Well, if Naruto were to wield the Executioner's Blade in a fanfic, it could open up a whole new world of fan art. Imagine the cool drawings of Naruto with this big, menacing blade in his hand. Story - wise, it could also attract new villains who are interested in the blade or are afraid of what Naruto can do with it. This could create a series of intense battles and power struggles within the fanfic's narrative.
The plot might involve Naruto exploring a darker side of his power. Maybe he's pushed to the edge by some great threat and decides to use the 'darkness' within him, which could be some sort of forbidden chakra or a new, shadowy ability. This could lead to him having to face his friends who are initially against his new path but later come to understand his reasons.
In the 'naruto wields suzumebachi fanfic', the plot could revolve around Naruto finding the Suzumebachi during one of his adventures. Since the Suzumebachi is likely a very powerful and unique weapon, Naruto would need to train hard to control it. He may face challenges from other ninja who are envious of his new weapon. Naruto, being Naruto, would use the Suzumebachi not just for fighting but also to protect his friends and the village. He could develop new techniques that are a fusion of his own chakra - based powers and the abilities of the Suzumebachi, making him a one - of - a - kind ninja in the Naruto universe.
Sasuke would likely be one of the main characters to interact with Naruto. Given their complex relationship, Sasuke might be either supportive or skeptical of Naruto's newfound power. Sakura could also be involved, perhaps trying to heal Naruto if the dark power has negative effects on him. Kakashi would surely step in as well, using his wisdom to guide Naruto and make sure he doesn't lose himself in the darkness.
It could be a powerful rogue ninja who wants the Suzumebachi for himself. He sees Naruto as a threat because he has the weapon and decides to target Naruto to get it.
If Naruto wields the dark soul in the fanfic, it could lead to a lot of chaos. His friends might not recognize him anymore. His power would likely increase exponentially, but at the cost of his relationships. He might even be seen as a threat by his own village. The dark soul could also bring out hidden desires and a more ruthless side of Naruto that has been suppressed all this time.
One possible plot could be Naruto discovers the Samaheada in a hidden ancient shrine during one of his solo adventures. He initially struggles to control its power but with the help of Kakashi's guidance and some self - discovery, he gradually masters it and uses it to fend off a new, powerful enemy threatening the Hidden Leaf Village.
Naruto could be initially attracted to Frostmourne's power. He might touch it and start to feel a strange connection, but then quickly realizes the danger it poses.
Another possibility is a new character created specifically for the fanfic. This antagonist could be a dark - chakra user who believes that the Samaheada's power should be used to reshape the ninja world according to his own twisted vision. He would view Naruto as a threat not only because he wields the Samaheada but also because of Naruto's reputation for bringing hope and change to the village.
Perhaps Naruto could be transported to the Warcraft universe where Frostmourne exists. He teams up with the heroes there to stop Arthas, and along the way, he discovers new chakra - like powers related to the Frostmourne's magic.
