Perhaps the fanfiction focuses on the wanderer's search for the true meaning of immortality. Along the way, he could have deep philosophical discussions with Naruto and other characters about life, death, and the purpose of power.
One interesting plotline could be the immortal wanderer's encounters with different villages in the Naruto world. He might share his unique knowledge and skills, which could change the power dynamics in those villages.
There could be other characters like Sasuke as well. Sasuke's quest for power and his complex personality might bring him into contact with the immortal wanderer. Maybe he sees the wanderer as a threat or a source of knowledge, which would make their interactions an important part of the fanfiction.
One interesting concept could be Naruto's 'godlike' powers. Maybe he has abilities far beyond his normal ninja skills, like the power to manipulate time or space. This would completely change the dynamics of the Naruto universe and his interactions with other characters.
Well, it depends on the specific fanfiction. Some might have Naruto going on new adventures in different lands as a wanderer, facing unique challenges and making new friends or enemies along the way.
One possible plotline could be that Naruto discovers a hidden jutsu or artifact that grants him immortality. He then has to deal with the consequences of living forever, like seeing his friends and loved ones age and die while he remains the same. Another could be that an enemy tries to steal his immortality, leading to a great battle.
Perhaps a plotline where Harry discovers other immortal beings. He could form a sort of community with them, learning about different cultures and powers that immortality has bestowed upon them. They might teach him how to better control his immortality, like hiding his true nature from mortals or using his extended lifespan to gain knowledge that no one else has. This could lead to adventures as they try to protect their secret from those who would seek to exploit it.
Perhaps they would face challenges from dark wizards who envy their immortality. They would have to use their combined skills and the wisdom gained over time to defeat these foes. For example, they could encounter a powerful dark wizard who tries to steal their immortality for himself. Percy, with his skills in water magic, and Harry, with his experience in facing Voldemort, would team up in a unique way to combat this threat.
In some Naruto immortal modern fanfictions, the plot focuses on Naruto's role in bridging the gap between the ninja world and the modern world. His immortality gives him a unique perspective as he has seen the ninja world evolve over time. He might work to create a more harmonious co - existence between the two worlds. For example, he could introduce ninja techniques to solve modern problems like environmental issues or security threats, all while dealing with the challenges that come with his immortality.
One interesting plotline could be the mystery behind the mask. Maybe it has some special power that only Naruto can unlock or it could be related to an ancient prophecy. Another could be a new villain who uses the mask to create chaos in the ninja world and Naruto has to stop him.
Perhaps Naruto discovers a new medical jutsu that combines his chakra control with traditional medical knowledge. This could revolutionize the medical field in the Naruto universe. He might use it to heal previously incurable diseases or injuries, and in the process, gain the respect of the medical community. This could also lead to some interesting interactions with other medical ninja, like Shizune or Tsunade.
Well, in some fanfics, there's a plotline where Hinata loses her memory and Naruto has to make her fall in love with him all over again. It's a classic but still very engaging. There are also stories where they are arranged to be married for political reasons at first, but then they actually fall in love for real during the process. And a really unique one is when Hinata becomes a super powerful ninja overnight and Naruto has to deal with his feelings of being a bit overshadowed while also being proud of her.
