London

London is the capital city of the United Kingdom, located in the south of England and home to around eight million people (and also a big clock). Unlike some other major cities on Earth (and even some other places in the UK) London managed to avoid too much major Transformer activity in the 1980s.
And then came Generation 2...
Fiction
Marvel Comics continuity
Generation 1
London contains the headquarters for Action Force's European branch.
Megatron (or a clone thereof) was teleported underneath London, and roamed about ancient Roman sewers until he was encountered by Susan Hoffman and her team. Both Action Force and the Autobots turned up to investigate, and the two teams had to work together to stop Megatron as he tore through the London Docklands. Eventually Centurion gave his life to stop the Decepticon, but not before widespread destruction to the area had been caused. Ancient Relics!
Richard Branson would later salvage Megatron and Centurion's bodies from the River Thames as a publicity stunt - making it easier for the Seacon Jawbreaker, along with Thrust, Ramjet, Dirge and Blitzwing, to capture them. Salvage!
Fleetway Generation 2 comic
Bludgeon and his Decepticon army attacked London en masse to attract Optimus Prime's attention and succeeded — Prime's Autobots, Grimlock's Dinobots and an upgraded Megatron were drawn into the fray. The devastation caused to London was immense; the death toll and long-term effects are unknown. At one point, the Skyscorchers were seen bombing Big Ben and the Houses of Parliament.
