You can start by looking on popular fanfiction websites like FanFiction.net. It has a large collection of Harry Potter - related fanfictions, and there's a good chance you'll find some great Charlus Potter ones there.
One great fanfiction could be 'The Lost Tales of Charlus Potter'. It delves into his adventures at Hogwarts, his friendships, and how he might have influenced the wizarding world before Harry's time. Another is 'Charlus Potter: The Early Years' which focuses on his family background and how he grew up in the Potter family.
One key element is often the exploration of family ties. Since Charlus Potter is related to Harry, fanfics usually dig into how the family's past actions and secrets impact the present. For example, in many fanfics, Charlus's relationships with other prominent wizarding families are explored.
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.
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.
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.
Well, the 'Wrong Boy Who Lived - Charlus Potter' concept often involves reimagining the prophecy and the roles of the characters. Maybe there are hidden secrets or different circumstances that make Charlus the supposed 'chosen one' instead of Harry. It adds a new layer of intrigue to the Potterverse.
One great 'Harry Potter Charlus Potter' fanfic is 'The Legacy of Charlus Potter'. It delves deep into the untold stories of Charlus Potter and his connection to the main Harry Potter storyline. It has really well - developed characters and a plot that keeps you hooked from start to finish.
