Elite Guard Dalek (The Magician's Apprentice)
From Tardis Wiki, the free Doctor Who reference
An Elite Guard Dalek was among the many types of Daleks inside the Dalek City at the time of the Twelfth Doctor's visit. It greatly resembled the Imperial Guard of the Dalek Civil War, but modified with a blue eye lens as seen on bronze Daleks. (TV: The Magician's Apprentice/The Witch's Familiar)
