What could be the plot of a 'Percy Jackson Endgame' fanfiction?

It could be Kronos again, but in a more powerful and resurrected form. He might have found a way to come back even stronger after his previous defeat and now has a new plan to take over the world of gods and demigods.

A great plot could be that Thanos somehow discovers the power of the Greek gods and tries to steal it for himself. He starts by attacking Camp Half - Blood. The Avengers, who are aware of some strange energy signatures coming from that area, go to investigate. There they meet Percy and his friends. At first, there is mistrust, but they soon realize they need to work together. Percy and his friends help the Avengers understand the magic and powers related to the Greek gods, while the Avengers offer their high - tech weaponry and combat skills. They then embark on a journey to stop Thanos from achieving his goal, facing many challenges along the way, including some Greek monsters and Thanos' minions.

A great crossover would be Percy teaming up with Thor. Since Thor has his lightning powers and Percy has his demigod powers, they could combine their forces in a really cool way. Maybe Percy could use the water to conduct Thor's lightning, creating a powerful and unique attack. Also, Percy's knowledge of Greek mythology might give the Avengers some new insights into dealing with otherworldly threats.

A great plot could be Percy being sent on a top - secret mission by the army. This mission could be related to some ancient artifact that has military applications but also ties to his demigod world. Along the way, he meets other demigods who are also in the military for various reasons. Together, they have to overcome not only military enemies but also mythical creatures that are after the same artifact.

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.

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. Since he's a demigod, he might be seen as a powerful ally or a threat. He could end up using his knowledge of Greek mythology and his own powers to outwit the various factions in Alagaesia.

One possible plot could be that the entire Greek pantheon is thrown into chaos. Percy might be seen as a huge threat, and other gods and goddesses would either try to hunt him down or form alliances with him out of fear or a desire for power. Demigods would be forced to take sides, leading to massive battles among them.
