One possible fanfiction could be about Harry being 3 years older and already having a more advanced understanding of magic. He might start to question some of the Hogwarts traditions earlier and try to bring about changes. For example, he could be more involved in the politics of the wizarding world and use his fame to advocate for better treatment of house - elves.
There could be various storylines involving Heather as an older sister in Harry Potter fanfiction. Maybe she's a Gryffindor like Harry and helps him out in his adventures, or she could be a Slytherin with her own complex motives.
Well, he could be more independent and decide to explore the Forbidden Forest on his own more often. He might discover new magical creatures that were previously unknown to Hogwarts students. This could lead to him getting into trouble with the teachers, but also make him a bit of a hero among his peers.
One great older Harry Potter time travel fanfiction is 'The Time - Turner Conundrum'. In this story, Harry accidentally travels back in time much further than he intended. It's full of interesting twists as he has to deal with a Hogwarts that's very different from what he knows, and he has to figure out how to get back to his own time without changing history too much.

Often, older women in these fanfictions are protectors. They use their magic and experience to safeguard the younger characters, like Harry and his friends. They may also be the keepers of secrets. With their long lives in the wizarding world, they hold onto information that could be crucial for the development of the story. Moreover, they tend to have a deep connection to the history of Hogwarts and the wizarding world in general, which gives them a unique perspective on current events.
There's 'The Changeling' in the realm of Harry Potter older fanfiction. This story takes a different look at the wizarding world's history and how it might have affected the present day in the series. It has a unique take on the magic system. Also, 'After the Battle' is a great read. It shows the post - war Hogwarts and how the characters are dealing with the aftermath of the great battle, including Harry's role in rebuilding the school.
The writing style matters a great deal. It should be descriptive enough to bring the world and characters to life. If it's just a bunch of flat statements about the harem relationships, it won't be interesting. A good writer will use dialogue effectively to show the interactions between Harry and the members of his harem. Also, the pacing should be right. It shouldn't rush into the harem part too quickly but build up the relationships over time, similar to how J.K. Rowling built the relationships in the original series.
If Harry was three years older, he would be more mature physically and mentally. This could mean he is less likely to be bullied by Dudley, as he would be stronger and more assertive. At Hogwarts, his academic performance might be even better as he has had more time to study independently before coming to school. His relationships would also be different. For instance, his friendship with Ron and Hermione might have a different start, as he would be more self - assured and might approach them in a different way.
Older Harry Potter fanfic often has a more in - depth exploration of the original story's lore. Since they were written earlier, they might have different interpretations of the characters compared to more recent ones. For example, they might portray Hermione in a more traditional 'book - worm' way. They also tend to have a different writing style, sometimes more descriptive and less action - packed.
