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.
Well, in this fanfiction, there could be a plot where Harry's upbringing by Charlus Potter changes his personality. Maybe he becomes more confident earlier because Charlus instills a sense of pride in his family heritage. Also, there might be a situation where Harry has to deal with different enemies or threats from the very beginning. For example, enemies that Charlus had made in his own time might target Harry as a way to get back at Charlus.
One possible plotline could be that Charlus Potter imparts some long - forgotten family magic or knowledge to Harry. This knowledge could help Harry in his fight against Voldemort in a different way than in the original books. Another plotline might be that Charlus Potter is brought back from the past through some time - travel mishap, and he has to adapt to the modern wizarding world while also guiding Harry. Or, it could be that they meet in a dream - like realm, and Charlus gives Harry cryptic messages about his future and the Potter family's true destiny.
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.
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.
One possible plotline could be that the Potter elves teach Harry unique magic that is different from what he would learn at Hogwarts. For example, they might show him ancient elf magic that gives him an edge in dealing with dark forces. Another could be that the elves raise Harry with a strong sense of family and loyalty, which makes him more empathetic towards those who are often overlooked in the wizarding world, like house - elves themselves.
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.
One interesting plotline could be their adventures in the wizarding world together. They might discover hidden magical secrets or face dangerous dark forces as a team.
Obviously, Harry and Charlus Potter are the main characters. Harry as the one being raised, and Charlus as the one doing the raising.
One possible plotline could be Harry learning dark magic in Hell but then using it for good in the wizarding world. For example, he might master a powerful spell that can only be learned in Hell to defeat Voldemort once and for all.
One possible plotline could be Harry being raised by characters from a different magical universe, like the Narnia characters. This might lead to him having a very different understanding of magic and his role in the wizarding world. Another could be if he was raised by characters from a superhero universe, which would likely result in him having some unique combat skills in addition to his wizardry.
One interesting plotline could be how Harry's personality is shaped in a very different way compared to the original series. Maybe he becomes more street - smart and less trusting due to the influence of the'slashers'. Another could be the new magical abilities or skills he might develop under their guidance.
