10 Best Doctor Who Spinoff Villains
8. Korst Gogg Thek Lutiven-Day Slitheen – The Sarah Jane Adventures
The Slitheen are often regarded as one of the worst villains in the Doctor Who universe. Although they did appeal to younger fans of the series, so it was fitting for them to feature in a spinoff aimed at a child audience. Korst Gogg Thek stands out for being the first child Slitheen appearing onscreen and the first reoccurring villain in the series.
First appearing alongside his uncle and father as they plotted to drain the Earth (and sun) of its energy from Park Vale School which Korst attended, under the Alias ‘Carl’, along with Luke, Maria and Clyde. When the plan was foiled, he escaped while his family died.
Plotting revenge on Sarah Jane Smith, he formed a scheme with the mysterious Xylok to drain Luke’s mind of telekinetic energy. However, The Xylok double crossed him and he was forced into helping The Bannerman Road Gang save Earth and prevent the moon from crashing into the planet.
