So! I bring you a new story even though I haven't updated The Truth About Alchemy and Magic. I had to write this one because it was the most amazing idea I had! I realized there aren't many big Harry Potter and Once Upon A Time crossovers so I decided to write this. This will be slash but I haven't decided on the pairing yet, Regina will not end up with Robin Hood but instead she will end up with a wizard from the Wizarding World. Henry will still exist it's just it's two years prior to Harry being born as when he goes to find Emma Henry's like 10 years old and the curse had existed for 28 years so yeah Harry's going to be Henry's big brother. Hope you enjoy! Read and Review!

Disclaimer: I do not own Harry Potter nor do I own Once Upon a Time, I do however own the current plot! As it is something that popped in my head

Harry Cora Mills

It was a dark night in Godric's Hollow on the thirty-first of October the year 1981, also known as All-Hallows' Eve, Samhain, or Halloween. Kids were running around in costume going from door to door getting all the candy that they wanted. Not a thing was out of sight except for one thing. There was a tall, bald, snakelike man walking up to a quaint little cottage. He was wearing a black robe and in his hand was a thin stick. He walked up to the door, swung the stick, and pointed it at the door. Suddenly the door exploded forward and you could hear people behind the smoke.

"Lils! Take Harry and go!" A male voice yelled, followed by the sound of feet going up stairs. The snake man swung his stick again and yelled

"Avada Kedavra!" A dark green light flew from the stick and hit the man, who fell to the ground dead. The man then elegantly walked to the staircase and headed up to where the woman ran. There was a red headed woman sitting in front of a crib and in the cradle was a black haired baby.

"Please not Harry! Take me instead!" She plead out in a desperate voice. The snake man sneered at the woman and pointed his wand at her.

"Move aside little girl." He snarled out "No! Take me not Harry!" The man glared at her and pointed the stick at her and shouted "Avada Kedavra!" The same green light flew out and hit the woman, making her drop dead.

"This little baby is supposed to be my doom? Pathetic! Avada Kedavra!" The light flew to the baby but something happened. The room suddenly exploded, the snake man screaming before his body was torn apart into ashes. The baby now had a lightning bolt shaped scar on his forehead and was crying.

Hours later the baby was in a motorcycle with a giant of a man that was flying over England.

"Don't worry young Harry you'll be safe now." The giant said. A few minutes later they landed in front of two people. One was a middle aged woman with graying but black hair wearing black robes and glasses. The other one was an old man with a long white beard and colorful robes who was wearing half-moon spectacles. This was Minerva McGonagall and Albus Percival Wulfric Brian Dumbledore.

"Hagrid," said Dumbledore, sounding relieved. "At last. And where did you get that motorcycle?"

"Borrowed it, Professor Dumbledore, sit," said the giant, climbing carefully off the motorcycle as he spoke. "Young Sirius Black lent it to me. I've got him, sir."

"No problems, were there?"

"No, sir - house was almost destroyed, but I got him out all right before the Muggles started swarmin' around. He fell asleep as we was flyin' over Bristol."

Dumbledore and Professor McGonagall bent forward over the bundle of blankets. Inside, just visible, was a baby boy, fast asleep. Under a tuft of jet-black hair over his forehead they could see a curiously shaped cut, like a bolt of lightning.

"Is that where -?" whispered Professor McGonagall.

"Yes," said Dumbledore. "He'll have that scar forever."

"Couldn't you do something about it, Dumbledore?"

"Even if I could, I wouldn't. Scars can come in handy. I have one myself above my left knee that is a perfect map of the London Underground. Well - give him here, Hagrid - we'd better get this over with."

Dumbledore took Harry in his arms and turned toward the Dursleys' house.

"Could I - could I say good-bye to him, sir?" asked Hagrid. He bent his great, shaggy head over Harry and gave him what must have been a very scratchy, whiskery kiss. Then, suddenly, Hagrid let out a howl like a wounded dog.

"Shhh!" hissed Professor McGonagall, "you'll wake the Muggles!"

"S-s-sorry," sobbed Hagrid, taking out a large, spotted handkerchief and burying his face in it. "But I c-c-can't stand it - Lily an' James dead - an' poor little Harry off ter live with Muggles -"

"Yes, yes, it's all very sad, but get a grip on yourself, Hagrid, or we'll be found," Professor McGonagall whispered, patting Hagrid gingerly on the arm as Dumbledore stepped over the low garden wall and walked to the front door. He laid Harry gently on the doorstep, took a letter out of his cloak, tucked it inside Harry's blankets, and then came back to the other two. For a full minute the three of them stood and looked at the little bundle; Hagrid's shoulders shook, Professor McGonagall blinked furiously, and the twinkling light that usually shone from Dumbledore's eyes seemed to have gone out.

