Barzilla

 was a human-populated planet. Sara Kingdom once used it as a decoy to attract a Dalek invasion force. The plan, authorised by the Space Security Service, was to lure the Daleks to Barzilla to prevent them from attacking "the Big Four".

Sara managed to make the semi-barren and largely defenceless world attractive to the Daleks by spreading a rumour that she and the planet's leader, Harker Libra, had discovered a huge vein of gold in one of the planet's abandoned diamond mines. This rumour got back to the Golden Dalek though one of the Daleks' humanoid spies. Because the Daleks saw the acquisition of wealth a valid route to power, they were easily tempted to divert to Barzilla — only to discover that the SSS had laid a effective trap for them. The entire Dalek fleet was annihilated.

Little was known about the planet outside of this incident. However, it had suffered nuclear attack some 2000 years before the Dalek invasion, which had rendered the planet less habitable. It was prone to long periods of drought because the nuclear bombardment had permanently changed the planet's weather patterns. (DAN: The Outlaw Planet)
