One advantage is that he can use lightning - based jutsus more efficiently. For instance, he can perform them with less chakra consumption. Also, it can give him an edge in battles against opponents who are weak against lightning attacks.
In some fanfictions, Naruto's high lightning affinity might show up as him being able to quickly learn lightning - based jutsus. For example, he could master advanced lightning techniques like the Chidori in a very short time, much faster than in the original story. He might also be able to combine his existing skills with lightning chakra more effectively, creating unique and powerful attacks.
One common theme is the struggle to control the lightning affinity. Since lightning is a powerful and somewhat wild element, characters often have to learn to tame it. Another theme is the discovery of new lightning - based jutsu. Writers like to explore how characters can innovate with their lightning chakra. And there's also the theme of rivalry, especially against those with other elemental affinities.
One great 'naruto lightning affinity fanfiction' is 'Lightning's Ascent'. It follows a young ninja with a strong lightning affinity as he trains under Kakashi. Another one is 'The Lightning's Path' which focuses on a character who discovers a unique way to enhance their lightning - based jutsu. And there's also 'Lightning in the Shadows' that has an interesting plot about a ninja using lightning jutsu for stealth and assassination missions.
If Naruto has an insane lightning affinity in fanfiction, it could transform his combat style. He might be able to create large - scale lightning storms as attacks. His lightning could also be used for defensive purposes, like creating a shield of lightning. This would make him a more versatile fighter, as he could switch between offensive and defensive lightning - based moves with ease.
Maybe a 'Lightning Cloak' jutsu. This would surround him with intense lightning energy, increasing his speed, strength, and also acting as a defense. He could also create a 'Lightning Prison' jutsu, where he traps his enemies in a cage made of lightning.
Well, Naruto's strong lightning affinity in fanfiction could lead to him creating unique lightning - infused attacks. He might develop a new jutsu where he combines his Rasengan with lightning, creating a powerful and electrifying version of it. This new jutsu could be used to cut through tough defenses that are resistant to normal attacks. Also, his lightning affinity could make him more resistant to lightning - based attacks from his enemies, almost like he has a natural shield when facing such attacks.
One fanfiction that comes to mind is 'Naruto: Earth's Champion'. In this story, Naruto discovers his high earth affinity early on and is trained by an old sage who specializes in earth - style jutsu. He goes on to use his earth powers to defend his village from a new, powerful enemy that is immune to most other types of attacks.
A lesser - known but really good one is 'Naruto and the Suiton Ascent'. This fanfiction focuses on Naruto's struggles and triumphs as he tries to perfect his Suiton techniques. It's a more character - driven story, exploring his relationships with his peers and how his newfound affinity affects them as well.
A popular fanfiction in this regard is 'Lightning - Blessed Naruto'. Here, Naruto's lightning affinity is not just about combat. It also has a spiritual aspect. The story follows Naruto as he tries to understand the deeper meaning of his connection to lightning, and how it relates to his destiny as a shinobi. He meets ancient spirits that are related to lightning and they guide him on his journey.
