In some fanfictions, it could be an enemy-turned - ally. This character, who originally fought against Naruto, realizes his strength and potential and decides to teach him black lightning as a way to make amends or to join forces with him for a greater cause.
Well, in many fanfictions, Naruto might learn black lightning through intense training. Maybe he gets some special guidance from a powerful shinobi who has mastered it, like Kakashi or some other unknown but strong character. He could also discover some ancient scrolls that contain the secrets of black lightning.
Compared to other bloodlines, the black lightning bloodline in the fanfiction could be rarer. In the Naruto universe, some bloodlines are more common among certain clans. But the black lightning bloodline might be something that only a very few individuals possess. This rarity could make characters with this bloodline targets or special heroes. Also, its powers might be more adaptable. For instance, while some bloodlines are mainly for defense or sensory abilities, the black lightning could be used in a variety of combat and non - combat situations.
Sasuke is another popular choice. Given his thirst for power and his natural aptitude for lightning - based techniques, fanfiction writers often explore how he would obtain and master the Black Lightning. It could be a part of his journey to become even stronger and seek revenge against his enemies.
The black lightning Naruto uses in fanfiction can offer several advantages. Firstly, it can act as a great deterrent. Just the sight of him summoning the black lightning can make his enemies think twice before attacking. Secondly, it could be used in combination with his other skills. For example, he could infuse his shadow clones with black lightning, making them more dangerous. This would not only increase his combat capabilities but also add a new layer of strategy to his battles.
In some fanfictions, Naruto might learn to use black lightning through special training with a powerful ninja who has mastered it. Maybe he discovers a new chakra nature within himself that allows him to manifest the black lightning.
Well, in DxD fanfiction, the Naruto Black Lightning could be incorporated in various ways. For example, it could be a power that a character from the Naruto universe who somehow ends up in the DxD world brings with them. This power might be used to surprise the devils, angels, and fallen angels in the DxD world as it's a completely different type of energy compared to what they are used to. It could also potentially be combined with the magic or sacred gear abilities in DxD to create unique combat techniques.
In some fanfics, Naruto might learn to use Black Lightning through special training with a master who has knowledge of this unique ability. Maybe he discovers an ancient scroll or meets a hidden shinobi who teaches him the secrets behind it.
Naruto himself is likely to be one of the main characters. Since it's a Naruto fanfiction, he would probably play a central role. Maybe he'll be the one who discovers the power of Black Lightning and tries to incorporate it into his own fighting style. Another likely character could be Sasuke. He's always been Naruto's rival, and if Naruto starts using new powers, Sasuke would surely be interested in it too.
In 'Black Lightning Naruto Fanfiction', a great idea could be the exploration of new jutsu inspired by Black Lightning. The fanfiction might introduce a new type of lightning - based jutsu that is more powerful and has different properties than the normal lightning jutsu in Naruto. Also, it could be about the training methods. What if Naruto or other ninjas had to train under the principles of Black Lightning? That would be really cool.
