Dalek (The Last Message)

A Dalek drone of the Restoration Empire was the instigator of the bootstrap paradox of the Empire's involvement in the Kotturuh crisis. The drone was in operation on Skaro when the Emperor of the Restoration received a message from the drone's future self, prompting the Emperor to put this Drone on the Dalek Time Squad.

After going to the Dark Times, this Dalek was left broken and drifting through space for many millennia, where it eventually partially repaired itself through sheer determination. Thinking itself the last survivor, it transmitted a warning to the universe about the Tenth Doctor. (PROSE: The Last Message)

Behind the scenes
The Dalek attempted to broadcast its warning about the Doctor using the hollow planet TG-88.3Ω. (NOTVALID: The Hollow Planet)

When it was broken and trying to repair itself, the Dalek was locked inside a cage in a corner of a spaceship about to explode. Its job was to stop anyone attempting to save the spaceship. It had a golden-glowing eyestalk lens rather than the regular blue vision of other Daleks. (NOTVALID: A Dalek Awakens)

The Dalek's final message, as it drifts through space, is shown in the Time Lord Victorious trailer.
