Biography
Before meeting the the Doctor, Sharon lived in the northern English city of Blackcastle, a steel mining town. Her best friend on Earth was schoolmate Fudge Higgins. She met the Doctor when Beep the Meep crashed his spacecraft in Blackcastle and sucked the whole city into a black hole. Under the mental influence of his black light radiation, she tried to kill the Doctor. She accepted an invitation to travel with the Doctor after he had returned everyone else home.

Travels with the Doctor took her aboard the Space Hog, an astrofighter in the New Earth System, which was attacked by the Werelox and their masters, the Daleks. (DWM: Doctor Who and the Dogs of Doom)

Sharon experienced a retinal implant viddy machine education (on Galactic Crime-Fighting rather than advanced high school physics as the Doctor had intended) while onboard the Doctor's TARDIS. A new, more mature hair style was nothing compared to suddenly aging four years when the TARDIS' chrono-compensator made everyone aboard age while passing through a time rift while escaping the evil Brimo. While this did not affect the Doctor significantly, Sharon was suddenly in her early twenties. Not having been fond of being an adolescent, however, she was quite pleased with the results.

Her adventures continued to China, 1522 AD, where stranded Sontarans were using Shaolin Monks to fight and retrieve crystals necessary to send a distress signal. (DWM: Dragon's Claw)

As the Doctor succeeded in returning Sharon home, the Doctor, K-9, Sharon and the TARDIS were caught by a teleport beam operated by the Varan Tak. They were treated as samples by the Ship, which was collecting samples of lifeforms throughout the Universe. (DWM: The Collector)

Her next journey saw her revisiting old friends of the Doctor on Unicepter IV, where she struck up a relationship with Vernor Allen, a professional dreamer who used a Slinth called Miki. When the Slinth were drained and no longer used for dreaming, Sharon decided to start a new life together with Vernor, feeling it impossible to return to Blackcastle since she had grown up.

Behind the scenes

 * Created for the Doctor Who Weekly comic strip, Sharon has the distinction of being the first recurring non-Caucasian companion of the Doctor to appear in any medium, predating Mickey Smith by decades. She is predated as a non-Caucasian character only by Nick Willard from Zeron Invasion in TV Action, who only appeared in one story. She was also the first original companion to be created for the comic strip,. Her creator, Pat Mills designed her deliberately as a nontraditional comics heroine. Mills, noticing the preponderance of dumb white rich girls as heroines, made Sharon deliberately black, poor and intelligent. Apart from K9, it would be several years before the comic strip began featuring TV companions.
 * Sharon's surname "Davies", not mentioned in Doctor Who Weekly, comes from a data file on the Doctor in the Marvel UK comic book Death's Head, starring the character of the same name.
