Florm Rox Fey Fenerill-Slam Slitheen was a member of the criminal family Slitheen.
Coldfire Construction had been taken over by the Slitheen around March 2007. Over the next eighteen months, they planned to build a loop of transducers to 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 use the profits from Earth's remains to buy battlecruisers to destroy Raxacoricofallapatorius' Grand Council. Florm posed as Janine, a Coldfire secretary in London after killing her and using her skin as a disguise.
In September 2008, after warning Sarah Jane Smith not to interfere, Florm tried to kill her, but Sarah Jane escaped. Later, she teleported to Park Vale School and helped restrain Sarah Jane and her gang from stopping their plan.
The final transducer's capacitor at Park Vale started overloading and the process was reset. When the Slitheen tried to make Luke Smith repair it, Sarah Jane passed him the sonic lipstick, which he used to damage the machinery. Florm was killed trying to teleport away.
