Madeline Joyce (Earth-7045)

Madeline Joyce was a wealthy teen heiress and the ward of her uncle, who was a powerful radio mogul. She met a scientist associate of her uncle, Dr. Lawson, who claimed to have invented a device that gave him superpowers when struck by lightning. Madeline played around with the device right as a thunderstorm rolled in and the device knocked her out.

The scientist saw her unconscious body and assumed that the device had killed her so he destroyed the device and committed suicide. She was not dead, though, and when she came to she had superpowers. She donned a patriotic costume and dubbed herself Miss America. She was active during World War II where she met the Whizzer, and the two fell in love.
