Sukhrit

Sukhrit was the brother of Annajin Valentin. He was possessed by the Puppeteer, an alien that took over its victims' minds and caused them to act violently. By the time Annajin, on the trail of the Puppeteer, met the Fourth Doctor and Oliver Day, it had left Sukhrit and was possessing Oliver. The Doctor and Annajin defeated the Puppeteer, and Sukhrit eventually recovered from the possession. (PROSE: Puppeteer)
