The Master of the Trods was an individual who travelled to Trodos and reactivated the Trods which he found there. He became their new Master (replacing MacTaggart) and planned a special punishment for the First Doctor, John and Gillian for defeating them earlier. He drew the TARDIS to a planet on which he had constructed a city, where the Super Trod told them that the buildings were booby-trapped and that they were to avoid them using only their wits. However, the Doctor and his companions escaped through a hole created by an explosion and made their way to the Master's tower. He tried to kill them, but accidentally threw himself through a window and fell to his death. (COMIC: Return of the Trods)
