Naruto would most likely be one of the main characters. Given the title, there might also be some original vampire characters created specifically for this fanfiction.
Obviously Naruto would be one of the main characters. Since it's a crossover, characters from Bakugan like Dan Kuso would probably be in it too. Maybe Sasuke could also be involved, as he often follows Naruto's adventures in some way. And of course, there would be the Bakugan themselves, like Drago or Pyrus. They would play important roles as partners to the human characters.
Obviously, Naruto would be one of the main characters since it's in the title. He's the one with the 'vampire god' transformation. There might also be his friends like Sasuke and Sakura. Sasuke could be either a rival or an ally in Naruto's new vampire - related adventures. Sakura might be concerned about Naruto's change and try to help him control his new powers.
Well, Naruto is probably the central character as the title implies he has a significant role as the 'first vampire'. Other characters from the Naruto series like Sasuke or Sakura could also be important. They might be involved in Naruto's transformation into a vampire or they could be trying to help him deal with his new state. And of course, there could be some powerful vampire antagonists who play a major role in the story.
I'm not sure about the specific plot of this fanfiction as there could be many different interpretations. It might involve Naruto characters in a world where vampires exist, perhaps with Naruto having some new powers related to vampirism or facing off against vampire enemies.
Naruto and Shinso are the primary ones. But we could also have an old and wise vampire elder as a main character. This elder could have knowledge about a prophecy that involves Naruto and Shinso, and his actions and decisions would drive a lot of the plot as he tries to either fulfill or prevent the prophecy.
The main characters in 'naruto the ultimate lover fanfic' could vary greatly. It might be a self - insert character created by the fanfic author who has an ultimate love for Naruto. Or it could be an original character who has a love story with Kakashi. Since it's a fanfic, the author has the freedom to create new relationships and characters, so it could really be anyone within the Naruto universe who is involved in this ultimate love scenario.
Most likely Naruto would be one of the main characters since it's a Naruto fanfic. He is usually the central figure in any Naruto - related story.
It could be Sasuke. Since the fanfic has 'Sharingan' in the title, Sasuke, who is well - known for his Sharingan abilities in the original Naruto series, might be one of the main characters.
There might also be a mentor figure, someone who has taught the ultimate swordsman their skills. This character could be an old and wise ninja with a lot of experience in swordsmanship.
In some cases, it might focus on the side characters from the original work. The author might have seen potential in these characters to be the main focus in a darker story. So, it could be the less - known characters that get a chance to shine and show their true nature in this 'ultimate darkness' fanfiction.
