The Borad

The Karfelon known as The Borad began life as a scientist of the planet Karfel named Megelen, who encountered the Doctor. (The Karfelons used Borad a title, like President, rather than a name, however, when Megelen took power he referred to himself only by his title.)

During his first visit, the Doctor exposed Megelen to the ruling Council for unethical experiments on Morloxes, large reptiles indigenous to Karfel, and the chemical Mustakozene-80, which has the ability to fuse together different tissue as one creature.

After the Doctor left Karfel, Megelen was apparently able to continue his experiments, but was accidentally fused with one of the Morloxes via Mustakozene-80, becoming half Morlox and half Karfelon. He believed that his intelligence and longevity had increased.

Megelen also experimented with cloning and created at least one duplicate of himself after the accident. He was able to install himself as the sadistic and despotic ruler of Karfel under the name of the Borad. He never revealed himself in person, only via security monitors gave him the appearance of dignified old man. Mirrors throughout Karfel were banned as a result. Fear was enforced rigidly through the policing of androids; and all rebels are dealt with either by summary execution or despatch and death via the Timelash to 1179 Scotland, near Loch Ness.

Later history
Under the Borad's rule, the Karfelon people became disillusioned and rebellious, relations broke down with their former allies, the Bandrils, who threatened war after the Borad rescinded the grain supply treaty which had underpinned the relationship between the two civilizations.

A war with the Bandrils that would result in their use of bendalypse warheads which would wipe out all the Karfelons but leave the Morloxes and the Borad alive.

The Borad had started to re-create the Mustakozene-80 experiment using the Doctor's companion Peri Brown and a Morlox to create a second hybrid to mate with, with the intention to re-populate Karfel with their offspring.

The Doctor was able to trick a clone of the Borad into killing himself by manipulating the Borad through the use of Kontron crystals, leading to the Borad firing an energy weapon that was reflected back at himself, aging him to death. The Borad then confronted the Doctor following the death of his clone and the prevention of war with the Bandrils but became unbalanced after viewing a reflection of himself in a boarded-up mirror, revealing the reason he hid himself away, and in this state was thrown into the Timelash by the Doctor. The Doctor speculated that the Boarad would become the Loch Ness Monster. (DW: Timelash) However, the Borad died shortly after his arrival at Loch Ness. (EDA: The Taking of Planet 5)
