Their relationship would likely become very close. Harry, who has always longed for a family, would finally have someone who truly cares about him like family. Sirius, on the other hand, would get to be the father - figure Harry needs. They would probably have a lot of heart - to - heart talks, sharing their joys and sorrows.
The 'Harry Potter' books are set in a magical world full of its own stories, prophecies, and secrets. Sirius is a complex character with a lot on his plate. He has to deal with his family history, his time in Azkaban, and his loyalty to his friends. Fanfiction is a form of creative writing by fans outside the original story. Sirius doesn't have the time or the inclination within the context of the story to be reading fanfiction. His life is too filled with real magical drama and danger.
Perhaps there could be a plot where Sirius and Harry team up to uncover secrets about the Dark Arts that are hidden in the Black family home. As they explore the old rooms and artifacts, they might stumble upon a powerful and dangerous object that the Death Eaters are also after. This would lead to a race against time to either destroy or protect the object while also fending off the Death Eaters.
One great fanfiction about Sirius' childhood could be one where it delves into his relationship with his family. Maybe it shows how he started to rebel against the pure - blood mania in his family at a young age. For example, he might have befriended a Muggle - born wizard secretly, which his family would have abhorred.
Well, if Sirius read fanfiction, it could open up a whole new side to his character. Maybe he'd start to question some of the things he thought were absolute in the wizarding world based on the creative ideas in fanfiction. But realistically, he has so much going on in his life - from trying to clear his name to protecting Harry - that it's hard to imagine him actually taking the time to read fanfiction. He's more of a doer in the real magical world than a consumer of fan - created fictional works.
One great fanfiction is 'James Sirius Potter: The Next Generation'. It shows James' adventures at Hogwarts, and how he deals with the legacy of his father Harry Potter. The story has great character development and interesting plot twists.
One great 'Harry Potter James Sirius Potter' fanfiction is 'The Next Generation's Adventures'. It beautifully portrays James Sirius Potter's character, showing his courage and mischievous side similar to his father. It also has great interactions with other Next - Gen characters like Albus and Lily.
Yes, there are likely many fanfictions where Harry Potter is depicted as living in Potter Castle. Fanfiction writers often like to explore different scenarios for their favorite characters, and having Harry live in his family's castle could be an interesting concept.
