Bio: Jackpot gained her powers through a lab accident involving gene experiments.
She joined the Initiative training program, becoming a licensed hero, only to decide she didn't want to be a super hero.
She eventually sold her license and the Jackpot identity to Alana Jobson, a girl powerless until she took MGH to enhance her abilities.
When Alan Jobson died, Spider-Man confronted Sara and convinced her that it was her responsibility to resume the identity of Jackpot, and to use the abilities she had been given.
