- If anyone is a mistress of death, child, it is me... Hush. I sense death walking.
- — Jeannette src
Jeannette was born centuries ago into a tenuous lineage of Hungarian nobility. Noble but poor, her family sold its belongings so that it could send her at the age of nine to the Castle Csejtein order for her to serve Countess Bathory and learn the ways of the court. What no one outside the castle realized was that Countess Bathory was perhaps the most horrific female serial killer of all time. Jeannette was forced to watch as the Countess and her four assistants horribly tortured, mutilated and killed young girl after young girl. The horror was so great, Jeannette lost the ability to speak. She was told that she was the favorite and would therefore being saved for last. Eventually, the Countess and her assistants were tried and punished. Jeannette managed to have herself remain the Countess' servant to care for the dark lady while she spent the rest of her days locked away in a room, bringing meals and removing the waste. But the truth of it was Jeannette sprinkled tiny quantities of broken glass into every meal.
The process took years, but soon Countess Bathory could not experience even a day without pain. Medical attention was denied, and she went mad from the endless torture Jeannette inflicted upon her. Jeannette died by the blade of an executioner's axe for reasons unknown. She paid off the executioner with her mother's necklace, the only piece of jewelry she had left. This was to ensure the executioner would make it quick, but he did not. The first three swings of his axe missed their mark, cracking and breaking her body without killing her. The horrible trauma of this caused her to lose touch with herself and who she had been. She found and became the Banshee.
Centuries later, Jeannette was still very much alive and running a Las Vegas hotel-casino known as Nocturne. She had acquired for herself a large and loyal staff, very much like her own private army. But this life must have begun to bore her. She took up an offer from an old friend, Scandal Savage, to join the Secret Six and help them on their job to deliver the Get Out of Hell Free Card to Gotham City. She housed the team at Nocturne when the arrived in Las Vegas, helping to protect them from the horde of super villains after the bounties on their heads. Then, she left with them for Gotham. Along the way, Jeannette made her sexual intentions towards Deadshot very clear. She cornered him in a rest stop restroom, telling him the story of her past with Countess Bathory as she began to have her way with him; however, he shot her. This was the beginning of Deadshot's plan to take the card and bring it to Gotham City on his own. But being shot was only a small bother to Jeannette.
Despite the shooting, Jeannette continued to pursue Deadshot. He reeked of death, and this turned her on. Things progressed between them after she forced him into a double date with Scandal Savage and Liana Kerzner. From this point on, they were in something resembling a relationship - or at the very least, they were having regular sex. She informed Deadshot that he reminded her a great deal of her first husband, a man who hid behind money and being a soldier as an excuse for all of his killing. She loved him, and she threw him to his death; Deadshot looked very much like him.
Tensions rose in the Secret Six after taking a protection job over a prison being constructed by slavers, especially when it was revealed that the Amazon known as Artemis was one of the slaves. Jeannette had a great dislike of Amazons, but disliked even more the idea of these men having Artemis as their slave. She snuck into Artemis' cell during the night and freed the Amazon, only to be discovered by the rest of the Six. The team split on what should be done, whether to do the job as they agreed or free Artemis. Deadshot came down on the side of doing the job and shot Jeannette, again. Catman and Ragdoll also came down on the side of doing the job, while Bane and Scandal sided with Jeannette.
Wonder Woman's arrival forced a pause in the Six's disagree. Artemis appeared dead, and Wonder Woman wanted answers. Jeannette, however, was not so willing to cooperate. The two fought, with Jeannette taking a brutal beating from Wonder Woman until transforming into her banshee form and unleashing her terrible scream. The horrors of her wail were enough to fell Wonder Woman, while Jeannette almost lost herself to her banshee form. Scandal was able to talk her back to her normal self. She was carried off by Scandal Savage, and was joined by Bane, who carried Artemis. Jeannette soon recovered some semblance of her sanity and took part in helping the rest of the imprisoned Amazons escape. She and Catman were attacked by Mr. Smyth's fierce assistant, who was in fact an Amazon herself. A cut to Jeannette's neck caused her to lose grip on her mind once again as she began flashing back to her beheading. She and Catman were saved by Deadshot, who put a bullet in the Amazon's head. In the aftermath of this job, she supported Bane's decision to take over leadership of the Secret Six.
