receive the launch codes, the Ninth Doctor arranged for a Harpoon missile to demolish 10 Downing Street, ending the scheme and killing all but one of them who managed to escape through an emergency teleport. Jocrassa's sister Blon Fel-Fotch Pasameer-Day Slitheen, who had assumed the identity of Margaret Blaine of MI5, survived and reappeared in the episode "Boom Town". In the intervening six months, "Blaine" was elected as Lord Mayor of Cardiff and planned to leave Earth by using the energy from a new nuclear power station to interact with the Cardiff Rift, unconcerned that the planet would be destroyed in the process. Blon was stopped by the Doctor and his companions, and on exposure to the "heart" of the TARDIS, regressed to an egg. The Doctor took the egg to the hatcheries on Raxacoricofallapatorius so she could be given a second chance at life and be raised by a peaceful Raxacoricofallapatorian family. Some years after the events of "World War Three", in Revenge of the Slitheen (set in either 2008 or 2009) another group of Slitheen infiltrated a construction company with plans to turn off the Sun and destroy Earth by draining the world's energy to avenge the deaths of the Pasameer-Days. It is mentioned that the Judoon have begun to force out the Slitheen, and the various other Raxacoricofallapatorian families have been working against them. The families Blathereen and Hostrazeen are mentioned as part of the Raxacoricofallapatorian ruling bodies, the Senate and the Grand Council. After Commander Glune was killed by Maria Jackson, Luke Smith was able to trick the Slitheen into resetting their machinery, which then malfunctioned and exploded. Two of the remaining Slitheen (Glune's siblings Kist and Bloorm) were killed, and the others escaped, including Kist's son Korst, the first child Slitheen to appear. The Slitheen returned in The Lost Boy where, using the newer compression technology, two Slitheen named Dax and Bloorm posed as Luke's 'real' parents Jay and Heidi Stafford. They were under the command of Korst, who planned to avenge the deaths of his family. Another Slitheen (who was either a child or a short adult) appeared in the 2009 special "From Raxacoricofallapatorius with Love", masquerading as a galactic diplomat in an attempt to steal Sarah Jane's robot dog K-9. The Slitheen appeared in the New Series Adventures novel The Monsters Inside by Stephen Cole. When the Ninth Doctor and Rose are arrested
