Arabelle Narcissa Potter -Draco Malfoy

DISCLAIMERS:
The original books of the Harry Potter series belong to JK Rowling. All the characters as well except for the ones I make up as I go along. I also do not own the Avengers or Tony Stark. They belong to Marvel Industries or whatever. Thanks!
Prologue:
You've all heard of the boy who lived, but what about the girl who disappeared? Arabelle Narcissa Potter is the younger twin sister of Harry James Potter, also known as The Boy Who Lived. That fateful night when Lord Voldemort had come to kill Harry Potter, he was defeated by not only Harry but also Arabelle as well. After the Dark Lord is defeated, Ara disappears as Dumbledore and her godfather, Remus Lupin, and Uncle Sirius Black come back and help their parents. Soon, all the adults rush to the twins' nursery, but "Where's my Belle!" a man with messy auburn hair and glasses cried out.
