Blon Fel-Fotch Passameer-Day Slitheen
From Tardis Wiki, the free Doctor Who reference
Blon Fel-Fotch Passameer-Day Slitheen was a member of the criminal Raxacoricofallapatorian Slitheen family who took the skin of the Human polotician Margaret Blaine when the family attempted to trigger nuclear devastation on Earth, to sell the radioactive remains as starship fuel. (DW: World War Three)
Blon escaped the destruction of Downing Street and became mayor of Cardiff, beginning the Blaidd Drwg nuclear power plant project above the Cardiff rift to destroy Earth, not to sell as fuel, but with the purpose of using a tribophysical waveform macro-kinetic extrapolator to escape Earth. (DW: Boom Town)
