Dalek (The Lights of Skaro)

This Dalek was one of the combatants of the Thal-Dalek War that died after the First Doctor, Ian, Barbara, Susan and the Thals stopped them from exploding the Neutron bomb. (TV: The Daleks)

However, this wasn't the Daleks' final end as some of the Daleks including this one survived. It was one of the old Dalek designs that could only travel on electricity via metal floors as it could not leave its city. 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. He wanted to form an alliance with the Daleks, but the idiotic man was exterminated by the Dalek he had revived. Then the Dalek turned its attention to Varna. She was identified as a Kaled. She said that the Kaleds would not want suffering. She was an ideal Kaled, but the Dalek learned that they were evolved from the Kaleds, so it exterminated her too.

Later, Bernice and the Seventh Doctor showed the Dalek its future self. Its older counderpart designated that it no longer sought desire to leave its travel machine much to the disgust of its younger self. The Dalek than killed its future self before being destroyed itself.
