Dalek 1 (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 blocked the Doctor and Yasmin Khan's attempt to escape from another Executioner. Revealing to the Doctor that the time loops were caused by her TARDIS rather than the Daleks, the Dalek informed her that she was to be executed for the destruction of the Dalek War Fleet and refused to acknowledge the Doctor's explanation that the Sontarans were responsible before exterminating her and Yaz.
