One interesting plotline could be the development of a new magical ability in the White Knight that helps Harry and his friends in their fight against Voldemort. For example, the White Knight might discover a way to manipulate time in a small area, allowing them to undo some of Voldemort's recent evil deeds.
Perhaps a plotline where the White Knight has to face a moral dilemma. Say, they find a powerful dark artifact that could potentially be used to defeat Voldemort, but using it would also corrupt them. This internal struggle can add depth to the character and the story.
One interesting plotline could be the transformation of a character into Death's Knight and how they struggle with the new powers and the dark nature it might bring. For example, they might have to fight against their own former friends who now see them as a threat.
Another potential enemy could be a group of pure - blood supremacists who don't like the idea of the White Knight, who might be a symbol of change and equality in the wizarding world. They would try to undermine the White Knight's efforts to make the wizarding world more inclusive.
In some fanfictions, Harry Potter having white hair could be a result of a time - travel mishap. Maybe he travels back in time and something goes wrong, which alters his physical appearance, specifically his hair. This could lead to all sorts of interesting scenarios. For example, he might be mistaken for a different person in the past, or his friends in the present might not recognize him when he returns. It could also create a whole new dynamic with his relationships, as people react differently to his new look.
One interesting plotline is when Lily is given the chance to change the future. In some fanfictions, she has the power to go back in time and make different choices, like whether to marry James or not. Another is when she discovers hidden magic within herself that no one else knew about. This often leads to her having to face new challenges and enemies.
One interesting aspect could be the reimagining of Harry Potter in a knight - like role. It might involve him having chivalrous adventures, perhaps saving Hogwarts in a more medieval - style way, with swords and shields instead of wands. He could be part of a knightly order within the wizarding world, adding a new layer of fantasy to the story.

Well, perhaps in this fanfiction, the Phoenix plays a role in revealing hidden secrets about Harry's family.

This could then set him on a new quest, different from the one in the original books, and change the course of the story completely.
A common plotline is the characters' post - graduation plans. Some fanfictions might explore how Harry, Hermione, and Ron decide on their career paths. Maybe Harry is conflicted between becoming an Auror or a teacher at Hogwarts. Hermione could be considering further studies in ancient magic, and Ron might be thinking about joining his brothers in the joke shop business. This exploration of their future dreams and how they support each other during this transition period can be really engaging.
A possible plotline could be a time - travel fanfiction where Harry and his friends accidentally travel back in time to the era when the founders of Hogwarts were alive.

This would involve dealing with the different magical cultures and practices of that time, as well as the complex personalities of the founders.
One interesting plotline could be the brothers having a secret mission within Hogwarts that the original books didn't cover.
