This is my first crossover so flames and advice are welcome.

I'm a WHAT?

Lilly Potter was looking at her new child. She was cute but she looked exactly like her biological father, not like her or James. Oh god how was she supposed to tell him? She was sure he would understand though; maybe even pretend like he was her dad.

That night she took the baby home to her husband and son. Harry was happy to have someone to play with and James was being very understanding.

They heard a knock at the door. James got up to answer it and he didn't come back. "Honey, what's taking so long?" asked Lilly. When she got no answer she got up to look. She found her husband dead on the floor. She ran back to her children, hurried them into Harry's room, and shut and locked the doors and windows, knowing it would be of little use against the dark lord. She heard him moving down the hall, trying every room. He finally came to Harry's door. He opened it with a swish of his wand.

"No! No! Not my children, anything but my children!" she pleaded.

"Avada Kedava," in a calm, almost bored, voice, as if he did this every day. He turned on the two children. "Avada Kedava," he repeated. But somehow, the spell backfired. Lord Voldemort screamed and dragged himself out of the house.

The two children were crying for their mommy, they both had a new lightning shaped scar on their heads. A massive man came through the door and carried the two out to his flying motorcycle.

The next morning, when Petunia Dursley went out to get the milk, she came upon the two children and uttered a startled shriek. She saw the note and discussed what to do with the two. They decided to keep them.
