This unnamed young member of the Slitheen, a criminal family from Raxocoricofallapatorius and appears as a minor antagonist in The Sarah Jane Adventures episode The Gift. In 2009, he used the body of a young boy called Chris and stole a matter compressor from the Pharos Institute (as he had accidentally sat on the last one) and was pursued by Sarah Jane Smith and her gang. He eventually remove his human disguise and met up with older Slitheen who was disguised as a teenage boy called Dave and planned to use the matter compressor to turn Earth into a diamond. But before they could do so Leef Apple Glyn Slitheen-Blathereen and her husband Tree Lorn Acre Slitheen-Blatereen arrived and teleported the two Slitheen away to be tried and executed.
Though since Leef and Tree were later revealed to be criminals too and took after their Slitheen relatives, it is possible that they teleported Chris and Dave to safety rather than be executed.
As Chris, he is played by Calvin Dean who also voices his Slitheen form which is played by Jimmy Vee.
- He is the second child Slitheen to appear in the series. The first being Korst Gogg Thek Lutiven-Day Slitheen.
