Well, one way this could work is through some sort of multiverse concept. Maybe in a parallel universe, the Force and chakra are related in a way that Anakin Skywalker's essence or some part of his power gets transferred to the Naruto universe and he somehow becomes Naruto's father. It's a really wild idea but in fanfiction, anything is possible.
In this fanfiction scenario, the training Naruto would receive could be a blend of Jedi training and ninja training. He might learn to use a lightsaber - like weapon along with his kunai and shuriken. His sense of justice could be even more intense, influenced by both the values of the ninja world and the Jedi code. And his relationships with his friends, like Sasuke, could be seen in a new light, perhaps Sasuke representing a sort of Vader - like figure that Naruto has to bring back to the 'light side' of their world.
There could be a great conflict between the ninja clans and those who see Naruto's new powers as a threat. Meanwhile, Naruto would be on a journey to understand his father's legacy. He might try to find out more about Anakin Skywalker's story and how he ended up being related to him. Along the way, he would have to deal with his own internal struggles, similar to Anakin's, between the power he has and the responsibility to use it for good.
A fanfiction could also be about Shmi's dreams and hopes for Anakin. It could show her thoughts as she watched him grow, knowing he was special. For example, she might have had visions of his future in the Jedi Order and the great things he could do, but also feared for him because of the dark side she sensed was a threat.
In fanfiction, Anakin's character can be expanded through alternate timelines. Let's say a fanfic has him not turning to the dark side. We can then see how his character would have developed as a powerful Jedi without the influence of the Sith. It also allows for exploring his relationships with other characters like the clones in ways that the movies didn't fully cover. Writers can create scenarios where Anakin has to lead the clones in different battles and how that shapes his leadership skills and his view of the war.
In such a fanfiction, perhaps they could engage in a lightsaber duel to test each other's skills. The female Skywalker might be from an alternate timeline or a previously unknown part of the Skywalker family. They could also exchange stories about their experiences with the Force.
In fanfiction, when Luke meets Anakin, they might have an intense emotional reunion. Luke could finally get the father - son relationship he always desired. Anakin might impart some long - lost Jedi wisdom to Luke,弥补 the time they lost when Anakin was Darth Vader.
Anakin could be part of a time - travel story in a fanfiction. What if a character from Star Wars Rebels was sent back in time and met Anakin before his fall? They could try to change the course of his future, which would have a huge impact on the events of Star Wars Rebels and the entire galaxy.
It could be about Harry learning about Anakin's story and being inspired by his journey from a young slave to a powerful Jedi. Maybe Harry sees similarities in their struggles against dark forces. He could try to apply some of Anakin's teachings or experiences to his own battles against Voldemort.
In fanfiction, Ahsoka Tano and Anakin Skywalker often have a complex relationship. They could be seen as a master - apprentice duo with a deep bond of loyalty. Anakin might be portrayed as a protective mentor to Ahsoka, guiding her in the ways of the Force.
A powerful crime syndicate could be responsible. They see Anakin as a valuable asset. Maybe they think they can sell him to the highest bidder, whether it's the Sith or some other powerful entity in the galaxy. They would use their extensive network of informants and thugs to carry out the kidnapping.
Often, it would be depicted as a very emotional moment. Luke might be filled with a mix of awe, anger (for Anakin's past as Vader), and longing for a true father - son bond. Anakin could be shown as a figure full of remorse, reaching out to Luke in a desperate attempt to make amends.
