In the 'Sirius Black adopts Harry' fanfiction, how would Sirius influence Harry's character development?

Harry would likely become more confident. With Sirius as his guardian, he'd have someone who truly believed in him from the start. Sirius was brave and rebellious, and these traits could rub off on Harry. He might be more willing to take risks and stand up for what he believes in earlier in life. For example, he might not tolerate the bullying from Draco as much as he did in the original story.

Sirius influences Harry's early life by being a protector. He stands as a shield against any potential threats. He might use his Patronus, a large dog, to guard Harry at night, making Harry feel safe in his sleep.

Their talk could also enhance Harry's magical knowledge. Sirius could teach him spells or magical techniques that he hadn't learned at Hogwarts yet. This new knowledge would be very useful for Harry in his fight against the Dark Arts. Moreover, learning from Sirius would make Harry more independent in his magical growth as he gets advice from someone outside of the school environment.

At first, Harry would likely be confused and scared. But this experience could force him to become more independent. He can't rely on Dumbledore or his friends at Hogwarts immediately. He has to learn to trust his own instincts and the bond he has with Sirius. This might make him more cautious in the future when it comes to trusting adults. For example, he might question Dumbledore's motives more often.

Well, it would likely make Harry feel extremely alone and betrayed. He already lost his parents, and Sirius was like a father figure. This could harden Harry, make him more distrustful, and he might become more self - reliant, not relying on others as much for emotional support.

Well, Harry would likely be more confident. With Sirius around, he has a strong male figure who believes in him wholeheartedly. This would make Harry bolder in his actions and decisions.

Sirius has a wild side. He could suggest having a room dedicated to pranks, filled with things like extendable ears and dungbombs (just for fun, not for actual use). Harry, being responsible, would be more concerned about the security of the flat. He'd make sure the doors and windows have strong locking spells. He might also want a study area that is quiet and organized for his studies and future plans.

It could develop in a complex way. The spanking incident might initially create tension between them. Harry could be angry or resentful towards Sirius at first.

Harry's character would likely become more confident. Living with Sirius, he'd have someone who truly believes in him. He might also become more rebellious in a good way, standing up to the unjust rules of the wizarding world like Sirius did. For example, he could be more outspoken about his views on the Ministry of Magic.
