His relationship with Sasuke might become more complex. Sasuke, who has always been somewhat cold - natured, could be either drawn to Naruto's fiery energy or feel threatened by it. Sakura might be more cautious around him at first, afraid of getting burned. But as she realizes Naruto's good heart beneath the fire, she could become more protective of him.
One idea could be that since Naruto is made of fire, he has an uncontrollable heat that causes problems in his daily life in Konoha. For example, he accidentally sets things on fire when he gets excited. Another plot could involve him using his fire - based body to develop unique jutsu that are different from the normal ninjutsu. Maybe he can create a shield of fire to protect himself and his friends in a new way.
Yes, in certain fanfictions Naruto is immune to fire. This can add an interesting twist to the story. For example, if he's facing a powerful fire - using enemy, his immunity gives him an advantage. It also allows for new plot developments and character interactions that wouldn't be possible in the original story.
Well, in fanfiction, just about anything can happen. Since it's not bound by the strict canon of either the Naruto universe or the Avatar universe (where fire bending comes from). Writers can give Naruto the power to fire bend. They might do this to create new plotlines, like Naruto using fire bending to fight a new kind of enemy or to master a new form of combat. It's all about creativity in the world of fanfiction.
Well, in the realm of fanfiction, anything is possible. There could be fanfictions where Naruto is made of chakra. This could be a way for the author to explore different aspects of the Naruto universe. Maybe it's a way to show a more spiritual or elemental side of Naruto. It could also lead to new plotlines like how he copes with being such an unusual being in a world where most people have chakra but aren't made of it.
There's also the 'Inferno Storm Jutsu' in some fanfictions. It creates a large - scale storm made entirely of fire. The fire in this storm has different intensities, with the center being the hottest and most destructive. It can cover a large area, making it a great offensive move against groups of enemies.
There are fanfictions where Naruto uses the black fire after making a pact with a powerful entity. This entity could have granted him the ability to use the black fire. He may use it in a strategic way during battles, like surrounding his opponents with walls of black fire to trap them.
One idea could be a story where a new character discovers they have a unique fire - based ability that is different from the typical fire jutsu in Naruto. They could struggle to control it at first, causing chaos in their village, but then learn to harness it with the help of an old master.
Perhaps in a fanfiction, a fire - using ninja and an ice - using ninja are forced to team up. They initially dislike each other due to their elemental differences. But as they face common enemies, they gradually learn to respect and rely on each other's skills.
Well, it could be about Naruto having some sort of special connection to the god of fire. Maybe he gains new powers related to fire that are god - like. For example, he could have the ability to control fire in ways that no one else can, like creating huge firestorms or even fire creatures.
