Dalek puppet

Dalek puppets were beings who had been taken by the Daleks and partially converted to serve them as slaves. These slaves were used as sleeper agents, and when activated would have a miniature Dalek eyestalk extend from their forehead and a miniature Dalek gunstick from his or her hand.

The process occurred when any unprotected non-Dalek entered the Dalek Asylum; the air contained a nanocloud that would slowly convert the victim into an unwitting servant of the Daleks. Not even death could protect them from this fate: the conversion process worked on dead amd living flesh alike, and could turn innocent corpses into shambling, zombie-like creatures.
