Disclaimer: I do not own either Naruto of Harry Potter. Things would be different if I did.

This idea (or at least parts of ideas) has been on my mind for quite some time now. After not being able to fall asleep at 2 in the morning and left without internet (don't ask) to get on LoL or try out FPS games again I decided to write some of these ramblings down. This was literally done in an hour so if there are any mistakes feel free to let me know.

"Avada Kedavra."

"NO!" screamed Lily as she threw herself forward.

Her body slumped lifelessly to the ground as the green light hit her. A faint smile was left on her face, unnoticed by the man that was focused on the child in front of him.

Harry Potter was laying in his crib, all signs of crying stopped, as he stared at Voldemort with innocent curiosity as the green orbs that were his eyes followed his every movement. He knew what was going on, in a sense. The realization of the futility of crying dried his tears and instead he observed.

Voldemort raised his hand slowly and said with finality, "Avada Kedavra."

As the green light hit Harry, Lily's blood wards came into effect, activated by her death and tripped by that spell. It bounced back and struck Voldemort in the chest when something interesting happened.

The Killing Curse worked by removing the target's "soul" from its body, effectively rendering the body a lifeless sack of flesh. Lily Potter had known in advance that she could not find a ward that would protect her son from every type of attack in the future and eventually there would be something that got through, so she improvised. Taking a ward that was originally meant to reflect spells, she used what little knowledge of blood wards she had and turned it into a shield that would reflect malicious spells back at the user. Since Avada Kedavra was a dark spell, it could be countered by a dark shield which was what she had turned the blood ward into.

There were some disadvantages to it, however. It would only be active for an hour's time once activated and would reflect any malicious spells within the radius of the ward. James Potter had agreed that the both of them would not be able to fight off Voldemort while still protecting Harry and things could go wrong if any of the variables changed within the ward which meant that he had agreed to forgo any chance of living to insure that their son would instead. This gave Lily enough time to set up the ward and die in the right circumstances for things to be in place for what happened next.

Instead of destroying Voldemort's soul which would have given him more chances to finish the job owing to his horcruxes, it literally ripped the magic from his body. However, as mentioned before, some of the variables were not the same as specified in the blood ward. There had to be two "souls" for it to work properly but Voldemort only had 3.125% of a soul residing within his current body as he had made 5 horcruxes. Instead of simply destroying the magic from Voldemort, it was thrust into Harry Potter without precision or carefulness, throwing his core into haywire as it compensated for the core of a 70-year-old core of one of the most powerful wizards in the world to meld with.

Voldemort let out a small, strangled cry and fell to the floor, dead. Lily's mistakes and lack of knowledge had actually worked in her favor as, instead of getting rid of Voldemort's soul, it attacked what he had no defense for.

When the hour that the ward was active for ended, it should have simply dissipated, but because of Lily's inexperience with blood wards, things didn't go as planned. Harry's soul was thrown into a sea of different dimensions, flashing in and out of each one with only a glimpse to show for each one, much like traveling with floo.

As this was going on, Harry's instinctive yearn for safety and protection drew his soul to a random dimension and sought out the most powerful force there.

As Harry's soul left, so did the magic from Voldemort. Without his magic in the universe to support his horcruxes, they quietly died, fulfilling the prophecy and releasing Harry from his connection to that universe.

When Dumbledore later found the bodies, he lamented the deaths of his favorite students and their child. He resolved to spend the rest of his life making sure that Neville Longbottom (as he was the only other child that even remotely fit the criteria set by the prophecy) would be ready for the day that Voldemort returned.

Voldemort never did end up returning and Neville had simple received free training from one who was widely regarded as the most powerful wizard since Merlin.

It made finding a job depressingly easy.

In the previously mentioned random dimension, the sealing of the Kyuubi into Naruto was happening and as the giant force of nature was sealed, a small flash of light lit up the area where the baby Naruto was at and everything calmed. Naruto had disappeared.

The body had appeared some distance away from the area in which the battle had taken place and was lying on the ground silently somewhere in the village.

Inside of the mindscape of Naruto was a different matter. Harry's soul was still in turmoil as everything that had happened to it so far was pushing it to the point of where it was about to break. The sewer-like mindscape that held the Kyuubi's prison chaotically forming and reforming itself into different scenes as two souls instinctively fought for dominance.

The only sign of the struggle going on inside of Naruto's body was the tensing of his limbs as they locked up and released randomly.

A civilian looked out some time later as sounds of the fighting had stopped and saw a child on the ground in the middle of the streets. Checking around to make sure that there was no danger, he quickly ran outside and picked up the twitching child.

When he brought him inside he wrapped him up in a blanket and made sure that he had no obvious injuries.

As the night came to a close he set the still moving body down on the couch. He made sure that the baby wouldn't randomly roll off onto the floor by surrounding it with more cloth and decided to find out whose child it was the next day.

Some time during the middle of the night, Naruto's body relaxed and stilled.

His eyes opened. The left was a brilliant green and the right was a shining blue.

So what do you guys think? I feel like there's a lot that I can do with this setup and it'll probably be really fun to write.

Questions and comments are welcome!
