For questions about the Daleks, an alien race in the TV series Doctor Who. Always use in conjunction with the [doctor-who] tag.
Daleks were the mutated descendants of the Kaleds of the planet Skaro. They fought the Time Lords in the Last Great Time War, ending in the near-total destruction of both races. Regarded by the Doctor as his greatest enemy, the Daleks were hated and feared throughout time and space. They were the oldest and most frequent foes of the Doctor, having faced him several times in every one of his incarnations.
