Chris Slitheen

Chris Slitheen was a member of the Slitheen family; he was very clumsy having sat on his own matter compressor, he also had a bad habit of pressing the wrong buttons. In 2009 he stole a Matter Compressor from the Pharos Institute, after which he was chased by Sarah Jane Smith and her Gang. He managed to escape and met with another Slitheen. They planned to use the matter compressor to turn the Earth into a giant diamond. After Sarah Jane failed to stop them, he grabbed Rani Chandra and threatened to kill her. However the Blathereen arrived to send him and his associate to be tried and executed. (SJA: The Gift)
