A/N: Mirage is an interesting character to say the least, and no one's sure of her past. So here's a summery of how it may have been. One-shot, possibly two-shot if I decide to write for what happens later.
Disclaimer: I don't own the Incredibles or Mirage.
Average Super
Mirage's life had been hard before Buddy Pine gave her a job, her mother had died when she was eight (three years after the supers went into hiding) and her father didn't care about her. She'd always had to work, legally and not so legally, just to feed herself and pay for school supplies and things. On more then one occasion she'd had to pay the heating bill with her own money, and more often then not her money went towards buying her dad's alcohol. The young woman, needless to say, had gotten out quick and graduated high school at the age of fifteen. She went straight into college and never looked back on her childhood- Because even before her mother died, she'd had no childhood.
In college things had been worse then at home, the classes were tougher and she had to work everyday she could in order to pay for her classes. Then the unthinkable had happened, her boyfriend got her pregnant and split. She took out loans to pay for her continued education and continued to work and go to school up until her daughter was born. Weighing in at only six pounds, eleven ounces her baby was on the small side. Mirage had gotten herself deep in debt, she didn't mind though, she couldn't have cared because she knew the moment she saw her little Ann that she was going to be a wonderful mother because her baby was a wonderful baby. Ann was worth it. Ann made her life worth living.
But her joy was not to last, because six months later she was burying her little angel. The doctors said it had been sudden infant death, completely unexplainable, and that nothing could've prevented it. Mirage spiraled into depression, the death of her baby and what happened after taught her just how horrible the world really was. She tried to move on with her life, but she couldn't. She just couldn't.
Her life didn't start moving again until Buddy came into it, he made her happy. He sympathized with her views on the world. He made her forget. For two years she worked for him, until she was twenty, when his plans to become a super became a reality. When Mr. Incredible was on their island, and she received confirmation that the jet, carrying Mrs. Incredible and her children, had been destroyed. Then she remembered, she remembered how cruel life had been to her and she realized that all Buddy and her were doing was ruining other peoples lives. And she realized that she no longer wanted to work for him, that it was people like him who didn't really understand the world and who screwed it up even more.
From that point on Mirage jumped at the chance to help the Incredibles or at least hinder Syndrome. When it was all over and done with, she still didn't know what she was going to do with her life. She was still young, only twenty, and despite her past her future looked strangely bright. Buddy Pine was gone, her father was gone, and while the pain of her baby's death would stay with her for the rest of her life, she knew things were getting better. Her first act as a free woman, free from the evil which was Syndrome, was leaving the island. Mirage was going to live her life as she'd always hoped, by working for the people. By making the world a better place, one action at a time.
