Bardock is the central figure in this fanfic. However, the story could potentially introduce other important Saiyan leaders or elders that he might interact with regarding his new - found knowledge of the future. And if the future he sees involves battles and conflicts, then the foes that the Saiyans will face, whether they are alien races or powerful villains, could also be considered as important characters in the context of the story as they shape Bardock's view of the future.
Obviously, Bardock is one of the main characters since it's about him watching the future. There could also be other Saiyans like Gine, his mate. And depending on how the story goes, perhaps some of the more well - known Saiyans from later in the Dragon Ball timeline could make an appearance, like Vegeta or Goku, even if just in Bardock's visions of the future.
Well, it could be about Bardock having some sort of vision or ability to peek into the future. Maybe he sees the fate of his race, the Saiyans, or perhaps the coming of powerful foes. It might also involve his personal journey in light of what he discovers about the future.
Since I haven't read it, I can't say for sure. But likely, the members of Class 78 are the main characters. They could be students with different personalities, skills, and backstories that play important roles in how they interact with the vision of the future.
Obviously Naruto is one of the main characters since it's about him watching the future. Sasuke would also likely be a key character, given their long - standing relationship. And Kakashi, as Naruto's former teacher, could play an important role too.
I don't know for sure without reading it. But if it's about the 78th class, it might include the typical characters associated with that class in the original work. Maybe the leaders or the more prominent students within that class could be the main characters.
There could be an inventor as a main character, who created the 78b watches and is trying to protect them from being misused in the future.
He could meet his descendants like Goku or Vegeta. It would be an interesting encounter as they have different upbringings and personalities compared to Bardock.
In addition to RWBY, other important characters like Qrow or Ozpin could also be focused on. Qrow has a lot of history and his own future could be intertwined with RWBY's. Ozpin, with his vast knowledge and secrets, might also play a crucial role in how they view the future. His wisdom could be used to help them understand what they see, or he might also be a part of the future they witness in unexpected ways.
Often, Goku is paired with Bardock. Since they are father - son, it makes for an interesting dynamic in the fanfic. Bardock can see how his son has grown and influenced the universe, and Goku can learn about his Saiyan heritage directly from his father. Another character could be Vegeta. They can bond over their Saiyan pride and work together to protect the Saiyan race or take on common enemies.
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.
Well, aside from Naruto, Sasuke, and Sakura, Kakashi Hatake could also play an important role in this fanfiction. He is their teacher, and he might guide them through their experiences of seeing the future. He could help them understand what they see and how to use that knowledge to their advantage in the present.
