Well, in this fanfiction scenario, it could be that Serafall is made to betray Naruto due to political reasons within the fictional universe. She might be pressured by her superiors or those in power to distance herself from Naruto. This could lead to a series of events where Naruto has to face not only the enemies he already had but also the consequences of Serafall's betrayal, like losing allies who were associated with her.
One possible plotline could be that Serafall, perhaps influenced by some external force or a misunderstanding, turns on Naruto. Maybe she believes Naruto has some hidden agenda that endangers her or her world. So she starts to undermine Naruto's efforts and even plots against him directly.
In this fanfiction concept, the betrayal could start small. Maybe Serafall starts to withhold information from Naruto that he needs to succeed in a certain mission. As time goes on, it escalates to her actively working against him. It could be related to a prophecy that she misinterprets, thinking Naruto will bring doom. So she decides to take matters into her own hands and betray him, which would then set off a chain reaction of events, with Naruto having to figure out why she turned on him and how to deal with the new threats that come his way.
Well, it could start with Anko being given false information about Naruto. Let's say someone convinces her that Naruto is secretly working with an old enemy of Konoha. She then starts to spy on Naruto. As she does this, she uncovers some things that seem to confirm the false information, but in reality, they are just coincidences or set - ups. So, she feels she has no choice but to betray Naruto to protect the village. It could also be that Anko has her own ambitions that conflict with Naruto's goals for the village, and she sees betraying him as a way to achieve her own ends.

He could start by using his shadow clones to create chaos and disrupt the normal operations of Konoha.
One possible plotline could be that Team 7 is influenced by an outside force, like a powerful enemy who has a way to manipulate their minds. They start to believe false information about Naruto that makes them turn against him. For example, they might be made to think Naruto is secretly working for their arch - enemies. Another plotline could be jealousy within the team. Maybe Sasuke gets jealous of Naruto's growing power and influence in the village and decides to frame him for something, causing the rest of the team to turn their backs on Naruto.
In a Naruto betrayed by friends fanfiction, a plot might involve Naruto's friends believing he's been corrupted by a new and powerful jutsu he's developed. They think it's changing him for the worse and decide to take action against him. This could lead to a big confrontation where Naruto is heartbroken at their lack of trust. Also, it could be that a secret from Naruto's past is revealed, and his friends, feeling deceived, betray him without really understanding the whole situation.
Well, it could be that Hestia betrays Percy for power. In the fanfiction world, she might see Percy as a threat to her own influence among the demigods or the gods.

Ash and Mewtwo then team up to fight against their betrayers and prove their worth.

Maybe Naruto's attempts to bring peace and unity among the villages are seen by Mei as him trying to gain too much power. So, she betrays him by spreading false rumors about him, which turns many against Naruto.
Well, in such a fanfiction, perhaps Naruto's godlike abilities start to have some unforeseen side effects that the village mistakes for him going rogue. His closest friends might be brainwashed into believing he's a threat, thus betraying him, and as a result, he gets banished. It could also be that an outside force manipulates the situation to get Naruto out of the village as he is too powerful a threat to their plans.
One possible plotline could be that Twilight discovers her best friend has been secretly working against her all along and planned something devious for the wedding.

Another could be that Twilight is betrayed by a new acquaintance who she thought was a friend, but in reality was an enemy in disguise, leading to chaos at the wedding.
