The Cult of Skaro are the highest ranking Daleks in the Dalek hierarchy. Trained to think independently so to ensure the Daleks' survival, the Cult of Skaro are the main antagonists of the second season of the 2000s reboot of Doctor Who. The Cult is a minor faction in the Non Disney Villains Tournament, though their leader, Dalek Sec, has a more crucial role in the war.
Non Disney Villains Tournament
The Cult of Skaro enters into a meeting with Scorpius, who hopes to ally with them. Being speciesist Daleks, the Cult refuses and tries to "exterminate" the enemy. Scorpius, however, is prepared, calling in a full attack squad. In the resulting firefight, two members of the Cult of Skaro, Daleks Jast and Thay, are destroyed. The leader, Dalek Sec, manages to escape, but the last member, Dalek Caan, is tortured into giving up information about the Dalek fleet.
