Fan Casting The Flash in Batman Beyond Animated Movie Series

The Flash of the future, a member of the Justice League Unlimited who communicates with previous Flashes through the Speed Force. In the 2040s, Danica Williams lived with her mother and father. Her father was a transportation engineer at S.T.A.R. Labs who studied meta-human technology in an attempt to integrate it for everyday use. She and her parents jumped from town to town, helping to improve the transportation system. At one point, they lived in San Francisco, and at another, in Gotham City. However, they quickly moved out of Gotham as a result of the crime rate, at last settling permanently in Central City. Although Dani had lofty goals of being a track star, she had complications that limited her physical exertion. She was diagnosed with multiple conditions before the doctors finally settled on asthma, and she was prescribed an inhaler. In addition, she was thought to have some form of mental illness as she often spoke to figures nobody else could see or hear. As it turned out, she was communicating via the Speed Force to figures who took on the mantle of The Flash. One day, she was urged by the voices to save a man from a train. It was then that she discovered she could run at an incredible speed and managed to save the man's life. Dani learned her way around her newfound powers quickly, even mastering the ability to run on air molecules within hours of discovering her powers. This impressed even Impulse, the most skeptical of the voices, who himself was never able to master this ability. Dani used her inhaler to protect her identity as the newest Flash. That summer, every Flash up to that point trained her in the Speed Force. She also took up training with a parkour group. She eventually came clean to her parents, showing them her abilities, and her father designed a suit that would enable her abilities while also protecting her from harm.
