The Doctor (The Brain of Morbius)

Before leaving Gallifrey, the Doctor lived through several incarnations as Patience's husband. He came from a family of explorers, and he was not only led an expedition into deep time but also was one of the first Gallifreyans to enter the Time Vortex. (PROSE: Cold Fusion, AUDIO: Cold Fusion)

Biography
After Patience was widowed by Omega, she became the Doctor's tutor, just as she had been his grandfather's tutor and his father's tutor. They fell in love and had thirteen children.

Patience remembered this incarnation newly regenerated, before his hands had even touched her body. He was taller and hairier than his previous, beardless body. He had a blond curly head and a beard which was much coarser. He considered himself old. At this time, his firstborn was soon to become a father.

It was this incarnation who was present at the birth of his granddaughter, Susan Foreman. During this time, riots erupted throughout the Capitol, and the Doctor fled to his home. He also witnessed the culling of his twelve children by the then Lord President. To protect his wife he took Patience to the Machine for safety. It crashed on an ice planet, found by human colonists in the 26th century.

The explorer was honoured among the Time Lords of the Doctor's time, but they had forgotten his true name; however, the Seventh Doctor recognised it. (PROSE: Cold Fusion)
