Supreme Dalek (The Wedding of River Song)

A white Supreme Dalek was heavily damaged and imprisoned when it was encountered by the Eleventh Doctor, who taunted it and then took all the information it had on the Silence from its data core. The Dalek reacted with panic when it was confronted by the Doctor, but because it was too badly damaged and on its side, it couldn't do anything to stop the Doctor download information from its data-core.

Having acquired what he came for, the Doctor cut off the Dalek eyestalk and left, leaving the Supreme for dead. (TV: The Wedding of River Song)

A Dalek without its eyestalk and the same battle damages was on the Dalek Asylum when it was destroyed. (TV: Asylum of the Daleks)
