percy keeps the curse of achilles fanfic

Well, in this fanfic, perhaps there are unique interpretations of the Curse of Achilles. It could be that Percy discovers new aspects of the curse that weren't in the original story. For example, it might have some sort of connection to his demigod powers in a way that makes him even more special. Also, the fanfic might explore how Percy deals with the knowledge that he has this powerful and potentially dangerous curse.

In this fanfic, Percy's character could develop in several ways. Firstly, his understanding of power and responsibility might deepen. With the Curse of Achilles, he has a significant advantage, but also a great burden. He may become more cautious in his actions as he doesn't want to misuse the power of the curse. Also, his relationships with other characters may change. Some might be in awe of him, while others may be jealous, which could lead to him becoming more discerning about who he trusts.

There could also be antagonists. For instance, some old enemies of Percy might be drawn to him because of the Curse of Achilles. They might see it as a challenge or an opportunity to finally defeat him, and these antagonists would be important characters in driving the story forward.

Perhaps there's a plotline where Percy has to keep the curse a secret from his friends. This could lead to some tense moments of near - discovery and the resulting drama as he tries to keep his friends in the dark while still relying on them in battles.

It could be an old enemy of the gods who sees Percy as a threat because of the Curse of Achilles. Maybe a Titan who escaped from Tartarus and wants to use Percy's power for their own gain. If they can control Percy, they could have a powerful weapon against the gods.
