What are some interesting plot ideas for 'Percy Jackson the Lone Hunter' fanfiction?

Here's a more complex plot. In the fanfiction, Percy discovers that there's a prophecy related to the Hunters of Artemis that could change the balance of power between the gods. He's drawn into this mystery as the Hunters suspect he might be the key to either fulfilling or preventing the prophecy. Along the way, he forms an unexpected bond with one of the hunters, which causes some internal conflict among the group, as they have sworn off relationships with males. This would create a lot of drama and interesting character dynamics.

One idea could be that Percy, as the lone warrior, has to face a new threat alone. Maybe a powerful and ancient monster that has been awakened and no one else believes in its existence at first. He has to rely on his own skills and the limited resources he has.

One plot idea could be Percy having to team up with Hera to rescue a group of demigods who have been captured by an ancient monster. Hera, despite her usual aloofness, realizes she needs Percy's unique skills.

The Titans could still be a threat. Even though they were mostly defeated, there could be some remnants or new Titans emerging. For example, a Titan who was in hiding and now sees Percy as a threat to his plans of taking over again.

Well, it could be about Percy going on a solo quest to find a powerful and lost artifact. Maybe he has to face some new and dangerous monsters all by himself, like a horde of fire - breathing dragons that guard the artifact in a hidden lair.

One idea could be Percy and his friends getting trapped in a virtual game world that's a twisted version of their own. They have to use their demigod skills to defeat the digital monsters and find a way out.

Maybe Percy is sent on a quest to Atlantis because there are rumors of a traitor among the Atlanteans who plans to side with the Titans. Percy has to navigate the complex political situation in Atlantis and figure out who the traitor is before it's too late. He also has to deal with the Atlantean magic which is different from what he's used to.

One idea could be that Percy discovers a hidden realm within the world of the Wanderer. This realm has its own set of rules and challenges that he has to navigate. Maybe he meets new demigods there who have been lost for centuries.

One idea could be Percy having to make a deal with a minor underworld god to save Annabeth from a new and strange curse that's slowly draining her life force. He has to complete a series of tasks in the underworld that test his loyalty and courage more than ever before.

Well, perhaps the shield was once owned by a powerful demigod from the past. In the fanfiction, Percy starts having strange dreams about this demigod and the shield's true origin. As he investigates, he realizes that the shield holds the key to defeating a new, emerging evil that threatens not just Camp Half - Blood, but the entire world of gods and mortals. So, he has to figure out how to unlock the shield's full potential.
