Perhaps Tony Stark's sense of self - sacrifice led to his 'betrayal'. He might have believed that by taking a certain action that others would consider a betrayal, he could prevent a greater disaster. His over - confidence in his own plans could also play a part. He thought he had a foolproof plan to save the day, but it involved actions that went against the trust of his comrades.
He could have been betrayed first. Maybe his friends or the Avengers turned on him in some way, and in his anger and hurt, he retaliated in a way that was seen as a betrayal. It's also possible that he was misled by false information. He thought he was doing the right thing, but it turned out to be a betrayal because the information was wrong. For instance, he might have been told that a certain action would save the world when in fact it was harmful.
One possible reason could be that he was forced to betray under some kind of mind control. Maybe an enemy like Hydra got hold of him and made him do things against his will. Another reason might be that he was trying to protect something or someone he loved in a very extreme way that seemed like a betrayal to others. For example, he might have made a deal with a villain to keep Pepper safe.
Steve Rogers would probably be deeply disappointed. He values loyalty highly, and Tony's betrayal would shatter the trust they had. He would try to find out the reasons behind it and might even try to bring Tony back to the right path if he thought there was a chance.
Maybe he doesn't fully understand his powers yet. Tony Stark is a scientific genius, but new powers might be beyond his current understanding. He could be worried that if he reveals them too soon, he won't be able to control them properly and might cause harm. So, he chooses to hide them while he studies and figures them out.
One possible plot reason could be ideological differences. Tony Stark is often portrayed as a tech - savvy capitalist, while Steve Rogers has more traditional values. Their views on how to protect the world, like Tony's preference for high - tech solutions and Steve's leaning towards more human - centered approaches, might drive them apart to the point of divorce in the fanfiction.
One possible reason could be a disagreement over superhero tactics. Peter, being young and idealistic, might yell at Tony if he thought Tony's methods were too extreme or not in line with his own sense of justice. For example, if Tony made a decision during a battle that put civilians at risk, Peter would likely be very vocal about it.
Another possibility is that he underestimates the importance of family. Tony has always been focused on his own achievements and the big - picture stuff. He might not realize how much his daughter needs him until it's too late.
Maybe he's too caught up in his work. Tony Stark is often depicted as a workaholic, so he could be so focused on his inventions and saving the world that he simply doesn't have time for his son.
Maybe his own self - centered nature plays a role. Tony Stark has always been a bit of a playboy and a genius focused on his own projects. His daughter might seem like an afterthought compared to his latest invention or business deal.
Maybe he realizes that the cost of being Iron Man is too high. His suits are constantly damaged, and he has to deal with numerous enemies. This could lead to him quitting in the fanfiction to avoid further harm to himself and those around him. For example, his suits might put Pepper Potts in danger, so he decides to stop.
Well, it could be that Naruto's friends are influenced by a dark power. This power could twist their perception of Naruto, making them see him as a threat instead of a friend. Or perhaps there's a prophecy that Naruto is supposed to be the cause of some great disaster, and his friends, in an attempt to prevent it, decide to betray him. It's also possible that a new character enters the story and sows seeds of discord among them, leading to the betrayal.
One possible reason could be jealousy. Maybe someone in Ash's group is jealous of his skills or popularity. For example, if there's a character who always feels overshadowed by Ash, they might betray him out of envy. Another reason could be a misunderstanding. Perhaps Ash was misinterpreted while making a crucial decision, and that led to the betrayal.
