I'm not entirely sure if there is a specific 'Naruto can lava bend' fanfiction. Fanfiction covers a vast range of concepts and ideas. While lava bending is more associated with the Avatar universe, in the world of Naruto fanfiction, someone could have come up with a story where Naruto somehow acquires this ability. It could be due to a new jutsu he discovers, or maybe a strange encounter with some sort of elemental spirit. But without thoroughly searching fanfiction websites, it's hard to say for certain.
You can start by looking at popular fanfiction websites like Fanfiction.net or Archive of Our Own (AO3). Just use their search functions and type in relevant keywords like 'Naruto' and 'lava bend'. However, keep in mind that there might not be a large number of such stories, so you may need to sift through some results to find exactly what you're looking for.
In this fanfiction, Naruto might be able to bend not only the basic elements but also some rarer ones. He could bend lightning, which is extremely powerful and fast. He may also have the ability to bend light, allowing him to create illusions or blind his enemies. Another element could be shadow. By bending shadow, he can use it for stealth, trapping opponents in shadows, or even traveling through them. There could also be a special 'spirit' element that he can manipulate, which is related to the energy of living things.
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.
In fanfiction, the writer could create a scenario where Naruto is exposed to some sort of magical or otherworldly energy that gives him the ability to fire bend. For example, he could stumble upon an ancient artifact that transfers the power of fire bending to him.
In many fanfictions, Naruto might discover his element - bending ability through a dangerous encounter. For example, he could be in a fight against a powerful enemy where his normal jutsu are ineffective. This desperate situation forces him to tap into some latent power within himself, and he unknowingly starts to bend the elements. It could also be due to some kind of ancient prophecy or training from a hermit - like figure that reveals his hidden potential.
Another fanfiction could involve a situation where Azula is transported to the Naruto universe. She might mistake the lava - based attacks in the Naruto world as some advanced form of firebending. Naruto and his friends would be both curious and cautious about this powerful newcomer with her unique abilities related to fire and Naruto's lava - like jutsu could play a role in their interactions.
Lava release in Naruto fanfiction can be a unique element to explore different plotlines. Some fanfictions might focus on a character developing lava release abilities from scratch. This could involve intense training sequences where the character has to endure extreme heat and learn to control the volatile nature of lava. It also opens up the possibility of new jutsu combinations, like mixing lava release with other elements such as wind to create a more devastating attack.
I'm sorry I can't recommend a specific one right now. But like I said before, searching on FanFiction.net or Archive of Our Own using 'Naruto lava style' should give you some good results.
In a Naruto lightning bender fanfiction, the story could focus on how this lightning - based ability affects the character's combat style. For example, they could be extremely fast and agile like lightning itself. They might also develop unique jutsu that combine their lightning - bending with other ninja techniques, creating a whole new set of powerful attacks.
