Harvey (Asylum of the Daleks)

Harvey was a stranded crew member of the  Alaska spaceship. Shortly after the ship crashed, Harvey went out and froze to death, with the cold perfectly preserving his body and the nanocloud converting his corpse into a Dalek puppet. A year later, he showed the Doctor and  Amy to his ship. His crew, last he remembered, were still alive, but were found dead upon re-entering the Alaska, and, while initially shocked, Harvey eventually remembered that he, too, was dead. At this point, his Dalek programming became active, and he attacked the Doctor and his companions, only to be fended off by a fire extinguisher and locked inside a storage space. When the Parliment of the Daleks destroyed the planet, Harvey was finally allowed to rest in peace.

Behind the scenes
Harvey's only shipmate known to have survived the crash was Oswin Oswald; she was completely converted to a Dalek. Doctor Who premiered on 23 November 1963 with An Unearthly Child, the day after President John F. Kennedy was assassinated by Lee Harvey Oswald. Oswald and the Kennedy assassination are oft referenced in the DWU.
