Season Twenty Three - 1986 (The Trial of a Time Lord)
The second fragment of prosecution evidence in the Doctor's trial is his adventure on Thoros Beta:
The Doctor and Peri visit Thoros Beta, the home planet of Sil. Peri is impressed with the fluorescent beaches and water. When they eventually find a way off the beach they are attacked by a genetically enhanced creature.
The Doctor and Peri find that things are not well on the planet. Peri is disgusted to find that the Doctor has brought her to Sil's home planet, and Sil is less than impressed also. The Mentors have a problem: Their leader's brain is expanding, and soon it will be too large for his skull, which will kill him.
They have brought in a scientist, Crozier, to find a way to relieve Kiv's suffering. The Doctor is tested for viability as a host for Kiv's brain. After being subjected to one of Crozier's machines the Doctor starts to act selfishly, even to the point of betraying Peri.
The Doctor's allegiance is unknown - he seems to be helping the Mentors, although he pretends it is a plot and helps a trapped warrior king to free the Thoros Alphans that are being held for experimentation. Chaos breaks out, and Peri is taken by Crozier, and found to be the perfect donor, although Sil is not happy about the choice; but it would save Kiv.
The Time Lords think that the Doctor has gone too far, and allowed the situation to get out of hand. To this end they take him out of time. They also trap King Ycarnos in a time bubble, and release him when the time is right.
Inside the laboratory Kiv's mind has been transplanted into Peri's. As Kiv awakes, Ycarnos is released. Seeing that Kiv now inhabits the body of his Queen, he kills her ...