"Well," said Dumbledore finally, "that's that. We've no business staying here. We may as well go and join the celebrations."

"Yeah," said Hagrid in a very muffled voice, "I'll be takin' Sirius his bike back. G'night, Professor McGonagall - Professor Dumbledore, sir."

Wiping his streaming eyes on his jacket sleeve, Hagrid swung himself onto the motorcycle and kicked the engine into life; with a roar it rose into the air and off into the night.

"I shall see you soon, I expect, Professor McGonagall," said Dumbledore, nodding to her. Professor McGonagall blew her nose in reply.

"Goodbye young Harry" Dumbledore said, before walking off and disappearing with a crack that resounded throughout the night.

Young Harry didn't know that he was special or that he was famous for defeating the most powerful Dark Lord of the time. He however did know instinctively that if he did stay here his life would be absolutely horrible. So his magic decided to act out and did something to save him. Suddenly he disappeared with a crack that was similar to Dumbledore's which left nothing behind whatsoever.

It was a nice afternoon morning in Storybrook, Maine, everyone was walking around doing their stuff. However a certain resident was getting a shock of her life. Regina Mills was the Mayor of Storybrook and ran the town. She was considered a cruel woman but that was more often than not far from the truth. She lived in a nice white townhouse that had a lovely apple tree. She however held a secret from everyone else. She was the Evil Queen from the Snow White story. She had cast a curse upon the Enchanted Forest, the place that which all the fairy tale characters lived in. This curse took everybody to this world and wiped their memories but hers. She had cast this curse because she had wanted to be able to win for once in her life, ever since Snow White as a kid cost her the man that she was in love with. She had been getting bored with this life because it was extremely repetitive and nothing new ever happened. That was until today. She was lazing around her house because of the boredom that she was experiencing until she heard a resounding crack. She ran to the front door and opened it. She gasped at what was on her doorstep. It was a little baby bundled in blankets with black hair and a lightning bolt scar. In his hands was a letter, which she immediately picked up. It was addressed to a Mr. and Mrs. Dursley, though that didn't matter to her as she immediately opened it and read it:

Dear Petunia and Vernon Dursley,

It pains me to tell you that your sister Lily Potter nee Evans has been killed Petunia. She and her husband was murdered by a wizard who titled himself as a Dark Lord and named himself Lord Voldemort. Here in front of you is your nephew Harry James Potter. In the confrontation Lord Voldemort cast an unforgivable curse called the Killing Curse at Harry. Fortunately Lily's love for Harry seemed to reflect the curse and eradicate Lord Voldemort. I implore you to take care of your nephew as if he was your own. Around his 11th birthday an owl will come with letter entailing his invitation to Hogwarts School of Witchcraft and Wizardry please let him know about his magic beforehand. Also to forewarn you, he may cast accidental magic in moments of extreme emotion. Also if possible when you take him to get his supplies and to get the money ask for an inheritance exam.

Sincerely

Albus Percival Wulfric Brian Dumbledore

Order of Merlin (First Class), Headmaster of Hogwarts School of Witchcraft and Wizardry, Supreme Mugwump of the International Confederation of Wizards, and Chief Warlock of the Wizengamot

Regina didn't believe anything that the letter was spouting off as she believed that when she cast the curse it had taken her and the other fairy tale characters off to a world without magic. However she was soon corrected when she took a look at Harry. He was reaching for his blanket, why you might ask? It was because the blanket was floating above him! This caused Regina to gasp out loud.

'There's magic here?! But I could have sworn Rumple said that this world would have no magic! If there is magic then why can't I use mine?' she thought in utter shock.

However what happened next caused her world to break. Harry looked at Regina and reached his hands out to her.

"Mommy!" He shouted as he reached his hands out to her.

For some reason this word cause Regina to break down into tears and anyone who knew her would be shocked at this action. Crying, Regina knelt down and pulled Harry into her arms and kissed his forehead.

"Yes, I'm your mommy." She whispered to him.

She grabbed the blanket and basket in her other hand and took everything inside. She set the basket on the table and sat Harry down in the basket.

"What am I going to do? I need to get a room set up for him and everything. I know this goes against everything I believe in but I'm going to have to call Snow and ask her to watch Harry so I can go buy everything for him." She said pacing back and forth before finally walking over to the phone.

