I decided to make a Rule 63 Harry Potter fanfic. Harry's a girl…but everyone else is the same gender. Yeah, this isn't a much different reality, is it?

Still, I don't think I'll give Mary the same personality as her male counterpart.

Why? Because while I figure this fanfic could follow the same storyline as the books, I'm not the type of person to copy and paste Harry Potter novels.

So enjoy a slightly different show.

Chapter 1: The Girl Who Lived

It was a day of rejoicing in the world of magic. And though the Muggles might not be aware of it, they had a reason to celebrate as well.

Apparently, Lord Voldemort was gone forever. He had mysteriously fallen victim to his own Avada Kedavra spell.

The Order of the Phoenix had won. Good had triumphed over evil. The light side versus the dark side. As it so often did.

However, though they had more or less achieved their ultimate goal, things were not all well for the Order of the Phoenix.

On the night Lord Voldemort met his end, Lily and James Potter both perished because of the Killing Curse.

And to make matters worse, Sirius Black had helped Lord Voldemort hunt them down and kill them. And he also killed his friend, Peter Pettigrew.

Muggles had said that Peter had blown himself up, but Cornelius Fudge (the minister) thought that Muggles were full of baloney.

Lupin had been hit especially hard, since two of his closest friends were dead, and his other closest friend…was not his friend anymore.

But on the lighter side of things, their daughter had survived.

Though she had a scar on her forehead. It looked like a lightning bolt.

Lupin didn't think it would be a good idea for him to adopt her though. He was struggling from low income. Curse Dolores Umbridge. Not that he would cast a curse on Dolores Umbridge though. He didn't want to share space with Sirius Black at all.

The other members of the Order of the Phoenix wanted to get back to their lives before joining the order, though some of them wished to search for Death Eaters hoping to continue Voldemort's cause.

Dumbledore had a solution…but it wasn't an orthodox one.

Mary Potter would be adopted by the Dursleys. Petunia Dursley was Lily Potter's sister…though unlike her sister, she couldn't use magic. Sometimes people were blessed, but sometimes magic skipped right over people. Mr. Filch knew it all too well.

"Don't the Dursleys hate magic? I met Lily's sister a few times…though I never told her I was a werewolf. I could tell she wasn't fond of me." pointed out Lupin.

"Speaking of Lily's sister, her husband has an explosive temper. And I have reason to believe he drinks." noted McGonagall.

"And their son is so fat, he takes up three Harry Potter movies!" exclaimed Mad-Eye Moody.

He pulled out three of those movies, which all had Dudley on the front cover.

"Yes, yes, but we need to keep their daughter safe from Death Eaters. It's what Lily and James would have wanted. Having her live in the wizardry world would paint an open target on her head. If we have her live in the Muggle world, Voldemort's followers would be hard-pressed to find her." noted Dumbledore.

"Can you please not say Voldemort's name? You know how much it scares me." remarked McGonagall.

"If you wish to be brave enough to face him, you have to be brave enough to say his name. Though personally I prefer calling him by his real name, Tom Riddle." remarked the man.

The Order of Phoenix members nodded.

"I suppose you have a point." nodded Minerva. It was easier than saying He-Who-Must-Not-Be-Named anyways. Or The-Wizard-That Haunts-Your-Nightmares. Or You-Know-Who. Or Azkaban-Won't-Take-Him. The list went on.

About an hour later…

"You want me to adopt a witch? You've got to be kidding me." asked Vernon incredulously.

"I suppose my sister would want that." noted Petunia.

While the two didn't normally see eye to eye, she was upset that her sister was gone.

Still, she wasn't sure about having a witch in her house.

And she wasn't sure what Dudley would think either.

Reluctantly, Vernon signed the adoption papers.

And so did Petunia.

Hopefully people wouldn't find out that their niece was a witch.

Otherwise people would think that they were weird.

Petunia knew she thought her sister was weird.

But now that she was no longer alive, she would no longer say those things.

She wasn't like Vernon's sister, that's for sure.

