What are some interesting plot ideas for a 'Percy Jackson Master of Water' fanfic?

In a fanfic, perhaps Percy and his friends accidentally stumble upon Medusa's lair while on a quest. But instead of immediately attacking, Medusa offers them a deal. She says she will give them a valuable clue to complete their quest if they help her get revenge on one of the minor gods who wronged her in the past. Percy and his friends then have to decide whether to trust Medusa or not.

One idea could be Percy discovers a new power related to fire that was dormant within him. Maybe it was a gift from an ancient and forgotten god. He then has to learn to control it without the help of his usual mentors like Chiron.

In 'Percy Jackson Master of the Hunt' fanfiction, a plot could revolve around Percy being sent on a mission to rescue a group of hunters who have been captured by an ancient evil. Along the way, he has to use his wits and his powers in new ways. He might have to learn some of the more obscure hunting techniques from the other members of the hunt. And as he progresses, he uncovers a conspiracy that threatens not only the hunt but the entire world of demigods. This would put him in a position where he has to make difficult decisions and use his leadership skills as the Master of the Hunt to save everyone.

Another plot could involve Percy's friends getting accidentally transported to a different realm in the Percy Jackson universe. They have to rely on their friendship and the skills they've learned from Percy to survive and find their way back. For example, they might end up in the Underworld and have to navigate past various challenges without Percy at first.

One idea could be a mortal accidentally stumbling into Camp Half - Blood and having to adapt quickly to the world of demigods. Maybe they have some hidden power that only reveals itself in this new environment.

One idea could be to create a new quest within the game world. For example, Percy and his friends have to retrieve a powerful artifact that was stolen by a new type of monster. This could involve exploring new areas of the game, like a hidden underwater city that has never been discovered before. Another plot could be a tournament in the game where demigods from different cabins compete against each other in various challenges. This would show off their different skills and powers. A third idea is that there's a glitch in the game that's causing real - world problems in the Percy Jackson universe, and they have to figure out how to fix it before it's too late.

One plot idea could be Gaea's redemption. In the original series, she was a major villain, but in a fanfic, she could be given a chance at redemption. Maybe Percy and his friends discover that Gaea was being controlled by a more powerful and malevolent force all along, and they have to work with her to defeat this greater evil.

In a Percy Jackson Tartarus fanfic, a great plot could be centered around Tartarus corrupting the very essence of Percy's powers. He starts to lose control of his water - based abilities and instead they become tainted with the darkness of Tartarus. Percy then has to go on a journey within Tartarus to find a way to cleanse his powers, all while being hunted by the most dangerous creatures that lurk in the abyss.

A really interesting plot would be if Percy lost his memory and ended up in a mortal town. He has to figure out who he is on his own while still being hunted by some old enemies. The gods are aware of his situation but can't interfere directly because of some ancient rule. So Percy has to rely on his instincts and any small clues he can find about his past to get back to his normal self and his life at Camp Half - Blood.

One idea could be that Hylla and Percy team up to rescue a group of demigods captured by an ancient monster. They use their combined powers and wits to outsmart the beast.
