Another plot twist could be that Percy discovers he has some hidden power or heritage as a result of the betrayal. For instance, he might find out that he has a connection to an ancient and powerful force that the gods were afraid of, which is why they betrayed him. This new power then becomes a key element in his journey to either seek revenge or prove his worth.
In some fanfictions, Percy's half - brother Tyson might be made to betray him. This could be due to being tricked by some sea monster that convinces Tyson that Percy is a danger to their kind. Also, Grover could be lured into a situation where he has to choose between saving the wild and betraying Percy. It often makes for a very heart - wrenching story as Grover and Percy have such a strong bond. Sometimes, the betrayal comes from an unexpected source like the gods themselves. They might use Percy as a pawn and then turn on him when he's no longer useful.
One aspect could be that in many Percy Jackson - related fanfictions, Percy being betrayed by the gods often leads to a complete shift in his character arc.

Well, one way Percy could be betrayed by the gods in fanfiction is if they break their promises to him. He has done a great deal for the gods, like saving Olympus. But if they don't fulfill their end of the bargain, like granting him certain protections or rewards, that would be a huge betrayal. Another way is if the gods side with his enemies for some political or self - serving reason, leaving Percy out in the cold.
One interesting plot twist could be Percy having to deal with the other gods' jealousy. Since he's a new king, the old gods might not be happy with his rule. For example, Zeus might try to undermine Percy's decisions. Another could be Percy using his new powers in unexpected ways, like creating new mythical creatures. And a third could be Percy facing a threat from an outside force that the old gods couldn't handle but as king, he has to find a solution.
Well, one plot twist could be that Percy kills the gods, but they are reborn in different forms. For example, Zeus is reborn as a young girl with all his powers intact. This would turn the whole story on its head as Percy now has to deal with these new incarnations of the gods he thought he'd defeated. And it could lead to a whole new set of adventures and challenges for him as he tries to figure out what to do with these reborn deities.
Another possibility is that Edward betrays Bella by revealing her secrets to their enemies.

Another could be that the Soul Society, which Ichigo has often helped, decides to turn on him due to some false accusations of him being too dangerous. Maybe they believe he is on the verge of losing control of his Hollow powers and decide to eliminate him before he becomes a threat to both the living world and the Soul Society.
One common plot twist could be that the person she trusts most, like her best friend, betrays her for power.
