Well, it could be portrayed as a jutsu with a mind of its own. For example, in some fanfics, the mist seems to be able to guide the user or even act independently to some extent.
One way is to change its color. Instead of the normal white mist, it could be a purple mist with different properties. In a fanfiction I read, the purple mist had the ability to drain the chakra of those caught in it, which was a really interesting take on the Hidden Mist Jutsu.
In a fanfic, Naruto's teleportation jutsu could be different in terms of its range. Instead of having a set range, it could be based on his current chakra level. So, if he's full of chakra, he can teleport across the entire ninja world, but if he's low on chakra, it's only a short - distance teleport. Also, the jutsu could have a side effect. For instance, every time he teleports, he has a brief moment of disorientation. This would add an interesting element to battles and his overall use of the jutsu. Moreover, the teleportation could be linked to specific landmarks. He can only teleport to places he has a strong mental image of, like his home in Konoha or the training grounds where he practiced with Kakashi.
One great 'Naruto Hidden Mist Jutsu' fanfiction is 'Mist's New Hope'. It focuses on a young shinobi who discovers a new way to use the Hidden Mist Jutsu in a more strategic and powerful way. It has some really cool fight scenes.
The Hidden Mist Jutsu could give Naruto a new strategic advantage. He could use it to cover his movements during battles. Since Naruto is often in the spotlight during fights, this jutsu would let him operate in the shadows for a change. He might be able to develop new combinations with his existing jutsus. For instance, he could use Rasengan while hidden in the mist. This would make it harder for opponents to predict his attacks and defend against them.
In many fanfictions, the Naruto Resurrection Jutsu is often portrayed as a powerful and complex technique. Some fanfictions might show it being used to bring back important characters from the dead to change the course of the story. For example, it could be used to resurrect a fallen comrade right before a crucial battle, tipping the scales in favor of the good guys.
The Bubble Jutsu in fanfiction often takes on new and exciting aspects. It might be used in creative ways during battles. For instance, the user could create a large bubble shield that not only protects but also reflects attacks back at the enemy. Fanfiction writers like to play with the idea of the jutsu's potential, exploring how it could be developed and improved beyond what we see in the original Naruto series.
In some fanfictions, Naruto's barrier jutsu is linked with his emotions. When he's angry, the barrier becomes more aggressive and can even repel attackers with a shockwave. This connection between his feelings and the jutsu makes for a more complex and engaging portrayal of the character and his abilities. Also, the barrier might be able to adapt to different terrains, like being stronger in a forest environment due to Naruto's connection with nature.
In fanfiction, the Naruto Possession Jutsu can be portrayed in various ways. Sometimes it's used for comical effects, like a character accidentally possessing the wrong person. For example, Naruto might end up in Sakura's body and have to deal with all the girly stuff she does, which can lead to really funny situations.
One challenge could be mastering the chakra control required. The Hidden Mist Jutsu demands a precise amount of chakra to create a thick and effective mist. Naruto has had issues with chakra control in the past, so this would be a hurdle. Another challenge might be adapting his fighting style. He's used to more straightforward and aggressive attacks, and the stealthy nature of the Hidden Mist Jutsu would require a different approach.
In terms of relationships, fem Naruto could have a more complex relationship with Sasuke. Maybe she doesn't have the same kind of one - sided crush as Naruto did in the original. Instead, they could start as rivals but slowly develop a mutual respect and understanding that is based on their shared experiences and growth as ninjas.
Nagato, in fanfiction, can be depicted in various ways. Some may show him as a more conflicted character. He has his own beliefs which were shaped by his experiences, like the death of his friends and the destruction he witnessed. He may be more hesitant to change compared to Naruto, but also has the potential for redemption which makes his character interesting.
