Blue Daleks had several different connotations throughout Dalek history, typically holding a rank superior to normal Dalek drones. It sometimes indicated a normal officer rank, but also had a track record of being associated with time travel experts.


During the 2150s Dalek invasion of Earth, a at least one Blue Chrono-Dalek was at the disposal of the Red Dalek. The Blue Chrono-Dalek was capable of acting alone and following the Daleks' enemy through time; (TV: Susan and the Daleks) time travel at that point in Dalek history was in its infancy, with its existence being beyond the understanding of ordinary drones. (AUDIO: The Mutant Phase)

Some of the Humanised Daleks who lived in Alpha's colony on the planet Kyrol following the Dalek Civil War were Blue Daleks. (COMIC: Children of the Revolution)

The Eighth Doctor told Sam Jones that in the Dalek Prime's Empire, Blue Daleks were Daleks bred to be non-commissioned officers. Slightly smarter than the grey Warrior Daleks but without the higher-ranking Red Daleks, Black Daleks and Gold Daleks' levels of autonomy, they served as the equivalent of sergeants and corporals. The Eighth Doctor told Sam this when she asked about the differently coloured Daleks milling about their city, some of which were blue.

During a trial of Davros conducted to root out traitors who sided with him, Blue and Red Daleks filled the room back to the walls behind the higher ranking Daleks. In the ensuing war a Blue Dalek in Davros' resistance was in command of a detail that was setting up bombs in the lift shafts to destabilise the structure of the city's control centre building. Under fire from the Dalek Prime's forces he continued to work on priming the first bomb but as the Daleks beside him were killed he made the decision to abort the countdown and detonate the bombs. The structure was weakened but remained intact. (PROSE: War of the Daleks)

The Dalek Time Controller had a blue casing. (AUDIO: To the Death, X and the Daleks)

During the Last Great Time War, the Dalek members of the Eternity Circle were mostly blue, with silver domes and globes. Other Daleks present at the Daleks' temporary base in the city of Andor on Moldox were silver with blue domes. (PROSE: Engines of War) During the war, the Daleks of the Dalek Scientific Division were denoted by blue domes and sense globes. (AUDIO: A Thing of Guile)

After the Time War, Strategist Daleks of the New Dalek Paradigm were identified by their blue casings. (TV: Victory of the Daleks) As a result of the many failures of the original New Paradigm Supreme, this design of Blue Dalek was eventually retired, save for the original Strategist. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

The reconstructed casing of one Dalek reconnaissance scout, though heavily rusted, bore faded light blue paint on its dome, grating section, weapons platform and sense globes. (TV: Resolution)
