Superior in every way to previous Dalek drones, those of the Time War were enhanced to genius level. This was deemed necessary in order to defeat opponents in a war in which time itself could be a weapon. The Emperor ensured that all his soldiers of the military caste were obedient, to the extent that they often became lost without standing orders to follow. Science Drones maintained a certain level of independence. All drones were encased in the newly developed Mark Five Travel Machine which offered full flight capability and resistance to not only normal weapons but also limited protection against temporal ones. All Daleks were encased in Bronze casings, with the Dalek's caste and identifier indicated by symbols on the front of the Dalek dome, beneath the eye-stalk.
On his first encounter with a Dalek since the Time War, the Doctor summarised a Dalek drone to its captors as:
"A nightmare. It's a mutation. The Dalek race was genetically engineered. Every single emotion was removed except hate."
-- The Doctor, Dalek
The nature of the Mark Five Travel Machine eliminated the need for any Special Weapon Casings. Each drone became a literal tank, capable of holding their own against any foe. The drones of the Time War were ultimately destroyed by the actions of the Time Lords, particularly those of the Doctor. Despite this, a number of stranded drones survived, scattered throughout time and space. One such drone crashed on Earth and was passed from collector to collector before being experimented on and tortured in Nevada, USA by Henry Van Statten. This lone survivor encountered the Doctor and became genetically corrupted by his travelling companion. Ultimately it committed suicide. Another was sent to Earth's past during the War to spread the Dalek Factor. This plan was also defeated by the Doctor.
