Grendel of Gracht

Count Grendel of Gracht was a Taran count and cousin of Tara's rightful ruler prince Reynart, who he had imprisoned along with princess Strella. He made a plan to become king of Tara. His plan was revealed by the Doctor and Romana, and he was defeated in a swordfight by the Doctor. Following this, he was exiled by Reynart. (DW: The Androids of Tara) Grendel later returned, repairing and allying himself with the Kandy Man, who had faced the Doctor in his seventh incarnation. Grendel was once again defeated by the Doctor. (VD: The Trials of Tara)
