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 the drone on the Dalek Time Squad.

After going to the Dark Times, the Dalek drone 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; the very same message that made the Emperor send the Time Squad back to the Dark Times.