About ten years later…

Dudley was feeling excited. Today was going to be his eleventh birthday party.

He was going to get lots of presents. Over two dozen, in fact.

Though for some reason not a lot of people came to his birthday parties.

He didn't know why.

Suddenly, he let out a fart.

"Better out than in, I always say!" exclaimed Dudley.

Dudley Dursley was not well liked by his peers…not least due to his tendency to bully them.

"Well, I know someone who will come. Where else would she go?" asked the boy.

It wasn't like she was allowed to leave the house.

"Oh, Mary!" exclaimed Dudley.

Dudley knocked on her door.

Currently, Mary was playing a game of go fish with some spiders.

She bore a striking resemblance to her mother…but she too had her father's astigmatism…Dudley didn't know what that was (since he didn't often pay attention in school), so she explained she simply needed glasses due to her less-than-stellar eyesight.

"Got any threes?" asked one of the spiders.

"Go fish." answered Mary.

Suddenly, she heard the knocking on her door.

She answered the door for her cousin.

"Are you ready to start your birthday party?" asked Mary.

"Were you talking to the spiders again?" questioned Dudley.

"If my uncle and my aunt didn't want me to talk to them, why'd they put me in a cupboard filled with them?" questioned the bespectacled girl.

Dudley shrugged.

Unfortunately for Mary, her schoolmates thought she was kind of weird.

She didn't quite fit in with the rest of her classmates.

For example, one time her pencil began flying into the air.

Vernon poked her with an eraser afterwards. He didn't take too kindly to flying writing utensils.

"Stop poking me!" exclaimed Mary.

"If only I could erase her magic." thought her uncle.

On another occasion, her burrito swelled in size.

"I guess I'm having an extra big lunch tonight." noted Mary.

Aunt Petunia must have thought so too, because she didn't get dinner later that day.

It wasn't just at school though.

On one occasion, Petunia made her wear an itchy sweater…which Mary didn't like.

However, she mysteriously found that it had shrunk one day. She decided not to give it to her spider friends because she didn't want them to go through what she went through.

Petunia concluded that it had shrunk in the wash.

"We really need to get that washing machine fixed." noted Mary.

When asked how her parents had died, Petunia explained that it was a car crash.

She had been lucky enough to survive, thank goodness, but in the process her head was scarred.

"If only they remembered to put on their seatbelts." noted Mary.

Unfortunately for Vernon and Petunia, when they attempted to call Mrs. Figg to look after their daughter (like she always did whenever the family went on vacation), they discovered that she had broken her leg.

"To think it's Dudley's birthday party too! What are we supposed to do now?" asked Vernon.

"I guess we're going to have to take Mary with us." noted Petunia.

Vernon sighed. It looked they didn't have any other options.

"You can come with us to the zoo, but you better not spoil it for Dudley!" exclaimed the grumpy man.

"You're not taking me to Mrs. Figg's house?" asked Mary.

She liked to look at all the cat photos that Mrs. Figg showed her. Even the black cats.

Though for some reason her house smelled like cabbages. Was she a hardcore vegan?

"If only we could." answered Petunia.

Luckily, Dudley didn't mind. He was bringing his friend Piers with him, but they didn't bully girls.

Piers was afraid of cooties, and Dudley…spent his days being catered by his mother.

"You better not do anything funny." warned Vernon.

Mary decided to put her clown nose and clown wig back in her cupboard.

"By the way, last night I had a dream where I was on a flying motorcycle." noted Mary.

"Motorcycles don't fly. Don't be ridiculous." remarked Petunia.

"Didn't you get Dudley that movie where two of the characters ride a flying bicycle at his last birthday party?" questioned the bespectacled girl.

Vernon groaned.

The five of them went to the zoo, where they all got ice cream. As usual, Mary couldn't help but feel nervous about being in a moving vehicle, but the ice cream made her feel a lot better.

However, Dudley got three while Mary only got one. Dudley chose chocolate while Mary chose vanilla.

