Harry's character may develop in terms of his trust issues. If he confronts the Order and uncovers some untruths or hidden motives, he might become more cynical about those around him. He could start to question everyone's intentions, not just the Order's. This could make him more self - reliant and less likely to blindly trust others in future situations.
In some fanfictions, Harry might initially be angry and feel betrayed when he confronts the Order. He could question their decisions and secrecy. For example, he might be frustrated about not being fully informed regarding the plans against Voldemort.
Harry's character could become more confident. With the new title of Lord Black, he has a certain status and power. This might make him less hesitant in making decisions. For instance, when dealing with the Ministry of Magic, he could be more assertive in demanding changes for the betterment of the wizarding community.
Harry Potter's character development is significant when he claims his lordship. He becomes more responsible as he has to handle the duties associated with his new status. He also becomes more assertive in dealing with the wizarding world's politics and power plays. His relationships might change too, as some may respect him more while others may envy or fear him.
Harry's character may develop a sense of mystery. Since he's allone, others don't know what he's up to. He might be exploring parts of the wizarding world that are not well - known. He could also become more brooding, constantly thinking about the challenges ahead and how to face them alone. He may develop new skills in secrecy, and his confidence could grow in a different way compared to when he was at Hogwarts surrounded by friends and mentors.
His character could become more confident in his charm abilities. After all, the Veela are known for their allure.
He becomes more responsible. Instead of getting into as many impulsive adventures, he focuses on his studies and the duties that come with being a student at Hogwarts.
His character might become more withdrawn. Slenderman's presence is often associated with solitude, so Harry could grow up being less social.
When Harry is raised by the Joker in fanfiction, his character development would be quite extreme. He'd start to embrace the Joker's values of chaos and anarchy. He might become desensitized to violence and suffering, seeing them as means to an end - that end being entertainment or causing disruption. His relationships would be based on power and manipulation rather than love or friendship. He'd constantly be looking for ways to outwit others and cause mayhem, losing any sense of innocence or goodness he might have had originally.
Well, Harry's personality would transform in many ways. In Hufflepuff, he'd be surrounded by people who value fairness and equality. This could make him more empathetic towards others. He'd also become more of a mediator perhaps, as Hufflepuff students tend to resolve conflicts in a peaceful way. His confidence might grow in a different direction. Instead of the Gryffindor - style bold confidence, it could be a quieter, more self - assured confidence based on his own efforts and the support of his Hufflepuff housemates.
His character might develop a sense of protectiveness. For example, he may start to see Sakura as someone worthy of his protection, which is a new feeling for him as he was previously more focused on his own goals in the Naruto universe. This could make him more empathetic towards others in general.
