Byzar Janto

 was the closest thing to a medical officer for Koth's forces. He couldn't remember what happened to the previous one, but was sure he was fat. Janto was motivated to join his the cause due to losing his wife. He wasn't as sure about the revolution as the rest of his forces, as he was the only one unable to be influenced by Koth's mental powers. He remarked that since C'rizz was terrifyingly trusting that his race, the Eutermesans, must be dwindling in numbers. He helped the Eighth Doctor discover what he needed in the fungus. He later sacrificed himself to allow the Doctor to evacuate the caves. (AUDIO: The Twilight Kingdom)
