Dalek 3 (Eve of the Daleks)

A bronze Dalek was one of five Dalek Executioners which were dispatched in an ill-fated attempt to execute the Thirteenth Doctor.

In one time loop, it pursued Nick to his subsection of ELF Storage, where he used his exes' belongings as a barrier. The Dalek then destroyed these items with Nick thanking him for the "therapy". When the Dalek asked for an explanation, Nick replied "ex... terminated", upon which the Dalek exterminated Nick without saying a word.

Ultimately, after the last time reset, the Doctor destroyed ELF Storage and the Dalek Executioners with it before they could exterminate anyone. (TV: Eve of the Daleks)