"You sure are a big eater, Dudley." noted Mary.

"Didn't you eat that oversized burrito that the lunch lady gave you?" asked Dudley.

"Oh yeah." recalled the girl.

"Don't remind her." warned Vernon.

After having ice cream, the five of them went to the reptile room. Dudley and Piers were hoping that they would find a komodo dragon.

They had seen a boa constrictor, but it didn't seem to do anything.

"This is more boring than I thought it would be." noted Dudley.

"I'm with you there, buddy." nodded Piers.

The two decided to leave.

However, Mary decided to look at the boa constrictor some more.

"Hmm, maybe it's too cold in there. I heard that cold temperatures make reptiles sluggish." noted Mary.

Unlike Dudley, she actually paid attention at school.

"Don't worry, everything is fine." answered the boa constrictor.

"Huh? You can talk?" asked the girl.

"Not to everyone. But you're not just anybody." noted the boa.

"Well, my teachers find me unusual. Though they seem to judge me a bit based on my relationship with my honorary brother." remarked Mary.

He was far from teacher's pet. If he kept up his bad behavior, they just might send a letter to his parents.

Personally, the boa constrictor was flattered that Dudley was fascinated by snakes.

"Can you do me a favor? I wish to go to Brazil." asked the boa constrictor.

"Do you not like it here?" questioned Mary.

"It's not bad, but Brazil is awfully nice this time of year." answered the boa.

"You've got a point there. But I can't break glass barehanded without cutting my hands." noted the girl.

Dudley found that out when he punched through the TV when Mary accidentally changed the channel with the remote. They needed an extra big stretcher for him.

"Don't worry about that. Just press your hands on the glass and I'll do the rest." answered the constrictor.

"Won't they notice you're missing?" asked Mary.

"The zoo is planning to make budget cuts, so I think everything will be alright." explained the boa.

At this point, Potter was convinced.

She nodded and pressed her hands on the glass.

The glass disappeared, and the boa constrictor slithered out.

"Thanks, I owe you one." noted the snake.

He gave her a wink, which surprised her.

"Well, I guess I've done a good deed." remarked Mary.

Suddenly, she heard screaming.

"Huh?" asked the girl.

As it turned out, the boa constrictor had wrapped around Dudley.

He had begged Piers for help, but unfortunately Piers was a coward at heart. Hence him bullying weak kids.

So he decided to hightail it.

"No! Stop!" demanded Mary.

She grabbed the boa constrictor, causing him to let go of her cousin.

"I thought you were going to Brazil." pointed out the girl.

"I am. The only thing is, Brazil is a long trip. So I figured I should eat something before I go. And I figured pork was as good as any." pointed out the constrictor.

"Um, he's not a pig. He's human." explained Mary.

"He did? Well, this is one big misunderstanding. My apologies." noted the boa constrictor.

He uncoiled around Dudley.

"I owe you one…is there any way I can repay you?" asked the boy.

One thing was for sure, he was breaking his friendship with Piers.

"Do you have any bacon?" questioned Mary.

"Well, I was saving it for later, but OK." answered Dudley.

Mary fed the bacon to the constrictor.

"I'll write to you later. Gracias, amigo!" exclaimed the boa constrictor.

Mary waved goodbye.

The boa slithered away.

Dudley scratched his head.

"Mary Lily Potter!" bellowed Vernon.

Mary chuckled nervously.

It seemed she had done something bad.

"You're going straight home…and straight to the cupboard!" bellowed the man.

Oddly enough, Petunia expected Dudley to complain about wanting to stay at the zoo longer. But he didn't.

She sighed in relief.

The four of them went home, and Mary was sent to the cupboard.

She would be there a while.

She had been a baaaaadddddd girl…from her foster parents' perspective, anyway.

When would she be released? Time would only tell.

I certainly hope that none of you end up orphans like Mary Potter.

That would be really sad.

And yes, I would feel sorry for even Dudley.

On that note, I decided not to make him part of the reptile exhibit.
