Red Dalek Leader

When the First Doctor stole the Time Destructor's Taranium core and replaced it with a fake, a Red Dalek was sent by the Dalek Prime to Kembel with a Dalek time machine. The Red Dalek was placed in command of a squad of Daleks tasked with pursuing the Doctor's TARDIS and retrieving the core. Mavic Chen answered to the Red Dalek when they landed in ancient Egypt. Although the squad successfully retrieved the Taranium core, the Red Dalek was destroyed by the Egyptians who bombarded it with rocks. (PROSE: The Mutation of Time)

Behind the scenes
While there is no apparent difference between this Dalek and the others under its command in The Daleks' Master Plan, the fact that the serial is in black and white allowed John Peel the freedom to turn it into a Red Dalek for the novelisation, making it the first Red Dalek to appear outside of comics. Its death did not occur on-screen, although one Dalek was rendered immobile as Egyptians stacked rocks around its base. Peel would include another Red Dalek in his novelisation of The Evil of the Daleks.
