Well, it really depends on the specific fanfic. However, it could feature some new versions of the classic Naruto characters. Maybe a more mature Naruto with different leadership qualities. Or perhaps a Sakura who has developed a completely new fighting style.
It might also introduce entirely new characters as the main protagonists. They could be from a different region of Naruto Universe 6. For example, a young ninja from a far - off village who has a unique power related to the spiritual energy of that area. This character could then interact with the more familiar Naruto - like characters and change the dynamics of the story.
Sometimes, in Naruto Universe 6 fanfic, the main characters could be descendants of the original characters. So we might see a son or daughter of Sasuke with a whole new set of challenges and abilities. Their story could be about living up to their parent's legacy while also forging their own path in this new and different Naruto universe.
Since it's a fan - made concept, the main characters could be some of the less - known characters from the Naruto universe who get a chance to shine in this broken - universe scenario. For example, Rock Lee could be a key figure, using his unique taijutsu skills to navigate the chaos. Or perhaps some of the older generation like Kakashi could be guiding the younger ones through the mess.
In this 'naruto alternate universe naruko fanfic', apart from Naruko, Kakashi could be a significant character. He might be Naruko's mentor, guiding her through her ninja training. And Hinata could be another main character. Maybe she has a special connection with Naruko, like they are on a joint mission to protect the village from a new threat. Additionally, there could be new characters created specifically for this alternate universe who interact closely with Naruko.
Bardock is probably the central figure in the 'bardock universe 13 fanfic'. However, depending on the plot, there could be other important characters. Maybe there's a powerful villain in this universe 13 who constantly challenges Bardock. Or perhaps there are some friendly characters, like a wise old hermit who gives Bardock advice on how to deal with the unique challenges of this universe. His family members, if they exist in this universe, could also play significant roles.
Perhaps there are characters with different skills like a navigator, a scientist, and a survival expert. They each contribute in their own way to the journey in the fanfic.
Naruto himself is often reimagined. Writers like to explore different versions of him, such as a Naruto with a darker personality. Sasuke is also popular. In some AUs, he could be a more carefree character. And Kakashi is another one. Maybe a Kakashi who didn't have to endure so much trauma at a young age.
Obviously, Naruto is the main character. He is the one who becomes this 'god - like' figure in the fanfic. But there are also other important characters like Sasuke. Sasuke might play a role in either supporting Naruto's new power or being in conflict with him because of it.
Obviously, Lars would be one of the main characters. But without reading it, it's hard to say who else. It could be characters related to Ash, or other original characters created specifically for this fanfic in Ash's universe.
The main characters are likely Steven and Lemons Fresh. Steven is a well - known character from the 'Steven Universe' series, being half - human and half - gem. Lemons Fresh is also an important character in this fanfic, though might be a less known or original creation specific to the fanfic.
Obviously, Spider - Man is one of the main characters. He's the one who gets the Captain Universe powers. And Mary Jane Watson might also be a main character as she's an important part of Spider - Man's life. Another could be J. Jonah Jameson, who always has an interesting take on Spider - Man's activities, especially when he becomes this more powerful version.
Well, it's likely that Steven would still be one of the main characters. He often plays a central role in any Steven Universe - related story. Alongside him, there could be new characters created specifically for this fanfic that are somehow connected to the Black Diamond. And of course, any of the existing main Gems from the show like Garnet, Amethyst, and Pearl might also be important characters in this fanfic, especially if they interact with the Black Diamond in some way.
