It could be a misunderstanding. Padme might be forced to do something that seems like a betrayal. Suppose there is a powerful enemy who has kidnapped her family or something she holds dear. To protect them, she has to give some information about Naruto that could be used against him. Naruto, not knowing the situation, feels betrayed. This would create a complex and emotional plot in the fanfiction.
Well, one way could be that Padme is from a different ninja village and is on a secret mission. She gets close to Naruto to gain information about Konoha. When she gets what she needs, she betrays him by revealing his secrets or setting him up in a dangerous situation. For example, she could tell his enemies his fighting patterns or the location of his important allies.
Maybe Padme has been brainwashed by an evil force. In the fanfiction, this evil entity could be someone who wants to destroy Naruto's influence in the ninja world. Padme, under this influence, starts to act against Naruto. She could spread false rumors about him, causing his friends to doubt him at first. Then, she could lead him into a trap set by the evil force, making it seem like a betrayal.
One way could be that his parents were forced into it. Maybe they were under some powerful dark magic or mind - control that made them seem to betray Naruto. For example, an evil villain could have manipulated them to make Naruto think they don't care about him.
Perhaps his parents were part of a secret and evil organization all along. They pretended to be good but in fact were planning something big and Harry was just a pawn in their plan. So they betrayed him by leaving him exposed to danger or even trying to harm him directly. In the fanfiction, Harry could then go on a journey to discover the truth about his parents and their real motives.
In this fanfiction scenario, it could be that an enemy uses some sort of mind - control jutsu on Naruto's family. The family, under the control of this jutsu, doesn't recognize Naruto as their own and kills him. This would add an element of tragedy as Naruto would be killed by those he loves and trusts the most without them being fully in control of their actions. It would also open up the story for a revenge plot by Naruto's friends or other allies against the enemy who controlled his family.
Perhaps his parents were misled to believe that Naruto was a threat to the village. They might have been fed false information about Naruto being a potential danger, like being a vessel for a great evil. So, in an attempt to protect the village they loved, they made the tragic decision to kill him.
In a fanfiction where Naruto is the villain, perhaps he becomes corrupted by the Nine - Tails' power. The constant struggle to control the fox within him finally takes a toll, and instead of fighting it, he gives in. He then uses the Nine - Tails' brute strength to wreak havoc. He might see the shinobi world as a place full of hypocrisy and decides to 'cleanse' it by force, attacking villages one by one, starting with Konoha, which he now views as a place of false promises.
Naruto might initially feel disbelief. He's used to seeing the good in people, so Akeno's betrayal would be a huge shock. He could go into a state of self - doubt, wondering if he misjudged her all along.
Naruto might be angry at first. He is not one to take betrayal lightly.
His reputation in the ninja world could be damaged. If Padme spreads false information or reveals his secrets, other ninja might view Naruto differently. They could see him as a liability or a threat. This could lead to him being isolated in the ninja community, and he might have to fight harder to prove himself again.
Well, one way could be that Naruto inherits some of Zeus's powers like control over lightning, which he could then combine with his own chakra-based abilities. For example, he might be able to create super - powerful lightning - based jutsus that are far more destructive than his regular Rasengan. Another aspect could be the cultural clash. Naruto, coming from the Hidden Leaf Village in a ninja - based world, would have to deal with the very different world of Greek mythology where Zeus rules. He could be seen as an oddity, and this could lead to various adventures and conflicts as he tries to find his place in this new, strange world that is somehow related to his heritage.
One way could be that Naruto has been in a time - loop for a thousand years. He keeps reliving certain events, trying to change the outcome each time. For example, he might be trying to prevent a great war that keeps happening no matter what he does in each loop.
