London's Super Guardian
From Tardis Wiki, the free Doctor Who reference
A Super Guardian Dalek was stationed in London, one of four Super Guardians assigned to cities during the Dalek invasion of Earth in the year 2254 each to protect an ozone destroying pod to aid the invasion. It looked like a large grey Dalek War Machine wih a franctic manipulator arm and tank trails, its mutant could launch rockets and looked like the ones put by Daleks to dwell in London's sewers and feed on humans.
