The Renegade Daleks were a faction of Daleks opposed to Davros and Davros' faction, the Imperial Daleks during the Imperial-Renegade Dalek Civil War. The Renegade Daleks remained loyal to the Supreme Dalek, based on the planet Skaro (DW: Revelation of the Daleks) which the Imperials would later take over. (DWM: Emperor of the Daleks, DW: Remembrance of the Daleks)
- The Renegade faction doubtless did not call themselves by that name, however, Davros referred to them as such. They may well have simply referred to themselve as the Dalek Empire.
Unlke the off-white and gold Imperials, the Renegades had gray and black livery. As well as fighting the Imperials for political reasons, the Renegades loathed the Imperials because, like the Imperials, they adhered to a xenophobic and racist ideology. Davros had altered his basic Daleks, physically fusing his Daleks into the Dalek shell. The Renegades found this unacceptable and believed themselves superior, which was proved when they defeated Imperial Daleks with ease forcing the Imperials to call reinforcements in the form of the Special Weapons Dalek.
While the Imperial Daleks could hover and fly, the Renegades could only hover a short distances off the ground. (DWM: Emperor of the Daleks)
The Special Weapons Dalek (or, if more than one existed) changed sides to the Imperials. (DWM: Emperor of the Daleks) They also do not seem to actually care about the human race and just simply ignore them only exterminating them if they got in their way but otherwise they barely care about the existance of humans.
Alternate Timeline
In one timeline, the original Daleks simply abandoned Skaro and Davros rather than try to kill him. These Daleks, which went on to carve out an interstellar empire, these were called Renegade Daleks by Davros. (DWU: Masters of War)
