Character Evolution
Earth-9
There are many stories about her origins but the three most popular are:
1.) The first is that she was the murdered adventurer and archaeologist Lois Lane, her body dumped in the Atlantic where Florida used to be. It is unknown what happened next, some say she was found by mermaids or maybe angels, but either way those who died there brought her back to life and gave her the abilities she currently possesses.
2.) The second one insists that a pair of twin sisters one good and one evil fought a battle over mystical powers. The good sister won and placed the mystical power in the lantern, and then she dedicated herself to fighting that which made those dead suffer.
3.) The third one says that she was the sorceress Zatanna, who was sent on a mission by the Dark Circle of Magicians to find the lantern. After many years when she finally did find it, the pirate Jason Blood who had the lantern for centuries simply gave it to her.

When Superman took control of the world, the Green Lantern continued her duties much as she always had. However, as a side-effect of the events of Infinite Crisis, (and the re-emergence of the Earth-97 lantern) her lantern was lost, and she began to age at an enhanced rate. As she lost her magic powers, she was forced to resort to begging to feed herself, and her fellow heroes lost faith in her judgment.
Lantern Returned
However when Lia Nelson was trapped on New Earth, she used the lantern to return to Earth-9. The lantern reappeared in the Green Lantern’s custodial graveyard. Revitalized by the lantern, she regained her former powers. Now she plans to enlist Wally West and John Stewart of New Earth in her plans to reconnect with the Secret Six .
