Glune Fex Fize Sharlaveer-Slam Slitheen was a member of the Slitheen family from Raxacoricofallapatorius. He was the brother of Kist Magg Thek Lutiven-Day Slitheen and the uncle of Korst Gogg Thek Lutiven-Day Slitheen.
Coldfire Construction, under control by the Slitheen, who wished to avenge the deaths of the family members killed at 10 Downing Street, had built their final transducer in the guise of a technology block inside Park Vale Comprehensive School over summer 2008. The transducers were to be used absorb all the energy out of the Sun, destroying the Earth, while the Slitheen lay safe inside a hidden room in the technology blocks across Earth. They would then use the profits from Earth's remains to buy battlecruisers to destroy Raxacoricofallapatorius' Grand Council.
Around 2008, Glune posed as Greg Blakeman, Park Vale Comprehensive School's headmaster. In September 2008, he activated the transducers on a trial run but they failed. When Kist Magg Thek gained the right equation for the capacitor from Luke Smith, the plan began again, but ultimately failed.
When the plan was found out, he was killed by Maria Jackson when she threw vinegar at him. (TV: Revenge of the Slitheen)
