What could be the reason for Harry Potter to yell at Fudge in fanfiction?

One possible reason could be a difference in opinion regarding the safety of the characters. Maybe Molly is being overly protective in a way that Harry feels is hindering their fight against the dark forces, so he yells in frustration.

Maybe Albus has done something dangerous or disobeyed Harry's instructions. For example, if Albus got involved with some dark magic related stuff without Harry's knowledge, that would surely make Harry yell at him.

Maybe Fudge was starting to turn against the wizarding community in more extreme ways. For example, if he was planning to persecute Muggle - borns more harshly or side with the Death Eaters secretly. Harry, being a defender of justice and equality in the wizarding world, would not tolerate such actions and might have been pushed to kill Fudge to stop his evil plans.

Maybe Harry finds out that Dumbledore knew more about his family's past than he let on. For instance, if Dumbledore had information about some dark secrets in the Potter family but didn't tell Harry, it could make Harry furious and prompt him to yell. Also, if Dumbledore's actions led to the death or harm of someone Harry cared about, like Sirius, Harry would likely be very angry with him.

One possible reason could be copyright infringement. If the fanfiction uses too much of the original 'Harry Potter' material without permission, it might lead to a lawsuit. For example, if it uses the exact same characters in a way that goes against the original concept or if it borrows major plot elements directly.

Well, in this fanfiction, Harry might finally stand up to Fudge in a really assertive way. Maybe he exposes all of Fudge's wrongdoings and incompetence in front of the whole wizarding community. For example, he could reveal how Fudge has been denying Voldemort's return and all the chaos that has ensued because of that denial.

One common theme is power and corruption. Fudge is often depicted as being power - hungry and making corrupt decisions in fanfiction, just like in the original books. For example, some stories show him using his position to suppress information or manipulate other characters for his own gain.

One possible reason could be that Mrs. Black has said or done something to endanger his friends. For example, if she reveals some secrets that put Ron and Hermione in danger, Harry might yell at her out of anger and protectiveness.

Maybe she's yelling at Ron. Their relationship in fanfictions can be quite complex. If Ron says something insensitive or does something stupid, like forgetting an important task that could put their mission in jeopardy, Hermione would surely yell at him.

It might signify her strong emotions. Hermione is a passionate character. Her yell could be a sign of her anger, for instance, if someone questions her intelligence or mocks her for being a 'Mudblood'.
