"Mutant Daleks" was the name given by the Daleks on board the Dalek Supreme's command ship to the Daleks that were created by Professor Martez.

He used human tissue to create them, first from corpses, then from living people. When the original Daleks were made aware of the mutants' existence, they saw them as a threat to the purity of their race. They diverted an asteroid to Red Rocket Rising to destroy them, then came themselves to kill any that survived. The Mutant Daleks were destroyed in a battle between both Dalek factions and humans led by Tom Cardwell. (AUDIO: Blood of the Daleks)
