Naruto: Shadowwatch

In this story, things happened differently for Naruto. The fourth shinobi war happened not long after the fight with Pain. During that war, everyone Naruto loved and cared for died. After the huge tragedy with nothing left in the world, Naruto gathered up everything salvageable from his world before using a dimensional transport jutsu to teleport to a new world. After using the jutsu Naruto ends up in a world filled with superpowers, magic, heroes, villains, and aliens. When Naruto lost everything and everyone he had nothing left and no goal in life as his dreams to be Hokage and earn the village's respect as well as their acknowledgment was not possible. When he came to the new world he had no plan, no goal, and no purpose but after saving a group of people in a fire and receiving thanks for his work Naruto found a new purpose to use his skills and knowledge to protect his new home with everything he has. When Naruto first arrived in his new world he stayed mostly isolated and refused to get close to anyone while still being willing to help people in Tokyo when they needed it. However, things don't go as planned because, in the end, Naruto becomes a part of a new team, gets a new friend, meets people some people he will see as family, and gains a harem of girls who are stubborn enough to break through his walls winning his heart.
