Tim (Didn't You Kill My Mother?)
Tim was a sentient Dalek time machine built by the Cult of Skaro on their homeworld during the Last Great Time War, in order to infiltrate the TARDISes on Gallifrey.
Like TARDISes, he was dimensionally transcendental, and his control room strongly resembled theirs. He could take on a humanoid form within his own dimensions, with a personality and motives of his own.
At some point, he decided that his creators the Daleks should be wiped out. (AUDIO: Didn't You Kill My Mother? [+]Loading...["Didn't You Kill My Mother? (audio story)"])
Biography
Tim was created on Skaro during the Time War by the Cult of Skaro, being designed to infiltrate the ranks of TARDISes.
After the Time War, he met Arabella Hendricks, who recognised him (from later on in his timeline) as her consultant. Tim helped her develop the Surge as a counter to the threat of the New Dalek Paradigm, however realised it would not be refined and distributed adequately in time for the inevitable invasion. Tim devised a plan to self-destruct to alter history to enable the Surge to be given to Hendricks much earlier, however was unable to instigate the plan as he could not self-destruct without the order of a commander.

Meeting the Doctor
Though he believed that the Doctor never actually fought in the Time War, due to the Doctor erasing records about himself, Tim heard many legends about him from Earth so sought out the Eleventh Doctor to be his commander.
Tim brought Mrs Hendricks, Valarie Lockwood and the Doctor inside him, dressed up as an office, removed some of their memories, and pretended to be an impartial arbiter alongside "Mr Doctor". He tried to force the Doctor to make a choice between the two on who was right, as a test to see if the Doctor would carry out his plan. The Doctor refused to make the choice however.
After explaining his true identity to the Doctor and restoring everyone's memories, Tim explained his plan to stop the Daleks however the Doctor refused to carry it out. After Valarie and Hendricks drew his attention Tim turned on Hendricks, erasing her, which the Doctor used as a opportunity to rig parts of Tim’s interior to destruct. This distraction enabled him and Valarie to escape Tim in the TARDIS. (AUDIO: Didn't You Kill My Mother? [+]Loading...["Didn't You Kill My Mother? (audio story)"])
