Well, it could be that Naruto, under Minato's training, quickly masters powerful jutsus. He might learn advanced space - time ninjutsu faster than in the original story. With Minato's guidance, Naruto could also develop unique combat strategies, making him seem godlike in battles against tough opponents like the Akatsuki members.
In this fanfiction scenario, Naruto's training with Minato and Kushina would be intense. Minato, being a prodigy, would push Naruto to his limits in terms of combat skills and quick decision - making. Kushina would focus on Naruto's inner strength and the connection to his Uzumaki roots. This could result in Naruto having a more well - rounded set of skills from the start. He might not struggle as much with basic jutsu control and could potentially even master some advanced Uzumaki - specific techniques earlier. For example, he could have a better grasp on sealing techniques which are a big part of the Uzumaki clan's abilities. This would give him an edge in battles against opponents like Orochimaru or the Akatsuki members who often use or are affected by sealing jutsu.
The Akatsuki could still be the main antagonists. Even with Naruto being trained by Minato and becoming godlike, the Akatsuki's goals of collecting the tailed beasts would put them in direct conflict with Naruto. Their powerful members, like Pain or Itachi, would pose a great challenge to Naruto, despite his new skills.
Naruto's personality would be a blend of his own natural exuberance and the more composed natures of Minato and Kushina. He might be less impulsive as Minato's strategic thinking would influence him. Also, Kushina's strong - willed nature would make him more determined and less likely to be swayed by others' negative opinions.
Their relationship would become closer. Naruto would finally have the father - son bond he always desired. Minato would be able to pass on his wisdom and skills directly to Naruto, which would make Naruto feel more connected to his family.
One interesting plot development could be Naruto quickly mastering a new jutsu that Minato was famous for, like the Flying Thunder God Technique. This would give Naruto an edge in battles and also create a connection between him and his father on a more practical level.
One common ability is their speed. Minato was known as the Yellow Flash for his incredible speed. Naruto, with his Sage Mode and later forms, can also move extremely fast. Another is their use of the Rasengan. Minato created the Rasengan, and Naruto has mastered it and even developed it further.
One possible reason could be for Naruto's protection. Maybe Minato knew of some great danger that was coming for Naruto and he thought that banishing him would keep him out of harm's way. Another reason might be related to some prophecy or hidden power within Naruto that Minato feared could be misused if Naruto stayed in the village.
One popular theme is Minato getting to know Naruto in the afterlife. Since Minato died when Naruto was a baby, fanfictions often explore their relationship in a spiritual realm.
In the 'naruto is more like minato fanfiction', their relationship with the Nine - Tailed Fox could be similar. Minato sealed the Nine - Tails within Naruto. So, in fanfiction, Naruto might show a deeper connection to the Nine - Tails that is reminiscent of Minato's understanding and handling of the powerful beast. Maybe Naruto has an easier time controlling the Nine - Tails' power because he is more like Minato, as per the fanfiction. This could also tie into their overall power levels, as both being strong shinobi with a special relationship to the Nine - Tails.
