A/N – Before I begin there are a few things I would like to say. The first is that this is an Alternate Universe. Things are going to be different from both universes, so don't tell me that something should be this way, or needs to be that way. Secondly, this story will be FemSlash, don't like, don't read. Finally, this story contains FemHarry, Pamela Lillian Isley, formerly Potter, and is a wrong-boy-who-lived story. This goes back to the story being AU. Obviously, Ivy's back-story in this will be different from the comics, cartoons, and movie. Once more, please don't complain.

Now On with the story.

By the way, I don't own Harry Potter or Batman.

Chapter 1

Pamela Lillian Isley, more commonly known as Poison Ivy, sat against the wall of her specially designed cell in Arkham Asylum, contemplating how she had gotten to this point in her life.

She supposed that it had started out on that Halloween, fifteen years ago this October, when her twin brother Jason James "JJ" Potter was declared the Boy-Who-Lived. She had been too young at the time to remember the events, but she remembered growing up in the shadows, ignored by her parents as they fawned over her brother. Left to her own devices, she spent a lot of time in the family library, soaking up knowledge like a sponge.

Early on, she had developed a talent for potions, and had a keen interest in herbology and botany in general.

From the time she could stand, she had brewed potions, her parents ignoring the obvious danger to her as they were too busy with her brother to even notice. Only the family house-elves payed her any mind, helping her get ingredients and ensuring her safety as best they could. But even they couldn't protect her from her own brother.

JJ had been goofing off, as usual, and she had been working on a new potion. It was her own invention, and was meant to make the plants it was sprayed on more resilient, and healthy. She had been so engrossed in her work, that she had never noticed her brother enter her potion lab until he knocked her into the newly finished potion.

It hadn't been meant for people. And as she fell into the cauldron, knocking it over and soaking her skin, she also ingested it.

JJ never even noticed what had happened as he left the room.

Mipsy, one of the family house-elves, had tried to help her. When, after alerting them, her parents did nothing, Mipsy had taken her to the only other person she thought could help the young seven year old, Potion Master Severus Snape.

To say her mother's old friend was furious was an understatement. He didn't understand how his once kindhearted, if temperamental, friend could ignore what had happened to her own daughter. He had done his best to help Pamela, but the magic of the potion had already done it's job.

There was nothing he could do.

Overnight, her young body grew to that of a woman in the prime of her life and gained it's current plant like attributes. Overnight she gained the powers that she now had. When morning came, she was no longer the seven-year old twin of the Boy-Who-Lived, but a fully grown women, with the knowledge of a seven year old.

Luckily, Severus had helped her. It wasn't hard, as she had also matured in attitude. But she didn't know a lot of the things adults needed to. Severus, as an accomplished legilimancer, was able to...implant, the years of knowledge she needed in her mind. Of course the side effect was that she learned a lot about Severus himself, along with Pomona Sprout, who had, after Severus explanation, also helped her.

It was through that process that she learned lessons of magic and life. And after a year in practice, Snape helped her change her identity, though she kept her first two names.

And thus Pamela Lillian Potter became Pamela Lillian Isley.

She had left then, going to America to study muggle botany, specifically botanical biochemistry. She earned her doctorate within two more years, before agreeing to work with Dr. Jason Woodrue.

When he tried to kill her two months later, she snapped.

That was when she killed the good doctor, and moved across the country to Gotham City. At this time, she felt more for the plants she could hear and talk too than humanity, aside from Snape and Sprout, who were more like her mentors, they were her only friends. And when they were threatened, she reacted...violently.

Hence why she had become Poison Ivy.

And in the eight years since her accident, five as Poison Ivy, she had never aged. She wondered if she would, eventually, or if she would forever remain in her prime unless killed. But neither option really mattered to her, both had their plus sides, and their minuses.

Sighing, she began to plan of a way to escape Arkham once more, without magic. That was a secret she preferred to keep under wraps.


Severus Snape hated the Order of the Phoenix, mainly because it was full of people he hated.

At the top of his list was Dumbledore, who also happened to be the leader of the "secret" organization. The man who had, not only blackmailed him into being a spy, but allowed the travesty that was Pamela Potter to happen. It was he who declared Jason, there was no way in hell he would call the spoiled brat JJ, the-boy-who-lived, and filled Lily and James heads with focusing on their son at the cost of their daughter.

Then there were the Potters themselves. He and James had never gotten along, but he had thought better of Lily. That she had basically ignored her daughter told him the woman he had once loved was dead, replaced with the bitch he currently thought of her as. And JJ, the arrogant, spoiled, brat that only passed his classes because Dumbledore would use "Headmaster's Judgment" to change the grades.

JJ's friend Ron should currently be in Azkaban. Seeing as he had, albeit unintentionally, but remorselessly, sent a young girl to her death. His insults to one Hermione Granger had sent her in tears to a girl's bathroom, the night a Troll was let into the castle. Due to the vast number of students, she wasn't noticed missing until they had been returned to their common rooms, by which time, it was too late. He, McGonagall, and...Quirrel, had come across the troll leaving the bathroom, leaving her broken body behind it.

The only reason Minerva hadn't resigned from her post then and there was his own assurances that she had done the best she could, setting out looking for her as soon as she realized the girl was missing. But the experience had shaken up the Deputy Headmistress, and Dumbledore's refusal to punish Ron for the words that had sent the young Gryffindor to her death had been too much for her. She had resigned on the spot, and James Potter had become the new transfiguration teacher and head of Gryffindor.

