Sally Sonic can “turn [her] whole being to magical, super-sonic vibration.” In practice this means that she’s endowed with “supersonic strength” and attendant superhuman durability. She can also fly - this writeup assumes a supersonic speed.

Sally Sonic seems to still have some skills from her days as a teenaged sleuth.

History

Sally Smart was born in 1930, apparently in the English countryside. During the war, she had a short career as a teenaged sleuth. Sally investigated small local mysteries in the style of children’s books of that day - she was a contemporary of the earliest Famous Five novels by Enid Blyton.

Wrapping up one her cases, Sally brought back a cat kidnapped by other children to his owner. To thank her for finding her cat, the odd and elderly lady gave Sally a magical whistle. Thus was Sally Sonic born.

From 1945 to 1954, Sally had a wonderful career as a popular, magical heroine. She caught robbers in domino masks and stripped shirts, she shared adventures with the aces from the RAF, and her best friend and ally was Barnabus, the Teddy Bear King - quite literally a magical, man-sized animated teddy bear wearing a crown. Her family doctor determined she would remain eternally 15 or 16, and might be able to live forever.

Back to life, back to reality

In 1954, Sally’s parents died in a car accident - which likely was a disguised assassination. While Sally was 24, the NHS refused to believe that she wasn’t 15 (one suspects that all official documents about her had been stolen) and she was sent to a ghastly orphanage. While the upstanding Sally did her best to comply by the rules, the place was a perpetual nightmare of excessive discipline and corporeal punishment. At night, Sally Sonic would fly out to help people, but this often resulted in being punished and locked into a wardrobe for her unexplained absences.

Sally eventually cracked despite her desire to be a good girl. While locked up in the “wardrobe of solitude”, she just punched through the wall and flew out, fleeing the orphanage. She went to London, where she planned to fight crime and evil like a good super-heroine should.

There, Sally Sonic met and teamed up with fellow superhuman defender Vitaman, with whom she fell in love. However, while he had been hailed as a hero for his deeds during the war, Vitaman was really a criminal and a ruthless opportunist. He manipulated the naive Sally like pimps do, exploiting her adolescent appearance by selling her to the British underworld for pornographic shoots. During one such session, Sally Sonic was injected with the serum of evil originally developed by Dr. Jekyll.

The serum turned the goody-two-shoes, ingenuous young woman into a depraved psychotic. The triumphant Vitaman then revealed that it was the last step of his decades-long revenge plan against her father Judge Smart, a magistrate who had condemned him and his brother to ten years in prison before the war. Sally no longer cared about such things, though.

Super-porn

Knowing how much money her child-like appearance could earn her in the porn industry, Sally left for the more lucrative US market. With the large population and superhuman population, she found a position in the fetish industry about superhumans. Millions of customers were fascinated by the perfect and ageless bodies of superhumans and demonstrations of super-powers by sexually objectified women. Sally looking clearly underage and having very graphic, direct powers, she became a porn star.

Between the evil serum, and a life that had gone from the wonders of an eternal childhood to the manifestly squalid, Sally was warped inside. She wanted to hurt women who had a happy and fulfilling existence, and developed a pattern of stealing married customers away from their wives through e-mail conversations, cybersex and dates, leveraging their erotic obsessions with super-women to inflict as much harm as she could.

One of her marks was Professor Lance Harrower, a successful researcher. While his young wife was exceptionally beautiful and gifted with a super-heroine-like physique, Mr. Harrower was obsessed by how she would look when she got older and was consumed by his obsessions about eternal youth, power, fame, hard bodies and invulnerability - in short, superhumans like Sally Sonic. Through hundred of e-mails, Sally leveraged his neuroses and convinced him to try his latest research on himself in utterly unsafe conditions to gain power. Harrower died from exposure to his special compound and infected his wife, who survived and gained superhuman powers.

Girl-on-girl

Sally Sonic’s psychotic hatred focused of Mrs. Harrower. Not only was the young widow a symbol of everything that Sally hated, but as the very reluctant superhuman Bulleteer she had started investigating to find the person responsible for the death of her husband.

As “Sara Smart”, supposedly an art student who had just come from Great Britain, Sally became a lodger at Mrs. Harrower’s home. Eventually, she ambushed her and attacked.

Being far more experienced and vicious, Sally Sonic had the upper hand - especially since the Bulleteer was a gentle and sensitive woman and lacked any sort of killer instinct. However, even Sally’s great strength couldn’t genuinely damage the Bulleteer’s chromed, airbrushed metallic body. Sally Sonic ran out of HPs, and the Bulleteer mauled her with an engine block to make her stop. Scared that she may have seriously wounded her self-proclaimed nemesis, Mrs. Harrower ended up driving the unconscious Sally Sonic to the nearest hospital since no ambulance was available.

During the rush to the hospital, Sally Sonic woke up and, consumed by blind hatred, tried to wrestle the wheel away from Mrs. Harrower. This sent the car crashing, and the collision killed Sally despite the Bulleteer’s efforts.

Just like Sally Smart’s life had been wrecked solely for vengeance against her father, Sally Sonic’s death was but an instrument. Her last, enraged action was but one of the many small things that fulfilled a prophecy made several million years before she was born.

Personality

As a kid Sally Sonic had a wonderful, dream-like life. Now she is incredibly warped, bitter and neurotic and wants to destroy the lives of other women who have what will be forever denied to her - a well-adjusted, loving adult life.

Sally blames the entire world for what she has become, and refuses to accept that anybody undergoing the same horrors would not end up as warped as she is. She proves it over and over again by preying on husbands’ weaknesses to destroy wives.

Since she looks like a pretty, innocent 15 or 16-year old she is forever denied all the privileges of adulthood (she cannot even get a beer in most US bars) despite being 75. This is an additional source of senseless dissonance in her life, alienating her further as her eternal youth and seeming innocence are nothing but a curse.
