The main character is Naruto for sure. When it comes to the Anbu, there could be some new and original Anbu characters created just for this fanfiction. They could have unique abilities and personalities. Naruto's relationship with these made - up Anbu characters could be really interesting. He might prank them in ways that play off of their individual quirks. For example, if one Anbu is really proud of his speed, Naruto could set up a prank that makes it seem like he's much slower than he thinks.
Obviously, Naruto would be one of the main characters as he is the one being saved. And then there would be members of the ANBU. They could be some well - known ANBU members from the original Naruto series or some original characters created specifically for this fanfiction.
Obviously Naruto is the main character as he is the one usually pulling the pranks. His friends like Shikamaru might also be involved, either as victims of the pranks or as accomplices. Sakura could be in there too, perhaps getting annoyed at Naruto's pranks or being part of a prank on someone else.
Obviously Naruto himself is the central character as it's about his hibernation. His friends like Sasuke and Sakura are also likely to be involved. They would probably be the ones most concerned about his condition and try to figure out what happened.
Obviously, Percy Jackson himself. He's the one doing the pranking. Then, there would probably be the gods like Zeus, Poseidon, and Athena who are the targets of his pranks. His friends like Annabeth might also be involved, either helping Percy with the pranks or trying to stop him when they think he's going too far.
Naruto is the primary one for sure. But there could be other characters like Jiraiya. Jiraiya is known for his knowledge of various things in the Naruto universe, and he could play a role in teaching Naruto about demon breeding. Additionally, some of the demon characters themselves could be considered main characters in a sense. They would have their own personalities and goals, and their interactions with Naruto would be a major part of the story. For example, a powerful demon that Naruto is trying to breed might have a complex backstory and motives that drive the plot.
In this fanfiction, Naruto is the key figure. However, characters like Shikamaru, who is known for his intelligence, might also be involved. He could be helping to plan Naruto's welcome or dealing with any potential issues that Naruto's return might bring. Also, Hinata, given her relationship with Naruto, would surely be part of the story. And the elders of the village may also play a role, as they often have a say in important matters regarding the village and its shinobi.
In a 'naruto chronal accelerator fanfiction', Naruto is almost certain to be involved as he is the heart of the Naruto story. However, other characters like Sakura could also play a major role. She might use the chronal accelerator to go back and improve her skills at an earlier time. Additionally, Orochimaru might be interested in the chronal accelerator for his own devious purposes, like trying to gain more power by changing the past or finding new ways to experiment with his immortality.
Sasuke would also likely be involved. Given their long - standing relationship and rivalry in the original series, Sasuke would surely have an opinion on Naruto's connection to the Chaos God. He might either try to help Naruto control this new power or try to take it for himself, depending on how the story is written.
Obviously, Naruto would be one of the main characters. He's the one being betrayed. From RWBY, Ruby, Weiss, Blake, and Yang are likely to be involved. They are the central characters in RWBY, and if there's a betrayal of an outsider like Naruto, they would probably play a significant role in it.
Naruto would probably be a central character. Given that he is the protagonist of the original series, in a fanfiction about the power of darkness, his reaction to this new and dangerous power would be crucial. Sasuke is also likely to be involved. His own struggle with power and his complex relationship with Naruto could be further explored in the context of the power of darkness. Kakashi, as a mentor figure, might play a role in guiding or trying to prevent the younger characters from being consumed by the power of darkness.
