Goth

Goth was a Time Lord, he travelled to the planet Tersurus and found the dying Master there. Goth then assassinated the Lord President of Gallifrey and lured the Doctor to Gallifrey. Goth died battling the Doctor in The Matrix on the Master's orders. (DW: The Deadly Assassin) Goth had a brother named Rath. (NA: Blood Harvest)


 * A Time Lord who looked very like Goth presided over the trial of the Doctor prior to the Doctor's exile on Earth, leaving open the possibility of Goth's involvement with this decision.
