In this kind of fanfiction, Harry would likely grow up with a more hands - on and perhaps wilder form of parenting. Sirius was brave and impulsive. He might teach Harry some of his more unorthodox magic skills earlier. Harry would also be surrounded by Sirius' loyalty to his friends and family, which could shape Harry's own values in a different way compared to growing up with the Dursleys.
One possible plot could be that Harry grows up with a stronger sense of family. Sirius and Remus would teach him about his parents more directly. He might be more confident in his magic earlier, as they could start his training sooner. Also, he'd likely have a different view of werewolves and Animagi from an early age.
One possibility is that Sirius would teach Harry all about his family's history in a more private and laid - back setting in France. He might introduce Harry to different magical cultures unique to France, like the Beauxbatons Academy. Harry could grow up with a more carefree attitude, away from the prying eyes of the British wizarding world.
In such a fanfiction, Harry would likely grow up with a very different set of values and skills. Sirius, being a rebel and a bit of a wild card, would probably teach Harry more about the unorthodox ways of magic and the Marauders' secrets. Harry might be more confident and street - smart, having been exposed to Sirius' bold personality from a young age.
One possible aspect of this fanfiction could be how Sirius's unique personality shapes Harry's upbringing. Sirius is known for his rebellious and loyal nature. His influence might lead Harry to be more daring and less afraid of breaking the rules when it comes to fighting against the Dark Arts. For example, he could teach Harry some unorthodox defensive magic techniques that are not taught at Hogwarts.
Harry's personality would develop in a very different way. Growing up with Sirius and Remus, he'd be constantly surrounded by tales of the Marauders. This would make him more mischievous in a good way. He'd have a better understanding of the grey areas in life, as Sirius has a bit of a wild side and Remus has his own struggles. Harry would also be more independent, as Sirius and Remus would encourage him to think for himself and not blindly follow rules. He'd be more likely to question authority, especially when it seems unjust. And his sense of humor would be more developed, as Sirius is known for his jokes and pranks. Overall, he'd be a more well - rounded and confident young wizard.
Harry would likely be more confident. Sirius is a bold and brave character, and growing up with him would instill those qualities in Harry more strongly. He wouldn't be as meek as he was in the early days at Hogwarts.
