Once Upon a Potter

Disclaimer: I do not own Once Upon a Time or Harry Potter. Edward Kitsis and Adam Horowitz own OUaT, J.K Rowling owns Harry Potter. This is like the story Once Upon a Time: Harry Potter AU, but different.

A/N: This is a Harmony & Captain Swan fanfic.

The new Dark One, Emma Swan, was in a small town. She went to the nearest house and knocked on the door. A teenaged boy with black hair, green eyes like emeralds, and glasses opened the door. "May I help you?" He asked. "Yes you can," She replied. "Where am I?" "You are in Little Whining, Surrey in England." "Thank you, I'm Emma Swan. " She told him. "I'm Harry Potter." She could suddenly see a man beating someone who looked a lot like Harry.

"Harry, may I ask about your childhood?" "Why?" He asked. "Because I saw a fat man beating a child that looked a lot like you." She answered. "Yes, my childhood was like that." He told her. "Do you mind if I step in?" She asked him. "Sure." She went in the house. She went to the fat man and ripped his heart out. "How dare you, you child abuser!" She squeezed his almost pure black heart. He screamed in agony. A lady who looked like a horse screamed "Stop it you freak!". Emma threw her to the kitchen with her magic. The child tried to defend his parents, but Emma put him to sleep. Harry asked "Emma, what are you doing, and how are you doing it? Wandless magic? I didn't know you could rip a heart out." He said with interest. No, I don't know what kind of magic you are used to, but in my world, this is normal magic." Then 2 people popped in with a loud crack, one with pink hair, the other with a normal eye and a large, blue one. "Harry, did you use magic?" The woman asked. "No, Tonks, she did, and it was different than ours." Harry replied. "What do you mean?" The man asked. "She used magic to rip Vernon's heart out and squeezed it and he fell to the floor, she pushed Petunia to the kitchen, and she put Dudley to sleep." Harry told them.

"Where are you from?" Tonks asked. "Storybrooke Maine, United States." She replied. "Oh." The man with the odd eye said. "Yeah." Tonks said. "My name is Mad-Eye Moody." Moody said. "Well, what now?" Emma asked. "We're going to Grimmauld Place," Tonks said. If you want you can come." "I'll take you there." And they disappeared in a puff of black smoke.

A/N: Chapter 1 done. I love OUaT and Harry Potter. That is why I wrote this fanfic. But the next chapter new secrets are revealed at Number 12 Grimmauld Place…
