherhood of the Daleks.
 * A Red Dalek with a hoverbout was seen on the loading page of a video game Dalek Attack.
 * The concept of a Red Dalek, at least for later fans and story writers, was based on a misunderstanding that some of the Black Daleks in 60s serials were red, due to the black and white film. This either originated with, or was compounded by the various annuals and comics depicting red-coloured Daleks. This was not resolved until colour set photos became available in the early 2000s.
 * In Dalek Hack, the player has the option to turn a Dalek's casing red, shaped identically to the bronze Dalek but matching the Drone Dalek of the New Dalek Paradigm.
