In this fanfiction, it could be that Percy Jackson is forced into a martial arts tournament in the mortal world by some mischievous god. He has no prior knowledge of martial arts but he quickly adapts. He meets some interesting characters during the tournament, some of whom are also demigods in hiding. As he becomes a martial arts master throughout the story, he also uncovers a plot by an evil force that is using the tournament to gather power. He uses his newfound martial arts skills and his demigod powers to stop this evil force and save the day.
One possible plot could be Percy discovers a hidden martial arts dojo in the demigod world. He decides to train there and quickly becomes a master. Then he uses his new skills to fight off monsters in a more unique way, combining his water powers with martial arts moves.
Well, perhaps in the fanfiction, Percy is sent on a quest where he has to learn martial arts from an ancient master. As he progresses in his training, he realizes that martial arts can enhance his demigod abilities. He then has to face a powerful enemy that can only be defeated with his martial arts skills combined with his regular powers. He might start off as a novice in martial arts but through determination and his natural athleticism (from being a demigod), he masters it.
Another option could be a mortal martial arts master who unknowingly stumbles upon Percy. The mortal is a master of a rare and ancient form of martial arts. At first, he is hesitant to teach Percy because he senses something different about him. But as he gets to know Percy better, he realizes Percy's good heart and decides to train him. This would add an interesting dynamic as Percy has to balance his demigod life with his training under a mortal.
Well, it could be about Percy discovering new powers over water. Maybe he can control not just regular water but also things like water in plants or even in the clouds. He could use these new powers to defeat some really powerful ancient monsters that are immune to normal demigod attacks.
One possible plot could be that Percy, in an act of trying to prevent a war among the gods, decides to give Hera the master bolt. He might believe that Hera, as the queen of the gods, could be the most neutral party to hold it. This could lead to a series of events where other gods are either enraged or intrigued by his decision. For example, Zeus might see it as a direct challenge to his authority, while Athena might see it as a strategic move. Percy would then have to deal with the fallout of his actions, facing challenges from various mythological creatures sent by the angry gods and also trying to convince the other demigods that his move was for the greater good.
Nico di Angelo has a strong connection to the Underworld, so he's a prime candidate. He can already communicate with the dead and has some control over the shadows, which are related to death in a way. In fanfiction, he could be further developed to become the Master of Death, perhaps by making a deal with Hades or finding a hidden power within himself.
Well, the plot might start with Percy being sent on a special mission by the gods. They need someone with his quick reflexes and sharp eyesight to be a sniper. Along the way, he has to deal with the moral implications of taking lives from a distance. He might also face challenges in terms of getting the right equipment and training. His friends could be initially skeptical of this new role for him, but as they see him succeed in various battles, they come to accept and rely on his sniper skills.
One possible plot could be Percy using his bike to travel across the country to find and protect other demigods. He could encounter various monsters along the way and use his biker skills, like sharp turns and high - speed maneuvers, to evade them.
One possible plot could be that a powerful enemy, let's say a dark sorcerer, has found a way to use the powers of the Greek gods against the supernatural beings in the Mikaelson universe. Percy Jackson is sent to investigate and ends up getting caught in the middle of the Mikaelson family drama. He has to use his skills as a demigod and his knowledge of Greek mythology to help the Mikaelsons defeat this new threat while also trying to keep his own identity and mission a secret from some of the more untrustworthy members of the family.
Maybe Percy Jackson somehow gets transported to the world of Stranger Things and has to fight the Demogorgon. He could use his water - controlling powers to try and defeat it, like dousing it with a powerful stream of water.
Well, in a 'Percy Jackson Endgame' fanfiction, the plot might involve Percy finally having to make a huge sacrifice to save not just the demigod world, but the entire mortal world as well.

It could also include a race against time as some sort of dark prophecy looms over them.
The plot might involve Percy getting lost in Alagaesia. He then has to figure out how to get back home while also getting involved in the local politics and power struggles.
