Well, in some fanfictions, Percy's time control allows him to visit different eras of the demigod history. He might go back to the time of the first Olympians and interact with them, which could lead to all sorts of interesting plot twists. Also, he could use his power to speed up time in a training session to quickly gain new skills. Or, in a more romantic fanfic, he could use time control to have more time with his love interest, like creating a time - stopped moment for a special date.
A great fanfiction idea could be Percy using time control to save a friend who was lost in time. He might have to navigate through different time periods, facing the challenges of each era. For instance, in the time of the dinosaurs, he has to avoid being eaten while looking for his friend. In another scenario, he could use time control to study ancient magic that was lost over time. By freezing time in the library of the gods, he can read all the forbidden books and learn powerful spells to help his friends in the present.
One example could be a fanfiction where the character relationships are completely distorted. For instance, if in the original Percy Jackson series, Percy and Annabeth have a strong, positive relationship, but in the broken fanfiction, they are constantly at odds for no good reason. Another might be a fanfiction that completely changes the rules of the demigod world, like making it so that demigods no longer have powers related to their godly parent. This disrupts the whole essence of the original story.
One great example is 'The Trials of Percy Jackson: Reborn'. In this fanfic, Percy has to face new and even more powerful foes, with his powers evolving in unexpected ways. It's full of intense action scenes and great character development.
Some funny Percy Jackson fanfiction involves the characters swapping powers. Percy gets Annabeth's wisdom and she gets his water - controlling abilities. Percy is suddenly spouting out facts and Annabeth is accidentally making it rain inside the cabins. There are also stories where the demigods enter a cooking competition at camp. Percy tries to make a fish dish but ends up with a mess as the fish keep jumping out of the pan and onto people's plates. Nico, who has no idea about cooking, accidentally creates a dish that has a strange magical effect and makes everyone who eats it start singing old sea shanties at the top of their lungs.
A good Percy Jackson exhausted fanfiction might involve Percy being worn out from constantly having to deal with new threats to the demigod world. Maybe he's been fighting multiple monsters in a row without much rest. In the fanfic, he could start having nightmares about all the battles. His exhaustion could lead to him making mistakes in training, which frustrates him even more. Writers often use this kind of situation to show Percy's vulnerability and how he's still just a teenager, even though he has all these great powers and responsibilities.
One good 'Betrayed Percy Jackson' fanfiction is 'The Fallen Hero'. In it, Percy is betrayed by his so - called friends at Camp Half - Blood who believe false rumors about him. Another is 'Alone and Betrayed' where Percy is framed for a crime he didn't commit and has to fend for himself. There's also 'Betrayal's Aftermath' which shows Percy's journey of rebuilding his life after the betrayal.
Well, in this fanfiction, Percy controlling the Styx could lead to some really interesting plot developments. Since the Styx has such a significant role in Greek mythology, it could attract all kinds of mythical creatures and gods. Percy could find himself in the middle of a power struggle as different factions either try to use him or stop him. He might also use the Styx to travel to different realms or access hidden knowledge. And perhaps he would have to face the consequences of messing with such a powerful and sacred entity, like facing the wrath of Hades or other underworld deities.
One consequence could be that Percy gains a lot more respect among the demigod community. Controlling Typhon is no small feat, so he'd be seen as an even greater hero. Others might look up to him more and he could potentially become a leader in a more significant way.
One interesting plot twist could be that Percy's control over the ocean is suddenly taken away by a dark magic spell. Then he has to find a way to get it back, perhaps by going on a quest to find a long - lost artifact or by making a deal with a mysterious sea - dwelling being. Another twist might be that the ocean starts to rebel against Percy's control. The sea creatures turn on him, and he has to figure out why and how to fix it.
One great example could be a story where Percy travels back in time to the era of the Greek gods' creation. He might witness the birth of Mount Olympus and interact with primordial deities. This would add a whole new layer of adventure and discovery to his character arc.
One possibility is that Percy uses his time - controlling ability to prevent a great disaster in his world. Maybe he goes back in time to stop an evil force from being unleashed in the first place.
