Florm Rox Fey Fenerill-Slam Slitheen (also known as Janine) is a member of the Slitheen Family, the sister of Glune Fex Fize Sharlaveer-Slam Slitheen and Kist Magg Thek Lutiven-Day Slitheen, the aunt of Korst Gogg Thek Lutiven-Day Slitheen and a supporting antagonist in the Sarah Jane Adventures episode "Revenge of the Slitheen".
In 2007, Florm along with her brother, nephew and some other Slitheen came to Earth to place transducers on it in order for them to "turn off the Sun" by using the transducers to take its energy and destroy Earth as part of the Slitheen's plan to avenge the deaths of the Passameer-Day branch of their family who died in the Doctor Who episode "World War Three". While undercover at Coldfire Construction, she killed Coldfire secretary Janine and used her skin as a disguise while the other Slitheen went undercover in schools and other locations around the world.
In 2008, a journalist named Sarah Jane Smith began investigating Coldfire. In her Janine disguise, Florm warned her to stop investigating before removing her skin suit and attacking her. Sarah Jane escaped by spraying her with perfume. Florm later teleported to Park Vale School to help restrain Sarah Jane and her friends to prevent them from damaging the machinery.
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 tried to escape but was killed by electricity.
