Dalek (The Lights of Skaro)

This Dalek was one of the combatants of the Thal-Dalek battle, being defeated after the First Doctor, Ian, Barbara, Susan and the Thals stopped them from further irradiating Skaro. (TV: The Daleks)

However, this wasn't the Daleks' final end as some, including this one, survived. Operating a Dalek War Machine casing, this Dalek was dependant on an inductive feed of static electricity via the metal floors of the Dalek City, leaving it trapped within the settlement. Vince Foster, a journalist, made his way through a control room. He knew of the Daleks and explained to Varna about some of their workings. He was helping Varna protect her world from the Thals. He wanted to use the Daleks for his own ends, seeking an alliance with them, only to be exterminated by the Dalek he had revived. When the Dalek turned its attention to Varna, who identified as an ideal Kaled, and thus did not want suffering. Initially believing the Daleks to be Thal inventions, she was horrified to discover the Dalek mutant within the Dalek with it exterminating her soon after.

Later, Bernice and the Seventh Doctor showed the Dalek its future self. Its older counterpart designated that it no longer sought desire to leave its travel machine much to the disgust of its younger self. Two versions of the same Dalek opened fire and killed each other creating a paradox, restoring the time stream. (AUDIO: The Lights of Skaro)
