The Queen of Fables' was originally a sorceress from another dimension until she was exiled to Earth. She reigned until princess Snow White defied her and she was trapped in the Book of Fables. Snow White used the book to turn fact into fiction and undo all the Queen's terrible acts.

Countless generations later the Queen was unwittingly released from her prison. She transformed Manhattan into an enchanted forest full of fantastic creatures extracted from folk tales. Just after being released she attempted to locate Snow White, mistaking a television for a magic mirror, and ordered it to show her -"The Fairest In The Land." Coincidentally, the TV was currently showing the news, reporting the Justice League's latest battle, and at that moment showing Wonder Woman. Believing the Amazon Princess to be her daughter, she confronts her, forcing her into a deep sleep in an enchanted forest. Aquaman awakens Wonder Woman with his kiss (as he was once a Prince, and is now the King of Atlantis, it counts as a kiss from a Prince), and Batman discovers the book that the Queen had been trapped in. Eventually, the Justice League managed to stop her, by making her realize that she was no longer immortal and eternally beautiful in the real world, and lock her up once more (by trapping her within a book on the United States Tax Code, where she could find nothing imaginative to use as a weapon), undoing her spell again.
