Dalek Commander (The Power of the Doctor)
From Tardis Wiki, the free Doctor Who reference
A bronze Dalek Commander led the Dalek forces who allied with the Spy Master as part of the Master's Dalek Plan. Although its appearance resembled that of a regular Dalek Drone, its deep voice, much like that of a Dalek Supreme and a similar Dalek Leader, signified its rank. (TV: The Power of the Doctor)
