Perhaps in a fanfic, a time - traveling villain kidnaps Naruto's parents alive. Naruto, with the help of his friends like Sakura and Kakashi, uses a special jutsu to travel back in time as well. They then have to fight the villain in the past while also ensuring that Naruto's parents are safe and can be brought back to the present.
Naruto would likely become more determined. His usual goal of becoming Hokage might be put on hold as he focuses on rescuing his parents. He would train harder, pushing his limits to gain the strength needed to face the kidnappers. This would accelerate his growth as a ninja.
One possible scenario in such a fanfiction could be that Naruto's parents are preoccupied with their shinobi duties. They might be constantly on missions for the Hidden Leaf Village, leaving Naruto at home with caretakers who don't really pay him much attention. This could lead to Naruto feeling lonely and isolated, just as he did in the original story when he thought he had no family.
One great fanfic could be 'The New Beginning for Dark Naruto'. In this, Naruto's parents being alive changes his whole outlook. Instead of the lonely and somewhat bitter Naruto we know, he grows up with the love and support of his parents. His father, Minato, trains him personally, and Kushina is always there to give him emotional support. This alters the course of his journey in a positive way, making him less likely to turn to the 'dark' side as he has a strong family unit.
One possibility in a fanfiction where Jiraiya is alive could be that he returns during the Fourth Great Ninja War. He could use his vast knowledge and powerful jutsu to turn the tide of the war. Maybe he teams up with Naruto again and helps him master new forms of the Rasengan or other powerful techniques.
The story would be very different. Naruto's parents being alive would mean he has a support system from the start. His father could pass on his jutsu and wisdom more directly. Naruto might not have the same drive to become Hokage in the same way, as he wouldn't be seeking that family - like recognition from the village. His mother's presence would also add an element of warmth and stability to his life. And perhaps he would be more of a prodigy with both his parents' guidance, changing the power dynamics in the ninja world.
I really liked 'Back to the Beginning with Naruto'. Here, when Naruto travels back in time, his parents are alive. The story focuses on how Naruto tries to prevent the tragedies that happened in the original timeline. It's interesting to see how his knowledge from the future impacts the past. For example, he is able to warn his father about certain threats, and it changes the course of events. And the relationship between Naruto and his parents is beautifully portrayed, full of love and understanding.
One interesting 'Beth kidnapped' fanfiction could be one where she's kidnapped by a mysterious group and her friends have to embark on a quest to rescue her. They might face various challenges along the way.
One great fanfiction with Harry's parents alive is 'The Potter Family Returns'. It's a heartwarming story that shows how different Harry's life would be. His parents get to guide him through his Hogwarts years, and there are some really cute family moments, like family dinners in the Gryffindor common room. It also has some interesting new plotlines with the Marauders being involved in Harry's adventures.
One possible plotline could be that Naruto is banished due to false accusations of endangering the village, despite his parents being alive. His parents, Minato and Kushina, might be powerless to stop the decision because of some political intrigue within the village. Naruto then has to find his own way in the outside world, facing new enemies and making unexpected allies.
One possible fanfiction could involve Marco being kidnapped by an enemy from a rival group. His friends then embark on a dangerous mission to rescue him. They might face various challenges and puzzles along the way, like in a mystery - adventure type of story.
