During a week-long scientific retreat in Bern, three geniuses met together to discuss the future of the world over several bottles of exquisite wine. They were three of the brightest intellects but already it was clear that each was on a very individual path. Saul Numen was the idealist, and would go on to become the leader of the New Men, long considered the First Family of the Uberworld. Akello Lwanga was the pessimist, and following his destiny would become the dictator of Azambia as Witch Doctor, a fusion of technology and mysticism. And Gulla Gísladóttir was the mischievous one, the girl who loved science because of its secrets. Her curiosity would help her break through extradimensional barriers and become the sophisticated super villain Arctic Fox.

She began her criminal career to finance her research, fiddling the books where she could; but when she did manage to crack through the dimensional walls she found that she could simply walk through one dimension and pop out in ours again. It was simple to fine tune her primitive portals so that she could appear inside bank vaults and then out again. Once the money came pouring in her research seemed to expand exponentially. She attracted interest from Zodiac and CLAW but shunned both of them to remain independent. She had everything she needed - they couldn't offer her anything she didn't already have access to.

While no one really connected Arctic Fox to Gulla Gísladóttir she managed to continue living two lives. Her expertise in dimensional physics led her to work closely with Saul Numen and the New Men on several dimension-hopping adventures. It was during a trip to Asgard that Gulla found herself attracted to her long-time friend, but the presence of his wife, Chloe, seemed to put a dampener on the potential romance. Gulla slipped away from the New Men and met with a posse of disgruntled dwarves who agreed to attempt to kill or kidnap Chloe Numen. Although it wasn't exactly a success, Gulla did get a taste for targeted villainy.

When she returned to Earth she decided to expand her horizons and move away from the traditional bank robbery. Arctic Fox began to target technology depots such as SAGE and Southern Cross where she managed to escape with secret weapons and devices which added to her growing arsenal. She even challenged heroes such as the Brigadier of Knightwatch and Iron Amir of the Five Pillars. In these contests she always had an intricate plan which resulted in the hero being trapped in one of her dimensions fighting against the clock and usually a horde of angry residents. She never really considered killing her opponents until she was locked in a deadly struggle with the muscle-bound hero Beowulf. When she realised she was captured and would likely face a long time in prison, she didn't even hesitate before ripping the hero in two with a well-placed Dimensional Portal.

With Beowulf's blood on her hands, Arctic Fox suddenly became infamous across the globe. She was contacted by CLAW again and offered several high-paying jobs, which she found that she accepted - not because of the money but because of the prestige. She had discovered that having a reputation was almost as good as having a limitless supply of cash.

Arctic Fox continued to run riot across the globe and teamed up with former celebrity bodyguard Avast, most famously when they attempted to rob casinos in Monte Carlo. Later she was approached by Nepatiabet and somehow found herself organising a supervillain team which Nepatiabet dubbed First Strike.

Arctic Fox found that she enjoyed the company of her team mates and has mostly continued as a team player, although she is always the one who calls the shots. She has especially enjoyed the flexibility a team brings when opposing other uberhuman teams such as the New Men and the Sentinels.

Gulla is in complete control of everything. Not only has she shattered the logic which had long since kept dimensions apart, she has also formed one of the world's most powerful super villain teams. Her work gives her pleasure, especially the intricacies of planning and execution. She enjoys a test of intellects almost as much as she loves the thrill of exchanging attacks in a full-blown uberhuman brawl.

Her discoveries enable her to traverse various dimensions, and Gulla often moves through the ones she is familiar with as a way of collecting her thoughts or relaxing. She usually travels alone, unless it is business. There are several dimensions she would never allow anyone else to experience and these places are perhaps the true reflection of her soul. They are peaceful, uninhabited and beautiful places of scintillating cloud formations or secluded glades.

The rivalry between Arctic Fox, New Man and Witch Doctor has endured through the years, and although the three can often work well together on projects they are usually in competition with each other, keen to show the others how wrong they are in some area of science or philosophy. Arctic Fox has also developed a keen dislike for Chloe Numen who has managed to usurp her plans on more than one occasion, as well as being the wife of perhaps the only man who could keep Gulla happy. The two women share a strong enmity for each other, something which often leaves Saul baffled.

"You'll never catch me, because where I'm going, you cannot follow. Ta-ta!"

Sentinels Report (extract): "When the Arctic Fox is involved, you only ever see the surface of her plans."

Arctic Fox is generally able to put her hand on any of her gadgets in a split second, as she maintains thousands of pocket universes as storage sites. She simply has to dip her hand into one of her pockets which serves as a small portal and she has access to any number of inventions and stolen or adapted technology.

Some of her favourite gadgets include: arctic razors (throwing blades), a wicked looking bowie knife, an extradimensional deflector shield which is capable of resisting almost all forms of energy and projectiles, a heavy blaster of alien origin, an umbral slime projector which releases a sticky black substance and covers a target in what can be described as a second skin, and her trademark dimensional portals which enable her to travel across great distances on Earth and between dimensions. Her range varies but she has managed to travel easily between Iceland and North America.

Like all members of First Strike she wears a communicator which has a standard channel and a encrypted one. She also wears snow goggles which include flash reduction, and her costume is insulated against the cold.

Arctic Fox wears a silver-grey bodysuit with a quilted vest and thick-soled boots (to make her appear taller). Her light blonde hair is generally tied back in a pony tail and mostly covered by her half helmet and snow goggles. She wears a belt studded with square cases which are actually portals into several dimensions she has claimed as her 'storage dimensions'. Although they appear small, they can accommodate very large items and when she draws them out they grow to their normal size as they enter the Earth Dimension.

Out of costume Arctic Fox wears expensive clothing or a more or less conservative cut.
