Biography
Kist, his son and his brother invaded a school in London. Kist disguised himself as one of the teachers, Tim Jeffery, so that with other family members all over the world, they could turn off the Sun. When Sarah Jane Smith intervened, Kist was killed by the failing technology, begging for Korst's life to be spared. (SJA: Revenge of the Slitheen)
