Dalek Killer
From Tardis Wiki, the free Doctor Who reference
Dalek Killers were Human criminals who had chosen, over execution, to be teleported to a planet in the Dalek Empire and made to kill as many Daleks as possible before being exterminated. The odds of survival were 600 million to one. The most notorious Dalek Killer was Abslom Daak. (DWM: Abslom Daak... Dalek Killer)
