Who are the main characters in 'the heir and the spare twilight fanfiction'?

I'm not sure specifically as there could be many different interpretations in this fanfiction. It might be about the concepts of 'the heir' and 'the spare' within the Twilight universe, perhaps exploring different characters' roles as heir or spare in the vampire or werewolf hierarchies.

Well, obviously the black heir is one of the main characters. Their actions and decisions drive a lot of the story.

The main characters are likely to be the ones from the original 'Twilight' like Bella, Edward, and Jacob. In fanfiction, they might be portrayed in different lights or with different personalities.

There could also be some well - known Naruto characters who play important roles in the story. For instance, Naruto or Sasuke could be involved, either as mentors or as characters who are somehow related to the events involving the heir. Maybe Naruto helps the heir come to terms with the deaths they are associated with, or Sasuke has some knowledge about the secrets behind the deaths that the heir needs to know.

Well, obviously Harry would be the main character. Since he's the heir of the founders in this fanfiction.

Obviously, Harry is one of the main characters. There might also be his friends like Ron and Hermione. Since it's about being a founders heir, perhaps there will be appearances from the ghosts of the founders or characters who are descendants of the founders' friends or foes.

Hermione and Ron are likely to be main characters too. They are Harry's closest friends in the original series, and in this fanfiction, they would probably play important roles in helping Harry understand and deal with his new identity as Merlin's heir. They might assist him in researching about Merlin, or they could be by his side when he faces new challenges because of this heritage.

Obviously, the heir of Madara would be a main character. There might also be other characters from the original Naruto series, like Naruto himself. Naruto could be in opposition to the heir, seeing them as a threat to the peace he has worked so hard to achieve.

Obviously, Harry Potter is one of the main characters since the story is centered around him being the heir of Black. Sirius Black might also be an important character, as he was a Black himself and could play a role in Harry's discovery or training. And of course, Harry's friends like Hermione and Ron would likely be involved too.

Obviously Naruto would be one of the main characters. There might also be his usual friends like Sasuke and Sakura. But since it's a fanfiction about him being the heir of chaos, there could be new characters introduced who are related to this chaos aspect, like some ancient beings or a secret clan.