She then dialed Mary Margaret and waited for her to pick up

"Yes, Mary Margaret speaking." Said the voice on the other end of the phone.

"Yes, Mary Margaret I need you to watch my son so I can get his room set up." Regina replied.

"Ms. Mayor? Since when do you have a son, wait never mind I'll be right over." Mary Margaret replied.

About ten minutes later there was a knock at the door and Regina answered it, and at the door was a young woman with short black hair and green eyes.

"Good you're here Mary Margaret, he's sitting on the table in there, I shouldn't be gone too long I just have to get a crib, baby formula, diapers, and a stroller really." She said as she grabbed her coat and put it on.

Mary Margaret nodded and watched as Regina wrote down a number and handed it to her.

"Here's my number just in case something goes wrong. Thanks again" Regina said, although that thanks was a bit strained.

It wasn't until about an hour later that Regina returned and she had men coming in with her who were carrying all sorts of supplies. Mary Margaret looked around the corner from the kitchen with Harry in her arms and stared in shock.

"I thought you were grabbing just a few things." She said in total surprise.

"I was but then I decided to spoil Harry a bit so I bought a bit more, though they aren't painting the room I am." She said with an air of determination.

"Well if you want I can put Harry to sleep and help you with the room?" She asked kindly.

Normally Regina would outright say no as this was her worst enemy but looking at the way Harry was smiling at Mary Margaret she immediately changed because a thought that came to her.

'Harry I won't have you grow up with a cold heart like I did, I will change for you Harry and nobody else.' She thought with a smile forming on her face.

"Sure, just let me go grab a few aprons so we won't make a complete mess." She said as she headed off.

Mary Margaret placed Harry in the basket and rocked him until he fell asleep and she took him upstairs and set him outside what would be his new room. Inside the room was Regina with four different colors of paint; green, silver, red, and gold. She had also set down the tarp and everything and was wearing an apron. She saw Mary Margaret looking in the doorway before she beckoned her in.

"Come on what are you waiting for!" She said smiling.

Mary Margaret came in and they proceeded to start painting, occasionally taking care of Harry. Regina accidentally got paint on Mary Margaret which proceeded her to get paint on Regina before they were fighting with paint. When they saw the mess they created they broke out laughing.

"My gosh that's the most fun I've had in forever." Regina said with a clear smile on her face.

Mary Margaret nodded, smiling back at her. It didn't take long after that to finish painting the room. When they finished Regina had to gasp at the work Mary Margaret had did. See Regina had focused on the base and Mary Margaret asked if she could pain pictures for Harry and Regina didn't see any harm. However this wasn't what she was expecting. Mary Margaret had painted magnificent pictures of Snakes and Griffins on the walls and amazing designs.

"Why didn't you tell anyone that you're this good of an artist?" She asked in shock.

"You think I'm good? This isn't much really, I doodle these for the kids I teach." She said with a blush on her face.

Regina nodded and turned her head towards Harry and an 'aww' slipped from her mouth when she saw Harry cuddled up to his blanket. Mary Margaret looked where Regina was looking and awed too. They snapped out of it and then proceeded to finish the room by setting everything up. Regina had decided to have Harry sleep with her tonight because the paint wouldn't be dry till the next day. She saw Mary Margaret out and in a quick decision asked her to come over tomorrow for some tea which Mary Margaret agreed to. Regina was whistling as she went upstairs with Harry in her arms. It was late at night and time for both of them to go to bed so she went to her room with Harry and tucked him in with her. She smiled at him and began to sing to him, a lullaby that her mother when she had actually cared for her sang to her.

Somewhere over the rainbow way up high

There's a land that I heard of once in a lullaby

Somewhere over the rainbow skies are blue

And the dreams that you dare to dream really do come true

Someday I'll wish upon a star

And wake up where the clouds are far

Behind me

Where troubles melt like lemon drops

Away above the chimney tops

That's where you'll find me

Somewhere over the rainbow bluebirds fly

Birds fly over the rainbow. Why then, oh, why can't I?

If happy little bluebirds fly

Beyond the rainbow why, oh, why can't I?

Soon Harry was fast asleep which again made her smile. She kissed his forehead and curled up next to him.

"Goodnight my little Harry. From now on you will be Harry Cora Mills." She said as she slowly nodded off to sleep.

This signified a huge change in the Evil Queen's life, for she was slowly becoming Good. As the years progressed she would find that Harry had completely changed her life for the better and for that she was grateful.

Thanks for reading! Read and review please! I would immensely enjoy it!