Then there was Sirius Black, the man who had tried to kill him by sending him after a werewolf on a full moon, at fifteen years old.

The aforementioned werewolf, Remus Lupin, was tolerable, only because he was at least somewhat repentant for what happened in their school days. But the two would never be friends. Snape may forgive, but he had never forgotten the torment Remus helped cause him.

Lastly, there was Arthur and Molly Weasley. Arthur wouldn't be so bad, if he actually care to research and experience the subject (Muggles) he was professed to be an expert in. And Molly, she was an overbearing harpy. A housewife who thought she knew all.

In fact, were it not for Dumbledore's blackmail, and the desire that, at the very least, Pamela's ostracism not be be in vain, he wouldn't be here.

The fact that he had learned the disturbing truth that it was Pamela that had stopped Voldemort and not her brother only fueled his desire to see the bastard that was once his master die, preferably for good this time. And as Dumbledore droned on about nothing useful, he waited for Dumbledore to relay this information to the Order.

"Finally," Albus said, after thirty minutes of dribble, "it has come to my attention that Voldemort believes that it was Pamela that stopped him, not JJ." He held up his hand for silence at the various outburst this statement caused, the loudest being JJ. "As I said, he believes Pamela to be the cause of his first fall. This is beneficial for us, as it will allow us time to work against him as he tries to track her down. That said, the girl is in danger, if she is still alive. We must find out where she is, or if she is even alive, before Voldemort does, for her own protection."

There were various nods of agreement around the room, everyone knew how Pamela had run off, jealous of her brother. Frankly, Snape was disgusted.

And as Lily went on about finding her 'poor baby girl,' he wondered why she couldn't have shown, even this false fear, when Pamela had first come to him.


After the meeting had concluded, Albus asked Snape to meet him back at his office in Hogwarts.

Stepping out of the floor and into the lavish office, Snape held back a sneer of disgust. Just why the bloody hell did a Headmaster of a School need such extravagant luxuries, or such bad taste in colors.

"Ah Severus," Albus greeted cheerfully. "Please take a seat, we have much to discuss."

"Indeed," Snape agreed, as he sat on the edge of a chair. "Such as why you told the Order that the Dark Lord believes Pamela to be the one that vanquished him fifteen years ago. He showed me, and all his Deatheaters, his own memory of that night. It was Pamela that stopped him, not that arrogant brat of Potters."

Albus raised an eyebrow. "I know, and have for some time that Pamela is The-Girl-Who-Lived. I have never told you the full prophecy that you heard that night." Standing up, he made his way to his pensive. As he walked he said, "I notice that you don't comment that Pamela is also Potter's...brat, as you so eloquently put it."

Severus sat straighter in his chair, on alert, but said nothing, and it seemed Dumbledore was willing to let the subject drop.

The headmaster tapped the side of his pensive with his wand, and the form of Sybill Trelawney rose from the liquid memories and began to speak, in a voice that haunted Severus' dreams.

"The one with power to vanquish the Dark Lord approaches...born to those who have thrice defied him, born as the seventh month dies..."

Snape closed his eyes as he heard the part of the prophecy he had that faithful night, and wished, not for the first time, that he hadn't. What Trelawney spoke next would be new to him however.

"And the Dark Lord will mark her as his equal, but she will have a power the Dark Lord knows not...and either must die at the hand of the other for neither can live while the other survives...the one with the power to vanquish the Dark Lord will be born as the seventh month dies..."

Snape's eyes sharpened angrily. "You knew," he accused, his soft voice full of anger. "You've known all along that Pamela stopped him that night. Why did you declare JJ The-Boy-Who-Lived then? Why did you make Pamela's life a living hell while she under Potter's roof?" he demanded.

"I did what needed to be done Severus," Albus informed him. "We needed a savior to look to, yet we needed a hero for the future, one not concerned with fame or glory. A hero that would do what needed to be done because it was the right thing to do. So I declared her brother The-Boy-Who-Lived, and planted into Lily and James minds, the idea to ignore Pamela."

Severus was incensed, and were it not for the numerous oaths he had sworn to Albus, would have pulled his wand on the old wizard. It seemed that he had, not only ruined Pamela's life, but Lily and JJ's as well. He cared little for James, but if the suggestion was ever removed and Lily realized what had happened, she would be devastated. "You bastard. HOW DARE..."

"DO NOT TAKE THAT TONE WITH ME, SEVERUS SNAPE!" Dumbledore bellowed, his voice laced with magic. And for this brief moment, Severus could see why Voldemort feared this seemingly harmless, and possibly crazy, old man. "I have done what was needed. And now, we must find Pamela," he informed the potions master. "She is the only one that can defeat Voldemort once and for all, no one else."

Snape clenched his fist. He was angry at the situation he was now in. Either he protected Pamela and kept her location to himself, risking that no one else could stop Voldemort, or he told Dumbledore, and Pamela was dragged back to England, and he had no illusions that that was exactly what Albus would do.

Either way, he failed in his duty.

Before I hear a rant about another story, I want to say that I've had this idea swimming around my head for months, before planning it out and starting it. And I originally intended to keep it on my computer and not post it yet, as there are a couple other stories I am working on that I'm doing that with. But I really, Really, REALLY, want to see how this first chapter is received.

That said, the poll on my profile is closed, and I will be trying to work on White Owl the most, though whether I actually can keep my focus on it remains to be seen.
