Disclaimer: Nope Harry Potter and One Piece are not mine.

Summary: Alexis "Lexy" Potter is attacked by a Werewolf before her second year and turned into one. Her magic lashes out sending her to the One Piece world where something affects her inner wolf. Challenge 30 by BlackSeaReaper. Changes explained in prologue.

A girl with shoulder length curly brown hair and vibrant green eyes was walking through the park of her neighborhood in Surrey. This girl was wearing a dark red short-sleeved shirt as well as a pair of dark blue trousers and a pair of sneakers. However if one could see it the most striking feature about her was a lightning bolt shaped scar on her forehead. This girl was Alexis Potter more commonly referred to by her friends as Lexy.

Her reason for being out late at night when no one should conceivably be out this late was that she needed to get a way from her relatives who hated her for having magic. She had just recently completed her first year at Hogwarts and was on summer vacation.

She looked up and smiled as the Full Moon gave her plenty of light. She stopped suddenly as she heard a growling noise behind her. She spun around quickly with her wand out as she saw glowing yellow eyes attached to the form of a werewolf. Fear gripped her as she tried to look for away to escape.

However before she could react the Werewolf howled and lunged at her biting her in the shoulder. She screamed in pain as her magic lashed out blasting the wolf away from her. Her magic then transported her somewhere else.

Alexis panted as she noticed she was in some forest her wand was nowhere to be seen but she didn't expect it to be since she had dropped it. She was surprised that she was still conscious. However before she could think more on it she doubled over in pain and let out a blood-curdling scream as her body began to change.

Her eyes turned from green to yellow with slightly slit pupils. Her body seemed to grow and develop at a rapid pace until she looked more like a 16-year-old beautiful young lady with mid back length hair then a 12-year-old malnourished girl. This rapid growth however had caused her clothes to stretch and tear. Her nails also grew out more and become pointed as well as her canines elongating and turning into fangs. Alexis herself was of course unaware of all these changes for as soon as they had finished she had fallen into unconsciousness.

A red haired man with three diagonal scars over his left eye wearing a white button up shirt and brown pants rolled up above the knees as well as a black cloak walked up and noticed a girl passed out on the ground. He wondered what a girl like this was doing out in the Grandline. Bending down He picked her up with his one remaining arm and lifted her over his shoulder.

Shanks took the girl to his ship and to his cabin ignoring the curious looks he got from his men. After setting her down on the bed he could see her more curious features. These mainly being her claws and the lightning bolt scar.

"Looks like I'll have quite a few questions for you when you wake up." He muttered to himself. He was still surprised at how light the girl had felt.

AN: Okay stopping there next chapter will have a lot more I promise. Also before someone asks yes Lexy is gonna freak out when she learns she is 16 instead of 12.
