If Minato and Mei were his parents in the fanfiction, Naruto could inherit Minato's strategic thinking. Minato was a master strategist, and this could be passed on to Naruto. From Mei, he could get her passion. Mei was passionate about her village and her beliefs. Naruto would also likely inherit Minato's loyalty. Minato was loyal to the Hidden Leaf, and with Mei's influence, Naruto's loyalty could extend to a broader concept, perhaps including his new family ties and different villages. This would make his character more multi - faceted in the fanfiction world.
Naruto could inherit Minato's calm and intelligent nature. Minato was known for his quick thinking in battle. From Mei, he might get her boldness. Mei was never afraid to speak her mind and take risks. So Naruto could be a combination of being smart in combat situations like Minato and fearless like Mei.
Naruto could pass on his determination. He's always been someone who doesn't give up easily, and Minato might inherit that. Also, his loyalty. Naruto is extremely loyal to his friends and the village, and Minato could grow up with those values. Maybe even Naruto's love for ramen would be passed on in some comical way.
If Minato and Mei were Naruto's parents in a fanfiction, the story would take a whole new turn. In the original, Naruto was an outcast because of the Nine - Tailed Fox sealed within him. But with Mei as his mother, there could be different reactions from the village. Also, Naruto's training would be different. He might learn from Mei's combat style which is more aggressive and fluid compared to what he learned in the original. And the mystery surrounding his parents would be completely different. Instead of just the legacy of Minato, there would be the added mystery of Mei's influence and her village's secrets that could be passed on to Naruto.
One power Elena could inherit is Naruto's willpower. Naruto's unwavering will has been crucial in his many battles. Elena could have this same strong will, which would make her a formidable force against her enemies. In terms of more physical powers, she could potentially inherit the ability to use Rasengan. Although it might be in a different form in her world, it could still be a very powerful attack. Also, Naruto's ability to connect with others on a deep level could be passed down, allowing Elena to form stronger bonds with her friends and allies, which could be a power in its own right when it comes to facing challenges together.
She could inherit Naruto's chakra. This would give her an extra source of energy that she could use in combat. Maybe she could use it to enhance her physical strength like Naruto does when he taps into his chakra. Also, she might inherit his ability to perform the Rasengan. She could combine it with her sword - fighting skills for a really unique and powerful attack.
He might inherit Naruto's shadow clone jutsu. This would be really useful for Markov. He could use the clones to gather information, fight multiple enemies at once, or even learn new skills faster by having the clones practice simultaneously. Also, Naruto's enhanced physical strength and speed, which come from his chakra, could be passed on to Markov, making him a formidable fighter in the fanfiction.
Since Yoruichi has strong spiritual energy in her world, Naruto might inherit some form of enhanced chakra that has spiritual aspects to it. This could give him new jutsu or abilities that are a blend of his original ninja skills and this new spiritual - chakra power. For example, he could use his new power to sense things in a different way, like Yoruichi can sense spiritual presences.
Naruto could inherit Tsunade's medical ninjutsu skills. This would be a huge addition to his arsenal. He could use it to heal his comrades more effectively during missions. Also, he might inherit her ability to store chakra in his forehead. This would give him an extra boost of power when he needed it most. And perhaps he could also learn some of Tsunade's more precise combat techniques that rely on her strength and accuracy.
In this fanfiction, Naruto might inherit Grimmjow's ability to adapt quickly in combat situations. Grimmjow was known for his improvisation during battles, and Naruto could have that same skill. Also, Grimmjow's sense of loyalty, though in a different way than Naruto's original loyalty, could be passed on. While Naruto was loyal to his friends and village, he might have a more primal and individualistic loyalty similar to Grimmjow's loyalty to his own kind or those he respects.
The baby might inherit Sasuke's brooding and determined nature. It could be very focused on achieving its goals, just like Sasuke was on his revenge mission. At the same time, from Sakura, it could get a sense of compassion. So it might be a complex character who is tough - minded but also caring towards others.
He could be the son of a rogue ninja who abandoned him in Konoha for some unknown reason. This would add an element of mystery to his past.
