The United States conducted many nuclear tests in the Marshall Islands up until the early 1960s.  It was during one of these tests that Bianca Wharton's father and three other scientists were caught by an early eruption.  They were bathed in radiation and despite the best efforts of the medical personnel on the island as well as back in California, all four men showed signs of radiation poisoning and later cancer.  Edward Dobson, Bianca's father, took his pension and moved with his young wife, Catherine, to Perth, Australia.  They both knew he had only a few years to live, but they were happy to live out their lives in Australia, far from the complications of their old life.  Edward continued to work as a scientist but tended towards eccentricity as the cancer spread.

Miraculously, Catherine became pregnant despite the medical opinion that Edward was sterile.  As Edward deteriorated physically, Catherine blossomed.  It seemed like some kind of grand design and both parents accepted the impossibility of their situation with grace and awe.  Bianca was born in November 1961, just three weeks after Edward lost his battle with cancer.  She grew up in the suburbs of Perth and never learned the true history of her father.  Catherine was content to raise her child without any mention of Edward apart from the fact that he was a brilliant scientist.  Bianca found herself living with an invisible presence in the house and Catherine never could give her daughter the attention she dearly wanted to.  Edward's death and the coincidence of Bianca's birth drove Catherine into depression.  Bianca was a bright spark and the more she shone academically and socially, the more Catherine seemed to fade.

Bianca showed signs of strange powers during her adolescence and her father's accidental poisoning in the Marshall Islands was discovered to be the cause.  Somehow he had passed on the unpredictable elements of the radiation to his daughter which triggered her ubergene.  She was one of Australia's only super heroes during the late 1970s and in 1981 she faced off against the nuclear-powered Warhead in Sydney as a twenty year old college student.  She kept her identity secret at first and studied medicine while also fighting crime in and around Sydney as 'Cyclone'.

When the Sentinels were recruiting for a new incarnation in 1982, Cyclone was accepted into the team and she took the opportunity to change her name to Fremantle Doctor.  As she was now to work on the world stage she wanted a name which would show her ties to Australia, and more importantly to Perth.  She completed her medical studies while a member of the international super hero team, managing to gain exciting field experience as well as advice from medical experts from around the world.

One of her first missions as a Sentinel was to oppose Warhead again, only this time he had gathered together a team of dangerous uber-criminals.  Despite being a rookie, the Fremantle Doctor was the one who stopped Warhead from breaching an experimental nuclear reactor in Sweden.  Her bravery and determination earned her popularity across the world and she would later take on the deputy leadership role in the Sentinels.  While still being an active member of the team, in 1984 she married an Australian scientist, Laird Wharton, and later that year took a temporary leave of absence to give birth to her son, Hamish.  She returned to duty as a part-time member the same year, but was only involved in missions which required her expertise in weather control.  She had another son, Edward, in 1986 and seemed to drift away from the team to spend more time with her family in Perth.

The Doctor returned to the world stage in an impressive rescue mission in 1996 when she was involved in the rescue of American senators from a CLAW death-trap.  Her return was met with widespread support and she convinced her husband that her place was with the Sentinels.  Laird left his work to look after the boys and the Doctor returned to active duty, quickly assuming the deputy leadership role again.  She became the temporary leader of the Sentinels in 2000 for a year and then in 2003 became the leader in her own right when the previous leader stood down due to the disastrous battle with First Strike in Europe.

Her husband currently works in Perth as a director of the local Southern Cross International research facility.  Her eldest son, Hamish, is a school teacher and her youngest son, Edward, has just entered the police force in Perth.  Hamish and his wife, Rachel, are expecting their first child - something which both amazes and terrifies the Fremantle Doctor.

The Doctor is a veteran super hero as well as being a professional medical doctor and international diplomat.  She is confident and honourable as has been idealised as the embodiment of Australian heroism receiving numerous awards and commendations.  Her confidence, however, can border on overconfidence, particularly when she is facing uberhuman villains.  When it comes to the threats of nature and the world around her, the Doctor is level-headed and supremely capable; but when the adversary is dressed up in a costume and threatening the world, she just doesn't seem to be able to take them as seriously.  She has nearly gotten herself killed several times because she has failed to see the real threat of opponents such as Warhead and First Strike.

She is a leader and commands the respect of the world's greatest superhero team.  She is able to speak with world leaders as equals and exercises her voice whenever she feels an injustice has occurred.  Her commitment to the Sentinels has, at times, caused conflict with her home life and she has experienced the heartache of watching villains use her family to get to her.  Her professionalism won't allow her to be blackmailed, though, and her husband has had to suffer tremendously at the hands of the Doctor's enemies - most gruesomely in 1996 when he was captured and tortured by Arctic Fox.  Their relationship is solid, although it has lost its passion as Bianca turns more and more towards her duties as the Doctor and Laird focuses on his work with Southern Cross International.

"You'd think heroes like us have been around for a long time, but really, our lives are nothing against the immensity of mother nature.  The storms, the currents and the turning of the seasons are the real power of our planet.  The rest is just window dressing and work with mirrors."

The Fremantle Doctor is a very powerful uberhuman, able to manipulate the world's weather in a variety of ways.  She is able to generate powerful gusts of wind which can batter opponents or propel her and others through the air.  She is able to use the winds to lift objects or induce temperature fluctuations.  She is able to generate other weather phenomenon such as snow, heatwaves, rain and thunderstorms.  Her most devastating attack is to call down lightning bolts, although she rarely uses these unless the odds are very much stacked against her.

The Doctor's powers are affected by solar radiation which interferes with her fine control over the weather, as well as managing to pierce her protective winds.  It is hypothesised that her father's exposure to nuclear radiation in the Pacific coupled with his later work in solar radiation contributed to this Achilles' Heel.

Bianca is a woman in her forties although she appears younger, partly because of her bright blue eyes and partly because of her regular and intensive physical workouts.  She has been a hero for twenty years or so and has decided to maintain her 'super hero' exercise and training regime while some of her contemporaries have retired from the world stage.  She is lean and healthy, not having had even a cold in the past ten years.  Her husband often jokes about her 'Peter Pan' complex: something she only partly dismisses.

Her costume consists of a black bodysuit with short sleeves, black glove and a white sash around her waist.  She wears her hair short now, although in her earlier days she often wore her hair to shoulder-length and generally tied back in a pony tail.
