Dalek duplicate
Dalek duplicates, also known as Dalek replicants, were genetically engineered soldiers created by the Daleks. They were conceived as copies of individuals killed by the Daleks, to be used in undercover work. Despite this, the duplicates retained some memories, leading them to fight their programming. (AUDIO: Enemy of the Daleks) According to some accounts, they were androids. (COMIC: The Dalek Project, AUDIO: The Fearless: Part 4)
Biology
Duplicates were incredibly strong and were able to perfectly mimic voices. Among some issues with replicants were their cold skin (AUDIO: The Genocide Machine) and eye colour, which the Daleks could never get right. (AUDIO: Daleks Among Us) Duplicates emitted a magnetic field. (COMIC: The Dalek Project)
