The Ten was the main alias used by the tenth incarnation of a Renegade Time Lord who suffered from regenerative dissonance.
Biography
He was known for his skills in hypnotism. He once killed a squad of Gallifreyan soldiers on Dalgar by hypnotising the first officer to kill the commander, then the second officer to the first officer, and so on. The Ten let Tessno survive the incident so that she could tell Gallifrey about what he had done. (AUDIO: Stop the Clock)
Legacy
The Ten's hypnotic abilities were strong enough to allow his successor to use a trick young students used to hide from their tutors which were strong enough to resist detection by the Time Lords to escape custody. (AUDIO: The Eleven)
The Ten was fascinated by his shifting memories when the Eleven approached Veklin outside of the City Museum. (AUDIO: The Side of the Angels)
