The Passameer-Day Slitheen tried to reduce the Earth to nuclear fuel in March 2006, but most of them were destroyed in a missile attack by Mickey Smith. (TV: World War Three, Boom Town) Around March 2007, the Slitheen took over a building company called Coldfire Construction and tried to destroy the Earth by shutting down the Sun with a loop of transducers built around the world by Coldfire. They would have used the profits from the Earth's remains to avenge their relatives and to buy a fleet of starcruisers to destroy Raxacoricofallapatorius' Grand Council.
