What are some plot ideas for a Harry Potter fanfiction where Harry is 3 years older?

Well, with Harry being three years older, perhaps he has already mastered some more advanced magic. In the fanfiction, this could lead to a different dynamic with his professors. For example, Snape might be more grudgingly respectful of his skills. Also, his relationship with Ginny could develop much sooner. They could be a power couple within Hogwarts, fighting side - by - side against the Death Eaters and helping to protect the school and the wizarding world in new and exciting ways.

In some fanfictions, the older brother could be an outcast from the wizarding world due to a misunderstood magical ability. He then takes Harry under his wing and shows him a different side of magic, one that is not taught at Hogwarts. They might go on adventures together outside of the school, exploring ancient and forgotten magical places, and in the process, the older brother helps Harry become a more well - rounded wizard.

Well, a great plot idea could be centered around a thousand - year - old prophecy that is just now coming to fruition. The characters in the fanfiction could be on a quest to either fulfill or prevent this prophecy. Or perhaps it could be about a secret society that has been operating for a thousand years and how it affects the current state of the wizarding world in the Harry Potter universe.

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.

The plot might revolve around the older sister being a part of a prophecy too. Just like Harry, she has a special destiny. But instead of being in the spotlight like Harry, she works behind the scenes to ensure Harry's success in the fight against Voldemort. She could be the one who finds out about Horcruxes first and guides Harry in that direction, all while dealing with her own challenges at Hogwarts, like trying to keep her identity as Harry's sister a secret from the wrong people.

One idea could be exploring the next generation's adventures at Hogwarts. Maybe they discover a long - forgotten spell that causes chaos in the school. Another could be a mystery involving a new dark wizard who is secretly targeting the children of the original heroes.

Well, there could be a story where an older witch who was once a friend of Lily Potter returns to the wizarding world after years of self - exile and becomes like a surrogate mother to Harry. Or a fanfiction where an older female character who was part of an ancient magical order teaches Harry about some forgotten magic that could be useful in his fight against the dark forces. Also, a story about an older Hogwarts house - elf who has been around for generations and gives Harry some unique insights into Hogwarts' hidden secrets.

One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.

One plot idea could be that HK - 47 gets teleported to the Harry Potter world. He then starts to analyze the magic there as if it was a new form of technology. He tries to find ways to use magic to upgrade himself. Meanwhile, Harry and his friends are both intrigued and a bit scared of this strange mechanical being. They have to decide whether to trust him or not, especially when they find out that some dark wizards are also interested in HK - 47's abilities.

One idea could be that Cedric, having survived, becomes a key figure in the fight against Voldemort. He might use his popularity and influence among the students to unite them against the Dark Arts. For example, he could start a secret dueling club where students practice defensive spells in preparation for potential attacks from Death Eaters.
