Kadiatu Lethbridge-Stewart

Kadiatu was the only existing prototype of a next-generation human super soldier program conducted in the years following the Thousand Day War. Kadiatu was related by adoption to an off-shoot of the Lethbridge-Stewart bloodline that arose from an affair Alistair Gordon Lethbridge-Stewart's conducted during his posting as a lieutenant in Africa, making her his great-great-granddaughter (NA: Transit).

History
Kadiatu was born in the Imogen R&D facility in Leipzig. After the project was destroyed at the behest of the underworld figure the Angel Francine, she was adopted as a 3 month old baby by the man responsible, Brigadier Yembe Lethbridge-Stewart when he found himself unable to euthanase her. She grew up in Makeni, a hick town in the West African forest, surrounded by veterans of the Thousand Day War. As a child, she was subjected to psychological supression techniques designed to minimise the expression of her ubersoldaten qualities. Around the age of 8 she was rescued from drowning by her father hauling her out of the water by her hair.

In the late 2120s, she was an engineering student at the Lunaversity, attempting to convert the complex mathematics of the Interstial Mass Transit System into a basis for functional time travel; prior to her first encounter with the Doctor she was about half a year away from establishing the theoretical basis fot a working prototype. She was eventually able to construct a primitive time craft powered by nuclear detonation as part of a corporate research project, which she promptly stole. Unknown to her, using the time craft punched holes in the fabric of space-time, creating anomalies and allowing all manner of species to move through space and time (NA: Set Piece).

In 1754 the Doctor found her in a feral state on a British slaver ship, having killed everyone on board. Sedating her, he took her to The People's Worldsphere, where he asked aM!xitsa to watch over her. He returned three months later and placed her fate in the hands of Bernice Summerfield, who decided that she could be rehabilitated instead of euthanased. Kadiatu subsequently developed safer time travel technology, becoming a temporal agent for The People, with aM!xitsa accompanying her (NA: The Also People).

Kadiatu later Bernice Summerfield and Jason Kane's wedding in 2010, where she met her adoptive ancestor Alistair Gordon Lethbridge-Stewart (NA: Happy Endings). She would later give Bernice a temporal lift to the house on Allen Road in 1997 (NA: The Dying Days).

She reunited with Bernice Summerfield for a trip to Earth in 2606 where the two women uncovered a plot involving the President of Earth. (BFBS: The Final Amendment)

Physical Characteristics
Kadiatu was tall, physically well-conditioned and dark skinned with coal-black irises. She possessed lower baseline metabolic and oxygen requirements (manifesting in slowed breathing and heart rates) that would lead to coma-like conditions in ordinary humans. Further her physical and mental reflexes were heightened along with her strength and endurance. She possessed a functional appendix, which allowed her to derive peak nutritional value from a wide variety of food stuffs. As a trade off, she would eat more frequently.

As a student she wore cotton hair extensions through which were woven data crystals and electronic counter measure devices.

Despite being the child of a military family, she received no sort of combat training but found herself responding with instinctive proficiency in unarmed combat and the use of arms. She exhibited no ethical or moral reaction to taking a life in combat.
