It could be really interesting. Naruto is known for his strong will and determination. If he had Zangetsu, he would likely try to master it quickly. Since Zangetsu has a mind of its own in the Bleach series, there could be some fun interactions between Naruto and the sword spirit. He might even use Zangetsu to cut through some of the toughest jutsu barriers or opponents that he couldn't defeat with his normal techniques.
Yes, it is possible in fanfiction. In the Naruto universe, Susanoo is typically associated with the Uchiha clan. For Naruto to have Susanoo in fanfiction, one idea could be that through some kind of chakra - related experiment or perhaps a connection with an Uchiha's spirit. It could make for an extremely powerful Naruto. He might use Susanoo's strength combined with his own Sage Mode or Nine - Tails chakra, creating a whole new level of combat abilities.
Perhaps in this fanfiction, Naruto is given White Zangetsu as a gift from a mysterious figure. With it, he discovers new powers and abilities. He might have to train hard to master it, and in the process, he could face challenges not only from his own world but also from forces that are attracted to the power of White Zangetsu. This could lead to new alliances and enemies for Naruto, completely changing the dynamics of the Naruto universe.
One possible storyline could be that Naruto's sister is also a ninja. She might be secretly trained by someone in the village, like an old hermit. And she could be very powerful, having a unique jutsu that even Naruto is amazed by. Maybe she has to hide her identity at first to protect Naruto from some unknown threats in the ninja world.
A possible plotline could be that Naruto's mother returns from the dead in some way. This could create a huge stir in the ninja world. Naruto would have to deal with his new - found family situation while also facing the challenges that come with it. There could be enemies who target his mother because of her connection to Naruto or some secrets she holds. And Naruto would have to learn to balance his relationship with his mother and his duties as a ninja.
One possible plotline could be that Naruto's brother has been living in secret all this time. Maybe he was sent away for his own safety when they were young. He could return to the village and at first Naruto is suspicious, but as they get to know each other, they form a strong bond and fight together against the common enemies of the village.
One possibility is that the son inherits Naruto's strong will and determination. He might struggle to live up to his father's great reputation at first. For example, he could have trouble with his ninja training because everyone expects him to be as good as Naruto right away. But as the story progresses, he discovers his own unique strengths and carves out his own path in the ninja world.
One possible storyline could be that Naruto somehow gains a Hyuuga eye through a unique experiment gone wrong. This new power could initially be difficult for him to control, as the Hyuuga eye has its own set of abilities like the Byakugan. He might struggle to adapt to the sudden change in his vision and the new skills it brings, such as seeing the chakra points clearly. This could lead to some comical moments as he accidentally activates the eye at inappropriate times, but also some intense battles where he slowly learns to master this new power and use it in combination with his existing Rasengan and other techniques.
One possible storyline could be that his older sister was sent away on a secret mission when Naruto was young. Years later, she returns, having gained great power and knowledge. She then helps Naruto in his journey to become Hokage, teaching him advanced jutsu and giving him emotional support during tough times.
Well, one possible tattoo design could be the Uzumaki clan symbol. It would represent Naruto's connection to his family heritage. Since he grew up without his parents, having this tattoo could be a way of carrying their legacy with him. Another could be a tattoo of his Nine - Tails form. It might symbolize his power and how he has tamed the beast within. And a third option could be a tattoo of his friends' symbols combined, like Sasuke's Sharingan and Sakura's forehead protector mark, to show his bond with them.
Maybe Naruto's bat wings are a gift from a mysterious being. This gives him an edge in his ninja missions. He might start exploring caves and other dark places that normal ninjas can't reach easily with his new ability to fly. His friends might be a bit jealous at first but then see how useful it can be for the team as a whole.
