Dalek Executioner
From Tardis Wiki, the free Doctor Who reference
Dalek Executioners were a new variant form of Dalek introduced at the Emperor of the Restoration's behest to his Restoration Empire following the end of the Imperial-Renegade Dalek Civil War.
They were the new designation of the Daleks who had previously driven Special Weapons Dalek casings, which they were ordered to swap out for black casings more similar to classic Dalek travel machines, albeit with unique manipulator arms and colour schemes. (PROSE: The Restoration Empire) One insane, sadistic Executioner was assigned to the Dalek Time Squad. (PROSE: The Guide to the Dark Times)
