Well, perhaps in this fanfic, since he's raised by Charlus Potter, there could be a plot where Harry has a different set of friends compared to the original story. He might be more involved with an older, more sophisticated wizarding crowd, which leads to different adventures and challenges. For example, he could be introduced to high - level magical politics at a young age.
In such a fanfiction, perhaps Harry would grow up with a different set of values. Charlus Potter might instill in him a more traditional pure - blood wizarding family's values. He could be trained in advanced magic from a very young age, having access to family secrets and spells that he didn't get in the original story. This could make Harry a more powerful and confident wizard earlier on, and his relationships with other characters like Ron and Hermione might develop differently as his upbringing shapes his personality in a new way.
One possible plotline could be that Charlus Potter imparts unique magical knowledge to Harry. Since he's from an older generation, he might teach Harry some long - forgotten spells or magical traditions. Another could be that Harry grows up with a different social circle, perhaps more connected to the old pure - blood families through Charlus. And also, Charlus might train Harry in a more traditional and strict way of magic compared to what Harry would have experienced at Hogwarts with Dumbledore.
Harry might be more self - assured. Charlus, being from an older time, could have a more no - nonsense approach to teaching Harry magic. This would make Harry more confident in his abilities. For example, he might not second - guess himself as much as he does in the original story.
If raised by Charlus Potter, Harry's character would be shaped by the values of an older wizarding generation. He might be more formal in his manners and speech. He could also be more interested in the history of the wizarding world, as Charlus would likely instill in him a respect for the past. This could lead to Harry being more of a diplomat among different wizarding groups. His sense of justice might still be strong, but it could be influenced by the more traditional views of his new family environment. For example, he might approach issues like the treatment of house - elves or the status of werewolves in a different way, based on the values he has been taught by Charlus.
