His parents could have taught him some advanced magic from a young age, which would make him stand out at Hogwarts in a different way than in the original story.
In some fanfiction, the idea of Harry Potter being betrayed by his parents might be justified through a complex web of magic and prophecy.

If Harry Potter snapped his wand in fanfiction, the plot could take a really interesting turn. Harry would be at a significant disadvantage. Enemies might see this as an opportunity to attack him.

Along the way, he would face numerous challenges and learn more about the deeper secrets of the wizarding world. This could also affect his relationships.
