Cult of Skaro

The Cult of Skaro, named after the Dalek homeworld, was a secret group of four Renegade Daleks made up of three Dalek drones and one Supreme Dalek.

Purpose
The Cult of Skaro were assigned the task of furthering the Dalek cause through the development of new and unorthodox ideas and strategies. The leader of the Cult claimed that it was created primarily to further the process of Dalek evolution. Their willingness to adopt alien modes of thought was demonstrated by the fact that they had individual names, a concept most Daleks found abhorrent. Led by Sec, the Black Dalek, they answered to no one, not even the Dalek Emperor, although they still revered him. (TV: Doomsday)

Origins
The Cult of Skaro were at first just four ordinary Daleks. Dalek Sec was a commander of a Dalek group sent to wipe out the remnants of the Mechanoids which they succeeded in doing. After doing this all four of them were promoted to become the Cult of Skaro. They were given their names - making them the only Daleks with names - and Dalek Sec was chosen their leader. (PROSE: Birth of a Legend)

Survival
They were a secret order who were to think like their enemies in order to destroy them, although their original purpose was to imagine new ways of survival. During the Last Great Time War, they operated as a final strategic reserve - rather than fighting, they escaped into the space between universes, along with what they called the Genesis Ark, a piece of Time Lord technology. Having left the universe, they were not caught in the destruction of the Dalek fleet. (TV: Army of Ghosts / Doomsday, Daleks in Manhattan)

Conflict with the Cybermen
The Torchwood Institute's meddling began to open the barrier to the Void which had been broken down by the Cult's Void ship. Torchwood Tower, known to the public as Canary Wharf, had been built around the gap into the Void so that Torchwood One could study it and use its energy. When the Void Ship opened, the Cult exited the ship and declared war - or "pest control" - against the Cybermen that had invaded Earth from Pete's World, leading to the Battle of Canary Wharf. They then opened the Genesis Ark and released thousands of Daleks onto England. All these Daleks were sucked into the void along with the Cybermen. The Cult survived by using an emergency temporal shift. (TV: Doomsday)

In New York City
The Cult escaped the battle through a temporal shift and ended up in New York City in 1930. They infiltrated the construction of the Empire State Building and began what they called the "Final Experiment" - the creation of a new Dalek race. (TV: Daleks in Manhattan / Evolution of the Daleks) Inside the sewers below the Empire State Building they set up a genetic laboratory and began attempting to create new Dalek embryos. After the failure of this experiment, they tried thinking, as the Cult was designed to, and came up with the idea that they should use Earth's greatest resource, its people. They placed Dalekanium upon the mast of the Empire State Building and devised a plan to fuse the DNA of Daleks and humans using an incoming ray of gamma radiation from the sun. Dalek Sec tested this on Mr Diagoras and he became a Dalek-human hybrid, now with human thoughts and emotions. Dalek Sec wanted to make the Dalek-humans' DNA 90% human. The other Daleks, although bred to obey Sec, knew it was against the Dalek cause and so changed the DNA to 100% Dalek and imprisoned Dalek Sec. Dalek Sec was later exterminated accidentally after the other Cult members fired their gunsticks at the Tenth Doctor.

The Doctor got in the way of the blast of gamma radiation and so infused the DNA with some of his own. Therefore the humans rebelled and killed Dalek Thay and Dalek Jast. The Doctor offered Dalek Caan—the last surviving Dalek—help but instead of taking it, Caan used an emergency temporal shift to escape (TV: Evolution of the Daleks). Caan returned to the Last Great Time War (despite the fact that the war was time-locked) and rescued Davros from his doomed command ship. Caan, however, became insane during his successful attempt at rescuing Davros. Caan, the last remaining member of the Cult of Skaro, was presumed killed when the Crucible was destroyed.
