Lutiven-Day Slitheen

The Lutiven-Day Slitheen were a branch of the Raxacoricofallapatorian criminal family.

21st century
After the failed attempt by the Passameer-Day Slitheen to reduce the Earth to nuclear fuel in March 2006 (DW: Aliens of London/World War Three), in September 2008, Kist Magg Thek Lutiven-Day Slitheen and his son Korst joined Glune Fex Fize Sharlaveer-Slam Slitheen in a plan to avenge the Passameer-Day Branch, they took over a building company called Coldfire Construction and attempted to achieve the destruction of the Earth by shutting down the Sun. This group of Slitheen were eventually defeated by Sarah Jane Smith and her friends. Though Sarah did not mean to kill them, several ended up dead. Korst Gogg Thek Lutiven-Day Slitheen survived, but not his father. (SJA: Revenge of the Slitheen)

In February 2009, Korst teamed up with two other adult Slitheen to seek revenge and make the Moon crash into Earth. However, when they were betrayed by Mr Smith they helped Sarah Jane stop him, they then left the Earth. (SJA: The Lost Boy)

Named
The Lutiven-Day / Sharlaveer-Slam Slitheen Branch have some different physical appearances compared to the Pasameer-Day Slitheen branch. The Lutiven-Day are slightly greener and have bigger chests, they are slightly fatter and their feet are a different shape. A costume fault maybe but their upper chest seems to sag into the lower chest, with the Adult Slitheen only. This different appearance also cuts into Doctor Who when they made their Cameo in The End of Time.
