- You may be looking for the Renegade Daleks' Time Controller device.
The Dalek Time Controller was a Dalek from the far future which was created with an evolved mind that allowed him to perceive time in a more advanced manner than a standard Dalek. Consequently, the Dalek Time Controller was given the position of strategist for all Dalek time missions. If given the opportunity, he could effectively take old Dalek plans which had failed and reshape them into victories.
At one point, the Eighth Doctor noted he "wasn't concerned with just conquest and extermination for the sake of it", but "was far more subtler than that". Knowing this, he regarded him as "the deadliest Dalek of all".
The Dalek Time Controller oversaw the New Dalek Paradigm's scheme to transform the 400 Sunlight Worlds into "a billion Skaros." He manipulated the TARDIS' destinations in the Time Vortex and led the Eleventh Doctor into uncovering the secrets to the Cradle of the Gods. The Time Controller also outranked the Dalek Supreme on this mission and countermanded the Supreme's orders to take action, lest it disrupts the flow of time. This Dalek was described as being of a similar design to the Time War Dalek, but having a shifting colour scheme and shape, with a neck section surrounded by rings and containing the Time Vortex. A wavering effect surrounded the rings.
The Time Controller posed as the Dalek Litigator — a judge in the law courts of the Sunlight Worlds. He acted as the prosecution when the Eleventh Doctor was placed on trial on two occasions for claiming the Daleks were evil (something considered a hate crime), outwitting him on both occasions.
The plan backfired when the Doctor managed to convince a Dalek puppet, Jenibeth Blakely, to turn on the Time Controller. While undamaged by the fire from Jenibeth's weaponry, the Time Controller promptly retreated. (PROSE: The Dalek Generation)
When the Daleks tracked Patient Zero to the Amethyst Viral Containment Station in the past the Time Controller commanded a mission sent there, planning to move the station through time to the Daleks. The Sixth Doctor damaged their operations and left them trying to fend off an explosion. However, the Time Controller realised the explosion at the Amethyst Viral Containment Station had caused the viruses to be scattered through time and allowed it to happen. The Doctor believed the Time Controller had been destroyed in the explosion. (AUDIO: Patient Zero)
However, he was blasted back through the Time Vortex to the late 22nd century where he was retrieved by the Daleks, though he was decaying from his experience. They contacted the Monk due to his temporal knowledge, and he was able to repair him. The Dalek Time Controller took control over Dalek operation and orchestrated the second Dalek invasion of Earth, forcing the Monk to release another plague to weaken humanity. He planned to use Earth as a spaceship containing the viruses from the Viral Station, having seen where they would end up while it was in the Vortex and installing a time engine into Earth to travel to this point. The plague planet could then be piloted through the Universe, infecting entire planets. Ultimately, the Time Controller, and all Daleks on his ship, were dragged into a time warp thanks to Lucie Miller crashing a Dalek Saucer containing a bomb into the mine. (AUDIO: Lucie Miller / To the Death)
However, the Time Controller was saved from destruction by Kotris. (AUDIO: X and the Daleks) From then he oversaw the chasing of the Eighth Doctor and Molly O'Sullivan through time and space, (AUDIO: Fugitives) by using a relativity map and a Temporal Chamber to create a Space-time projector. Using retro-genitor particles implanted inside Molly, he and Kotris planned to destroy the Time Lords. (AUDIO: Tangled Web, X and the Daleks) After Straxus killed himself, he erased Kotris from history. The Dalek Time Controller's plans involving Kotris were therefore erased. The Dalek Time Controller was aware of the change in history while it occurred, and swore to Kotris before he was erased, that he would destroy the Time Lords. (AUDIO: X and the Daleks)
The Dalek Time Controller oversaw the invasion of Nixyce VII, and created mines in the planet to create a Dalek superweapon. The Doctor detonated a bomb located on a nearby Dalek in the Time Controller's chamber, damaging the Time Controller and causing him to flee to his ship in orbit above the planet. (AUDIO: The Traitor) Rather than destroying the weapon, the Doctor asked for the Dalek Time Controller's help in defeating the Eminence, who posed a bigger threat to the Daleks than the Doctor. (AUDIO: Eyes of the Master) The Dalek Time Controller agreed, and used the weapon to destroy the Eminence fleet. (AUDIO: Time's Horizon)
The Time Controller later arrived in Paris, where he created Adelaine Dutemps from his own DNA. The Controller then created Dalek Time Strategists from the criminal minds that Adelaine dealt with. He used the power of the Time Vortex to create them. It wanted to create the a new Paradigm so that he could control Daleks throughout all time. The Time Controller asked Liv Chenka some questions about The Eminence war, and the Doctor's involvement. When the Time Controller opened his casing to show Liv his eye, it was dark like Molly's. The Time Controller used the Red Pagoda and the TARDIS to create a larger shell. (AUDIO: The Monster of Montmartre)
The Controller travelled with the Master to the control centre. The Controller wanted to find Markus Schriver. The Master told the Controller that they were running out of humans to convert into Daleks, so they were now using Sontarans. The Dalek Time Controller planned to betray the Master if the Doctor was well enough. After the Master's Dalek mutiny, he escaped with Liv and Molly in the TARDIS. (AUDIO: Master of the Daleks)
The Dalek Supreme came to believe that the Time Controller was no longer a pure enough Dalek, having lived outside time through so many time shifts. The Supreme believed him to have been destroyed, when in actuality The Dalek Time Controller had transferred his consciousness to the gas created by Markus Schriver, joining his personality with Schriver's and thus creating the Eminence. The Dalek Supreme then commissioned the creation of a new Dalek Time Controller from the remains of Adelaine Dutemps. (AUDIO: Eye of Darkness)
