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.
Another common character could be the Mentor. In many fanfictions, Lightning has a mentor figure who guides him in his journey, whether it's an old and wise wizard or a retired hero. There might also be a love interest. Let's say a character named Aurora who has a special connection with Lightning, and their relationship development can be a big part of the story.
I'm not sure exactly as I haven't read this specific fanfiction. But it's likely to feature some of the main RWBY characters like Ruby, Weiss, Blake, and Yang. Maybe there are also some original characters created by the fanfiction author.
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.
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.
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.
Definitely Percy Jackson from 'The Lightning Thief' and Iron Man from the Avengers would be main characters. Iron Man with his high - tech gadgets and Percy with his demigod powers would make for an interesting duo. They could play off each other's strengths and weaknesses. Maybe Iron Man is constantly trying to analyze Percy's powers with his technology while Percy is just like 'Let's just go and fight already!'
It's hard to say for sure without reading it, but it's likely that Harry Potter himself would be one of the main characters, as it's in the title. Hermione and Ron could also be involved since they are Harry's closest friends in the original series.
Obviously, Harry Potter would be one of the main characters. He would be the one most likely to interact with the concept of the 'Lord of Lightning'.
Well, Peter Parker is definitely one of the main characters. He's the one with the spider - powers and now, in this fanfiction, has something to do with thunder and lightning. There could also be his friends like Ned Leeds. Ned might be the one who helps Peter understand and control his new powers related to thunder and lightning. Maybe MJ (Michelle Jones) is also there, providing moral support and being part of Peter's life as he deals with these new abilities.
Obviously, the Lightning Lord is a main character. There could also be the classic Harry Potter characters like Dumbledore who might play a role in the story. They could be either guiding the Lightning Lord or trying to figure out their intentions.
