Abby always knew she was adopted. No one in her family had blue eyes or black hair, or any trace of an English accent. Problem was, her parents always denied it, but it was never discussed. The other kids knew too, but they accepted Abby as family, so much so that she was even the bridesmaid at her sister's wedding at fourteen. They also knew Abby was different when her abilities started to manifest themselves. Everyone in the family did what they could to keep her talents under wraps, but did not discourage them either, providing she used discretion. Sadly, discretion is not in a fourteen year old's vocabulary, especially less than six months after being forced to move with her parents out of Brisby Flats and away from all her friends.

Abby was free spirited and reckless to a fault as soon as her powers began to appear. Within two weeks, her parents were in her doorway and turned her television to a news story about CSPD pursuing a flying mutant that when they finally had cornered, then loose with an electrical storm and then disappeared. The giggle that escaped Abby confirmed their suspicions and a long talk followed that eventually ended with them telling her what little they knew. Within days of Wendy having a miscarraige after being a victim of a car crash during a police chase, a basket with a crying Abby had appeared on their balcony. With no way to return the infant and knowing that no one would ever beleive them, so they raised her as the daughter they had lost. They did not even know her birth name, and the only thing they had to connect with her birth parents was an ornate dagger. Abby was upset, but releived to know as much of the truth as she could find out. She looked at the blade, and decided her parents should keep it safe for now. The problem was, the mischief did not stop.

it wasn't until Abby was seventeen that her misuse of her powers came back to haunt her. A color gang  she had harassed managed to track her down, and Abby returned home to find ambulances and police cars outside her home. The gang had invaded the house, and both her parents had been seriously wounded. outraged, and riddled with guilt, Abby dressed herself up in black clothes and sunglasses and hunted down the colour gang's hangout. End result, eleven punks in the hospital with serious injuries and electrical burns AFTER they admitted to being responsible for the home invasion. When questioned, they couldn't describe the person responsible for their downfall, except a flying female ninja that could shoot lightning bolts from her hands, who called herself Arc.

Abby felt good about helping clean up her neighbourhood, and decided to continue under her new Arc guise. Within six months, the vigilante had crime in a ten square block under control, though was smart enough to lay low when real heroes or villains came around, either to recruit or deal with the upstart. She did have one bad habit, she was not above helping herself to her target's wallets, which she put to good use supporting her parents and herself. Mom and Dad did not approve, but as tight as things were, they did not try to stop her.

Then she received a call unlike any other....
