Obviously, Naruto would be one of the key characters. He's the main protagonist and his opinions often matter a great deal in the village. Also, Shikamaru, with his high intelligence, might be present and play an important role in the discussions.
The Hokage, whether it's Tsunade or Kakashi in different parts of the Naruto timeline, would be a central figure. They lead the village and would be in charge of the council meeting. Additionally, the elders of the village like Danzo (if the story is set before his actions are fully exposed) could also be key characters, as they often have strong opinions and influence over the council's decisions. There could also be some of the clan leaders, like the Nara or Akimichi clan leaders, who would represent the interests of their clans during the meeting.
The council members themselves would be key characters. They are the ones making the decision to banish Naruto. Also, characters like Iruka sensei could play an important role. He might be torn between his loyalty to the village and his belief in Naruto. Another could be Sasuke. He might react in different ways, either trying to help Naruto or seeing it as an opportunity to prove his own superiority.
Obviously, Naruto is the key character. He's the one taking on the council. But there could also be other characters like Kakashi, who might support Naruto in his endeavor.
In a Naruto council meeting fanfiction, there could be intense debates over the status of ninjas from other villages. For example, whether to allow them to enter Konoha for a joint training program.
One key element is the characters. You'd have the various devils, each with their own personalities and motives. Some might be power - hungry, others more diplomatic. Then there's the setting. The council meeting place, which is often depicted as a grand and imposing hall filled with dark magic and a sense of foreboding. Another element is the conflict. There could be internal conflicts among the devils, like disputes over resources or leadership, or external conflicts such as threats from other supernatural groups.
Obviously, Snape himself would be a key participant. Then there could be Lupin, as he's an important member of the Order. McGonagall might also be there, representing Hogwarts. And perhaps Moody, with his expertise in fighting the Dark Arts.
Hinata would also be important. Given her love for Naruto, she would be at his side constantly, providing emotional support. And Kakashi, as Naruto's former teacher, might offer his wisdom and experience in dealing with difficult situations like this.
Obviously Naruto would be one of the main characters since he is the one reporting the prank result. And the council members would also be main characters as they are the ones receiving the report.
Another character could be Kakashi. As Naruto's teacher, he might have some influence on how Naruto approaches the situation. He could either encourage Naruto to be more diplomatic or, if he also sees the council's wrongdoings, support Naruto in a more direct way. There could also be other ninja characters who are on the sidelines, observing this power struggle between Naruto and the council.
Some of the elders in the council are also very hated. They are usually portrayed as being old - fashioned and stubborn. They oppose any new ideas or changes that could potentially disrupt the status quo in Konoha. Their lack of understanding of the younger generation, like Naruto's generation, and their reluctance to adapt to new threats make them disliked in these fanfictions.
Harry Potter is often a central figure. His leadership and courage make him a natural part of any Gryffindor house meeting. He would likely share his thoughts on any important matters, whether it's about facing a new dark wizard threat or just how to improve the house spirit.
