The Slitheen Family are a family of Raxacoricofallapatorian criminals from the planet Raxacoricofallapatorius who seized control of the UK government and attempted to start a nuclear war, their ultimate aim being to turn the Earth into a huge nuclear reactor pile and sell its remains off as starship fuel. (Aliens of London ), (World War Three ). The Slitheen are rivals (and “cousins”) with another family from the same planet, the Blathereen (The Monsters Inside).
The Slitheen had developed a method of disguising themselves as humans by first obtaining the skin of a dead human — referred to as a skin suit — and compressing themselves into it. In order for this to work the human victim needed to be heavy set, and the compression had a side effect: a gas exchange occurs which causes the disguised Slitheen to frequently expel gas with a sound similar to human flatulation

They are descendants of the Huspick Degenerate and cousins of the Rackateen. The whole family has been exiled from their planet, with the death penalty if they return. (Monsters and Villains). Blon Fel Fotch Pasameer-Day Slitheen, the Slitheen disguised as Margaret Blaine of MI5 and lone survivor of the Slitheen group which tried to destroy Earth in 2006, became Mayor of Cardiff and attempted to destroy it. (Boom Town).

Of all the aliens created for the revived series, the Slitheen have been featured the most, having appeared in six television stories, two books and one short story.
According to the reference book, The Visual Dictionary, which this wiki does not count as a valid source, the Slitheen were one the oldest families on Raxacoricofallapatorius
