Jerak

Jarek was an experimental battle machine created by the Hakolian species to invade other planets. Jarek was sent to Earth after the Malus malfunctioned and was destroyed by the Fifth Doctor. He landed in the fields of the village of Hexen Bridge, where he worked with Matthew Hodge to find a cure for infertility. Using the Hakolians' knowledge of psychic science, he took control of the people of the village, and used their fear and hatred as energy to feed from, like the Malus in Little Hodcombe. He was defeated in the 2000s by the Seventh Doctor. (PDA: The Hollow Men)
