K is for... Kane (1)

Kane was a criminal mastermind from the planet Proamon. He and his partner and lover Xana were eventually hunted down. She was killed and he captured. He was exiled alone on a spacecraft to the planet Svartos, which was a frozen world with a permanent dark side. The power source for the ship was removed and hidden within a biomechanoid creature which was heavily armed. The power source was known as the "Dragonfire" and the biomechanoid the "Dragon".

The people of Proamon existed only at temperatures below freezing, meaning Kane could not venture far from a freezing cabinet which kept his body temperature low. His touch could kill human beings, but to spend any length of time in their environment would prove fatal to him. He was unable to go and find the Dragonfire.

He turned his ship into a trading post for travellers, known as Iceworld. Through this he began recruiting an army so that he could get his revenge on his home planet. People were abducted from Iceworld, or blackmailed into joining him. Their memories were wiped by rapid freezing, turning them into mindless zombies, obedient only to him.

He commissioned an ice sculpture of Xana, killing the sculptor when he had finished the work as only he was permitted to look upon it. It was destroyed during a failed coup by some of his officers, who tried to kill him by raising the temperature of his inner sanctum.

Kane eventually tracked down the Dragonfire by manipulating the intergalactic conman Sabalom Glitz, who was being assisted by the Doctor.

However, the Doctor was able to show him that during the centuries of his imprisonment, Proamon had been destroyed by its own sun. 

Devoid of purpose, Kane elected to open his sun-shields and killed himself, his body melting away to nothing in seconds.

Played by: Edward Peel. Appearances: Dragonfire (1987).

• If you like to count the mini-episodes which are used as trailers for the Blu-ray box-sets as canon, then Kane survived his death on Iceworld. In 24 Carat! he tried to sell a face cream product called "Mr Melty" to Melanie Bush.
