I DO NOT OWN HARRY POTTER OR NARUTO; I WISH I DID. THIS IS A NON-PROFIT STORY.
Prologue: Voldemort's Attack, Minato's death
Little Harry and Jack Potter were asleep in their crib on the night of October 31st, 1981 when the Dark Lord Voldemort attacked their house at Godric's Hollow. Lily and James were downstairs asleep on the couch when their door was blasted open, awakening them from slumber. A man with pale skin and red eyes came in followed by a man with rat-like features. James jumped up, "LILY GET THE BOYS AND RUN, I'LL HOLD HIM OFF!" he yelled. Lily ran up the stairs to get her two boys. She got to the crib where the two were still asleep despite the noise; she started to activate the runes around the crib but it was too late. She heard a shout downstairs and then a thump like a body hitting the floor and slow footsteps coming up the stairs. She scurried around faster in her attempt to save her sons; Voldemort came in the door to the nursery brandishing his wand. "Step aside woman and I'll spare your life."
"NO, NO, PLEASE NOT MY BABIES!" She stood in front of the two, as if guarding them. "CRUCIO MAXIMUS" Voldemort yelled and she landed on the ground, in a deep coma. "There, that should be good enough for Severus" He walked over to the toddlers who were now awake and looked at them in disgust. "One of you will defeat me? What a ridiculous notion; neither one of you are more than babies soiling their night wrappings. That prophecy is ridiculous." One of the boys stood up and spread his arms as if to block whatever Voldemort cast at him. 'This is the one, if either of them is, this will be the one that is a danger to me in the future' he thought and pointed his wand at the boy's small face, "No offense kid, but I can't chance you actually defeating me" and he cast the spell at the boy. He watched as if in slow motion, the bolt of green light hit the child's body and saw the light go out of the child's eyes as he collapsed. Then the light rebounded at him, as if the boy's sacrifice had caused it, and hit him; he was blown backwards and blasted through the roof, and Voldemort fell for the first time and Harry Potter died that night.
OoOoOoOoOoOoOoOoOoOoOoOo
Across a veil long forgotten by the people of the wizarding world, except the goblins, a nine-tailed fox attacked a large village by the name of Konohagakure and a blonde man fought it's ever destructive claws. Minato Namikaze, the Yondaime of the shinobi world, sealed the beast inside his beloved son and fought what remained of the beast's power. His wife, Kushina, came to help but was weak and unable to do much. As a last act, Minato and Kushina jumped in front of the beast's mighty claw and got stabbed through, protecting their son Naruto. The claw stopped just inches from the child's frail body as Minato and Kushina took the blow. The child lived on, always wondering who his father was, in the village of Konohagakure. Minato and Kushina died that night, praised as heros.
The Shinigami that was still watching the proceedings felt pity for the child and realized that across the forgotten veil was another death in defense of another, another child lost. He could not bring back the dead, but he could transfer the soul. The child across the veil was already dead but this blonde-haired man was not, not yet. He took Minato's soul and transferred it to the child's body, that lie vacant across the veil. The blond-haired man would relive life in a different body, but he would have all his memories, experiences and abilities. As soon as the man's new body reached the age of three, he would regain all of his powers as well; he would be as strong and as fast as he was when the demon-fox destroyed him the first time, by the age of three. The Shinigami would prep the child's body to be able to handle the man's abilities then and he would slowly gain the looks of himself when he was younger. When the boy turned three, he would look as if he was a child version of the man in front of him. So Minato Namikaze was reborn at the death of Harry Potter. The world was in for a surprise. The Shinigami couldn't wait.

Minato woke up in a strange place made of, dare he say it, light. "What's going on here?"
A raspy voice from behind him spoke, "Hello, Minato" He quickly turned to see a Shinigami floating behind him. He gasped in shock. The Shinigami spoke again, "I assume that you know that you died, so I'll skip that part and just continue from there. The shinobi world is hidden by a veil, I'm sure you know as well having been Hokage. I'll assume that you know what witches and wizards are as well. In the outside world, there is a Dark wizard known as Voldemort. He went to a small family's house to get rid of a child of prophecy. He stunned the child's father and put the mother into a coma when they tried to protect their children. Once the parents were out of the picture, he went to the children, twins, and one stood up to protect his brother from Voldemort and was killed; he was one year old. Voldemort's body, however, was destroyed by the backlash from the child's sacrifice and his soul floats around the world unhindered. I cannot bring back the dead, but since I removed your soul from your body before you died, you do not count. I plan to put your soul into the child's body to take his place, because Voldemort is not dead and needs to be before he kills more. If you accept, I will tell you all you need to know."
Minato thought a moment, "Yeah, I guess so."
The Shinigami grinned, "Excellent. The boy's name is Harry Potter and his twin's name is Jack. The mother and father are Lily and James. You will have all of your memories and skills. When you turn three, your body will transform into that of yourself when you were younger, but you will have all of the skills, abilities, and powers that you had when the demon-fox destroyed your other body. As a plus side, your soul is just getting transferred, so when you go back it will be the same time that you died. The shinobi world will go on regularly. By the time you're eleven Naruto will be eleven and I will tell you how to get to the shinobi world once again. Your vault at Gringotts will also be accessible by blood once you turn three as well. When you turn eleven, you will be required to go to the wizarding school, Hogwarts. Watch out for the old man, Dumbledore; he is a manipulative, senile, old fool."
"Are you done yet, Shinigami?" Minato asked the specter.
"Why you cheeky little brat, yes I'm done; prepare to wake up in a one and a half year old body, Minato."
