K9 joins as a companion in The Invisible Enemy. Leela leaves to stay on Gallifrey at the end of The Invasion of Time.
Horror of Fang Rock
The Doctor promises to take Leela to Brighton for a holiday. Instead, the TARDIS materializes on Fang Rock, inhabited only by the keepers of the Lighthouse. The light behaves erratically, causing a clipper to run aground. The lighthouse engineer dies in mysterious circumstances, and the remaining keepers and the clipper survivors start to die one by one. Can the Doctor and Leela uncover the mystery before everyone is dead?
The Invisible Enemy
A sentient space virus attacks the crew of a shuttlecraft on its way to a base of Titan. The virus also enters the TARDIS circuits and infects the Doctor, who starts behaving strangely, landing the TARDIS on Titan. The shuttle crew and the Doctor then attempt to kill Leela. Can she survive and help the Doctor fight the virus that's controlling him?

The Sun Makers
Arriving at a human colony living in an artificial biosphere on Pluto, the Doctor discovers a citizen on the verge of committing suicide because of an impossible tax burden.

He aids the Minyans to locate their goal, a vessel known as P7E which is now at the center of an asteroid. As the Minyans attempt to recover the gene bank that contains their race, they clash with the half-robot/half-Minyan rulers of the asteroid.
