Obviously Naruto is one of the main characters since it's in the title. And Lightning Farron is likely to be a main character too, as Naruto is supposed to be his son in this fanfiction. There may also be other Naruto - universe characters like Kakashi or Jiraiya who could play important roles in the story.
In the 'Naruto Son of Lightning Farron' fanfiction, Naruto is a main character as the title implies. Lightning Farron, who Naruto is the son of in this story, is another key figure. Other Naruto - related characters may also be important. For instance, Hinata might be involved, especially if the story explores Naruto's relationships in the context of his new family background. And villains from the Naruto world could also be present, like Orochimaru or Pain, who could pose threats related to Naruto's new identity and the secrets it may hold.
I'm not sure specifically as there could be many different interpretations in this fanfiction. It might be about Naruto having some connection to a character named Lightning Farron, perhaps in an alternate universe where Naruto's origin or abilities are related to this new element of 'Lightning Farron'.
There could also be an old and wise wizard named Merlin. Merlin has vast knowledge and magical powers that he uses to guide Dark Lightning Farron on his adventures. He can also be a source of comic relief at times with his eccentric ways.
One of the appealing aspects of including Lightning Farron in RWBY fanfiction is the potential for crossovers. Writers can explore how the technology and magic of her world interact with the Grimm - filled world of RWBY. It also allows for character development for both Lightning and the RWBY characters as they face new challenges together.
Often, the main character could be an original character created by the fanfiction writer who has a special connection to the crimson lightning. Maybe they are a young ninja trying to prove themselves in the Naruto world.
One common theme is identity. Since she's in a crossover situation, Lightning often has to re - evaluate who she is in the new context. For example, in crossovers with other fantasy worlds, she might question her role as a warrior.
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.
Sasuke could also be a main character. His pursuit of power and his natural affinity for lightning - based techniques might lead him to be involved with the Lightning God power. He could either be a rival for it or a partner in harnessing its strength.
Well, of course, Lightning is the main character in most Lightning fanfiction. But often, there are also side characters like his friends or comrades. For example, in some fanfictions, there could be a character named Flash who is Lightning's best friend and they go on adventures together.
Naruto himself is often associated with it. Since he is the main character of the series, many fanfictions explore his potential with the Lightning Armor. He might learn to use it in unique ways, like combining it with his Rasengan.
Often, Naruto himself is a main character. Since he's the protagonist of the original series, it's common to see him involved with the lightning sword in fanfiction. Sasuke could also be a main character as he is always in search of power and the lightning sword could be something that attracts him. Another character might be Kakashi, who could guide the younger ninja in their journey with the sword.
