Frances Kane was a childhood friend of Wally West, and found herself the recipient of magnetic powers that made her an anchor for Neil Emerson aka the supervillain Doctor Polaris, himself exiled in another dimension trying to return to his native Earth-One. This led to a conflict with the New Teen Titans.
Ann Hunt was a movie actress whom a time-displaced Knodar mistook for 23rd century villainess the Black-Eyed Bandit. Enlisting her aid against her will in stealing precious golden keys from Gotham City on Earth-Two, he once more faced his recurring adversary Green Lantern.
Somehow Frances' body gave her the natural gift to store such energies naturally, and she would aid the Titans a time or two in the future. In an alternate timeline, she'd become the heroine Magenta.
Ann played the part given her to perfection, and stole Knodar's magnetic metal controlling device from him in order to shackle the villain and free Green Lantern and his pal Doiby Dickles. After Knodar was taken back to the 24th century for imprisonment, Hunt resumed her acting career.
