Slitheen-Blathereen family


 * See also the Slitheen family and Blathereen family.

The Slitheen-Blathereen family were a Raxacoricofallapatorian criminal family created when the Slitheen family and Blathereen family intermingled. They had no respect for the Blathereen, believing them to be weak and the known members were a red-brown colour, as opposed to the green of the Slitheen.

History
Two Slitheen-Blathereen, Leef Apple Glyn Slitheen-Blathereen and Tree Lorn Acre Slitheen-Blathereen had become addicted to Rakweed. They planned to cover the Earth with it, then sell it to others. Around 2009 they based themselves in Antarctica, Earth and managed to capture two Slitheen, in front of Sarah Jane Smith, Luke Smith, Rani Chandra and Clyde Langer. They pretended to be peaceful Blathereen and gave them Rakweed as a "gift". The Rakweed soon spread around London, infecting Luke along the way. Sarah Jane eventually arrived at their spacecraft by teleporting, but was captured by them. She was able to break out after learning of their plans and then escaped home. Mr Smith was able to destroy the Rakweed by using high-pitched noises of every electronic device in the area to destroy them. When the Slitheen-Blathereen followed them to London, Sarah Jane was forced to destroy them by activating the noise again, which caused to Rakweed in their stomach to break down into methane, making their stomaches explode.

Technology
The Slitheen-Blathereen had advanced technology. Tree Slitheen-Blathereen was capable of genetically modifying the Rakweed to grow even faster. They had a spaceship which was capable of remote teleportation and tracking of the growth of Rakweed in London. They used bracelets which could activate the teleports, fire lasers and hack into advanced computer systems. (TV: The Gift)

Behind the scenes

 * The two Blathereen suits were actually left overs from a unused project in which the Rackateen would appear to Sarah Jane.
 * A Blathereen appeared in a specially filmed trailer aired before the premiere of Series 3 of The Sarah Jane Adventures. The trailer had Sarah Jane and the gang coming across an old lady, a postman, and a teenage girl, with one of the three being a Blathereen in disguise. The viewer, having been given the sonic lipstick by Sarah Jane, had to choose which one they believed to be the Blathereen. The correct answer was later revealed to be the postman.
 * A Blathereen appears in Level 6 of the online game, Think Before You Sonic!. It is armed with an energy weapon and fires at Rani, who uses her sonic tool (lipstick or screwdriver) to draw a line which blocks its attacks so she can make it to the TARDIS.
