Biography
On behalf of the of Celestial Intervention Agency, Goth masqueraded as the fictional character Lemuel Gulliver in the Land of Fiction to monitor the Second Doctor. (TV: The Mind Robber, PROSE: Future Imperfect) Shortly after, on Gallifrey, Goth, with two other Time Lords, presided over the trial of the Doctor. This decided his exile on Earth. (TV: The War Games, PROSE: Future Imperfect)

Later, Goth became Chancellor and persuaded the CIA to send the Third Doctor to Peladon. (PROSE: Legacy)

He travelled to the planet Tersurus and found, who was now at the end of his regeneration cycle and physically little more than a decaying corpse. Aware by now that the Lord President did not intend to name Goth as his successor, the Chancellor entered into an uneasy alliance with the Master, who promised him the presidency in exchange for helping to kill the Fourth Doctor.

Goth subsequently assassinated the President before he could announce his successor, setting up the Doctor as an unwitting decoy assassin. The result should have been an unopposed election for the office. However, the Doctor announced his own candidacy to buy himself time to investigate.

Inside the Matrix, Goth fought the Doctor, initially using his knowledge of the Matrix's workings to his advantage. The Doctor soon gained the upper hand however, and the infuriated Master tried to overload the Matrix by sending a massive energy spike through Goth's brain.

The Doctor escaped from the Matrix in time, but the spike had fatally damaged Goth's brain and destroyed his regeneration cycle. (PROSE: Legacy of the Daleks) The Doctor found Goth and the seemingly dead (but actually self-sedated) Master not long after. The dying Chancellor told the Doctor how he and the Master had come to be allies, and why he wanted to kill the previous President.

Goth died shortly afterwards, and it was decided by Borusa to cover up the actual truth of his death. The population was told that Goth had heroically sacrificed his life to kill the Master. (TV: The Deadly Assassin)
