Maybe Naruto gets transported to a different dimension or realm where he is somehow forced to become the 'Surgeon of Death'. In this new world, he has to learn a whole new set of medical skills and ethics that are very different from what he knows in the ninja world. He could encounter strange creatures and diseases that only his unique 'Surgeon of Death' abilities can handle. Along the way, he might meet other characters from different universes who either help or hinder his journey to master this new role and use his powers for the greater good.
It could start with Naruto being experimented on by some rogue ninja or a secret organization. As a result of these experiments, he gains the abilities of the 'Surgeon of Death'. At first, he is scared and confused by these powers. But as he starts to understand them, he realizes that he can change the face of the ninja medical world. He might start by secretly helping injured ninja from different villages, which causes a stir among the political powers. Some might see him as a threat, while others see him as a hope for a new era of medical ninjutsu. And all the while, he has to keep his identity as the 'Surgeon of Death' a secret to protect himself and those he loves.
The plot could involve a character with surgical skills in the Naruto universe facing unique challenges. Maybe they use their medical skills not just for healing but also in combat, like using precise cuts to disable opponents' chakra flow. They could also be on a mission to save important ninja from otherwise fatal wounds, adding a lot of drama and action.
It could be an unknown rogue ninja who has developed a unique fighting style based on surgical techniques. He might have been shunned by the ninja community for his unorthodox methods.
Maybe Naruto uses the Forest of Death for special training. He could set up unique challenges for his friends or even for ninja from other villages. It becomes a place where he can test new jutsus without interference.
In a 'Naruto is a surgeon' fanfiction, it might focus on Naruto bringing a new perspective to the medical field. He could use his never - give - up attitude from being a ninja to revolutionize surgical procedures. He might also deal with patients in a very Naruto - like way, inspiring them to fight their illnesses just as he inspired his comrades on the battlefield. His ability to make quick decisions in combat could translate into making life - saving decisions during surgeries.
Maybe it could involve Naruto sacrificing himself to save the village from an ultimate evil. For example, a new and extremely powerful enemy emerges that is immune to all known jutsus except for a forbidden one that Naruto has to use, but it costs him his life.
Perhaps in the fanfiction, the God of Death has been observing Naruto's journey all along. When Naruto is on the verge of losing a crucial battle against an overwhelming foe, the God of Death appears and offers him a pact. If Naruto can endure a set of challenges that test his will, his chakra control, and his understanding of life and death, he will be granted the God of Death's powers to turn the tides of the battle.
One possible plot could be that Naruto somehow gets transported to the Darksiders universe and is mistaken for Death. He then has to adapt to this new, darker world while also dealing with the enemies and challenges that Death would typically face.
Well, it could be about Naruto having some sort of connection to death. Maybe he has powers related to death that he has to learn to control. Or perhaps he's haunted by death in some way, like seeing the spirits of the dead shinobi.
Well, one possibility could be a crossover where Naruto somehow ends up in the world of Death the Kid. Maybe Naruto's chakra is mistaken for some kind of unique soul energy. And Death the Kid, being the perfectionist he is, might be intrigued by Naruto's unruly and yet powerful nature. They could team up to fight some common enemy that threatens both their worlds.
The plot could involve Naruto being a harbinger of death in a way that he has premonitions of upcoming disasters in the ninja world. For example, he might start seeing visions of villages being destroyed and then tries to prevent these tragedies from happening, while also facing skepticism from others who don't believe in his new - found power.
