One interesting plot twist could be that a character thought to be an enemy turns out to be a long - lost ally. Maybe a cursed book reveals a prophecy that changes everyone's perception of the character's true nature.
A great plot twist could be related to the origin of the cursed books. Perhaps it's revealed that they were created by a former hero who went rogue, not by an obvious villain.

One interesting plot twist could be a character who was thought to be an enemy turns out to be a secret ally. For example, a minor god who was initially seen as working against the demigods actually has a hidden agenda to protect them from a greater threat that the main Olympians are unaware of.
Perhaps a plot twist where Percy discovers that his own powers are somehow linked to the Bane in a way he never expected.

A possible plot for this fanfiction is that the curse makes Percy lose his memory bit by bit. He forgets his friends, his past adventures, and even his own identity. As he struggles to figure out what's wrong with him, he starts having strange visions that are both a clue to the curse and a danger in themselves. Maybe the gods who cursed him are trying to erase him from existence, and he has to rely on his instincts and the few remaining memories to fight back. He might meet new characters who are either trying to help him or are part of the gods' plan to keep him cursed.
Annabeth Chase would also be a main character. Her intelligence and strategic thinking are important assets, and she would be involved in trying to figure out the secrets of the cursed books. And Grover, Percy's satyr friend, he's always there to help Percy, so he's likely to be a main character in the fanfic too. He might use his nature - sensing abilities to detect something unusual about the cursed books.
One interesting plot twist could be that the Minotaur is actually a misunderstood creature under a curse.

For example, he might be able to communicate with the Minotaur's mind and find out its true motives.

Well, in some fanfics, a plot twist might be that Voldemort has a secret heir who surfaces in the 'Cursed Child' era.

It could lead to some really creative solutions and alliances that were not possible before.
Well, one interesting aspect could be the unique twists on the original mythology. For example, in some cursed fanfiction, the gods might have different and darker personalities.

In the stories, the revelation about Luke being a traitor is a big plot twist. He was initially seen as a friend and mentor to Percy. But later, it turns out he has his own dark motives and is working against the gods, which adds a lot of complexity and danger to the story.
