He might start acting more like Tobirama. Tobirama was a very serious and methodical person. So Naruto could become more calculated in his actions. Maybe he would be more cautious in battle and rely less on his usual impulsive nature.
The story could involve Naruto going on a journey to understand Tobirama better. He could visit places that were important to Tobirama and learn about his past. Along the way, he might face enemies who have a vendetta against Tobirama's legacy and he has to defend it while dressed like him. This would not only test his physical skills but also his knowledge of Tobirama's ways.
In this kind of fanfiction scenario, Naruto might become an even more powerful ninja at a faster pace. Tobirama was a highly skilled shinobi with a lot of unique jutsu knowledge. He could teach Naruto some of his advanced water - style jutsu, which would add a new dimension to Naruto's combat abilities. Also, Tobirama was good at strategic thinking, so Naruto could learn more about battle tactics from him.
Well, Naruto has his own unique style, so dressing like Tobirama would make him look more solemn. Tobirama's style is more traditional and reserved. Naruto might look less of his boisterous self with Tobirama - like robes and maybe a different hair - style to match. His bright orange jumpsuit would be replaced by something more in line with Tobirama's era, like dark - colored robes perhaps. It would be a big change from his usual look.
Well, he might get some really strange looks from his friends at first. They might not recognize him right away. Then they could start teasing him about it.
It would be really different from the original Naruto story. For one, Naruto might have different abilities or a different upbringing. Maybe he would be trained in Tobirama's unique jutsu from a young age. And his place in the village hierarchy could be much different as well, perhaps being seen as a sort of royalty due to his connection to Tobirama.
There could be a backstory where Madara and Tobirama had a secret agreement that led to Naruto's existence. Maybe they foresaw a future threat and planned for Naruto to be born with their combined power to save the ninja world. Naruto would then have to uncover this mystery and fulfill his destiny.
If such a fanfiction existed, it would probably be a very complex story. It would need to deal with how Naruto, a male character, could become pregnant, which might involve some kind of unique ninja magic or jutsu. Also, the relationship between Naruto and Tobirama would have to be carefully developed. Since they are from different generations, their values and goals would be different. And the story would also need to consider the reactions of the other characters in the Naruto universe, like Sasuke, Sakura, and the rest of the village.
In fanfiction, if Tobirama was Minato's father, there would be many implications. Minato's character could be developed with a stronger connection to the Senju clan. His values might be more in line with Tobirama's, such as a greater emphasis on village unity. In terms of abilities, as mentioned before, he could inherit more of Tobirama's water - based jutsu and perhaps his space - time ninjutsu would be even more advanced due to Tobirama's knowledge in similar areas. The story could also explore how Minato's relationships with his peers, like Kushina, would be different. Maybe Kushina would see Minato in a new light, considering his prestigious family background. And Minato's role as a teacher to the next generation, like to Naruto, could also be influenced by Tobirama's teachings that he passed down.
In a 'naruto and tobirama fanfiction' fight, it depends on the circumstances. If Tobirama was able to set up his water jutsu traps and strategies beforehand, he might be able to hold his own against Naruto. But overall, Naruto has shown the ability to overcome seemingly impossible odds and opponents much stronger than Tobirama. He has a wider range of abilities, from his Rasengan variations to his ability to sense and counter attacks. Tobirama would put up a good fight, but Naruto's power and experience from facing some of the toughest foes in the ninja world would probably give him the upper hand.
One possibility is that Tobirama would be impressed by Naruto's determination. Naruto's never - give - up attitude might remind Tobirama of the strong - willed shinobi in his own time. He could see Naruto as a symbol of the new generation that has carried on the spirit of the Hidden Leaf. Tobirama might even offer Naruto some unique insights into the history of the village and the development of jutsu, which could help Naruto become even stronger.
In a fanfiction where Naruto is trained by Tobirama, Naruto might quickly become a master of water jutsu. Tobirama was a genius in water techniques, and he could pass on his in - depth knowledge to Naruto. Naruto would also likely learn more about the founding of Konoha and the Uchiha - Senju relations from Tobirama directly, which could give him a different perspective on the village's politics and history.
