Spy Dalek

The dormant Spy Dalek was a severely decaying Kaled mutant in a Dalek casing used as a means of security to watch the grounds on the Somerset house in 2003, which was actually a Dalek colony in disguise.

Biography
This particular Dalek was in poor condition after surviving the Dalek destruction at the hands of the First Doctor (The Daleks Master Plan). Its superiors reconstructed its casing instead of repairing it to make it a more than capable security machine. It spotted the Doctor when he arrived in Somerset, 2003, and did not react even when the Doctor slid the casing open to take a whiff of its rotting body, or when he forcefully plucked its eyestalk off. After using some kind of magnetic trick to reattach its eye, the Spy Dalek looked around and sent the security footage to the first Gold Dalek and the colony was alerted of the Time Lord's presence. After the Daleks were all destroyed, the Doctor visited the Spy Dalek one last time and accidentally set off its defensive blast. After kicking it, removing its eye a second time and walking off playing his penny whistle, the Dalek reattached its eye again and sent out a distress signal, uttering the words, "Help... me..." (Colony of the Daleks).
