After two defeats by the Tenth Doctor, Caan was thought to be the only Dalek remaining in existence. To create a new Dalek empire, he accomplished what was thought to be impossible: he breached the time-locked situation of the Last Great Time War and extracted Davros, the creator of the Daleks. This action cost Caan his mind, but allowed him to see into the future and manipulate timelines. (TV: The Stolen Earth, Journey's End) Caan was presumably killed, along with virtually the entire New Dalek Empire which he founded, when he betrayed his own kind. (TV: Journey's End)
