In the fanfiction, Harry can express his anger through his actions towards the objects around him. He might slam his hand on a table, making things on it jump. He could also storm out of a room, leaving others in shock. When it comes to verbal expressions, his voice can become hoarse from shouting and his words can be sharp and cutting, especially when he feels betrayed or wronged.
He might lash out with his magic. For example, he could send a spell flying at the source of his anger without really thinking. Sometimes, he just glares intensely, his green eyes filled with fury. And he may raise his voice, shouting at those who have angered him.
In the 'Harry Gets Angry' fanfiction, Harry might get angry when his reputation is smeared. He has always been in the spotlight, and false rumors can really get to him. Also, seeing the weak or the underdogs being bullied can make him angry. He has a strong sense of justice, so any form of oppression or unfair treatment towards others can stir his anger as well.
He could also distance himself from them. Naruto might choose to avoid his family, not wanting to be around them as a way to show his anger. He could move out or stop participating in family activities.
She might start by giving them the silent treatment. Just ignoring them completely when they try to talk to her, which would be a very human way of showing anger.
It could be due to a misunderstanding. Perhaps someone spread false rumors about him, and as a result, people started treating him differently. He might be angry at everyone because he feels that no one bothered to find out the truth from him. Also, if there were some new rules or restrictions imposed on him without proper explanation, that could fuel his anger.
It could lead to a lot of conflict. His friends might try to reason with him, but if he's too angry, he might push them away. This could split their group apart, creating new alliances or just leaving Harry isolated for a while. His anger can also attract the attention of the wrong sort of people, like those who want to use his emotional state for their own gain.
He might be confused at first. Harry isn't always the quickest to understand Hermione's motives right away. So he could just stand there, looking at her with a puzzled expression on his face, not really knowing what he did wrong.
He might directly confront her. Naruto is not one to hold his tongue, so he could just barge into Tsunade's office and start yelling about why he's angry. For instance, he could say 'Tsunade - sama, your decision was wrong and it's going to hurt a lot of people!'
He often expresses his anger through sarcasm. For instance, when dealing with pompous colleagues or superiors, he uses sarcastic remarks to show his disdain.
His anger often manifests physically. His muscles might bulge more than usual, and his hair could stand on end even more in his Super Saiyan forms. His ki, or energy, also becomes more visible and intense. It's like a red - hot aura surrounding him.
Well, Harry is known for his loyalty to his friends. So when they try to testify against him (maybe under some kind of spell or false evidence), he could get really angry. He might start pacing back and forth in the courtroom, his fists clenched, and then turn to his so - called friends and say in a cold, angry voice 'I thought you knew me better. How could you believe these lies?' His anger would be a mix of betrayal and the general unfairness of the trial situation.
