The plot could involve an ancient artifact that the Avengers find. Unbeknownst to them, it has the power to summon a great evil from Percy Jackson's world. When this evil arrives, it starts to overpower the Avengers. Percy senses the disturbance and comes to the rescue. He and the Avengers must then work together to figure out how to send the evil back and keep the artifact safe, with Percy using his knowledge of ancient magic and the Avengers using their technology and superpowers.
Maybe the Avengers are under a curse that is slowly draining their powers. Percy, being a demigod, has some knowledge of curses. He hears about the Avengers' plight and decides to help. He embarks on a journey to find the source of the curse, facing many challenges along the way. Once he finds it, he uses his powers and the help of the Avengers (even with their weakened state) to break the curse and save them.
In a 'Percy Jackson Saves Tony Stark' fanfiction plot, Stark could be on a mission in a remote area that has some hidden mythological secrets. He unknowingly awakens an ancient evil. Percy Jackson, who is nearby on a quest of his own, notices the disturbance. He races to save Stark. Percy has to deal with his own personal demons as well as the new threat. He saves Stark by using his demigod powers in creative ways, like using the water in the environment to create shields or using his ability to read ancient languages to decipher a way to stop the evil. After that, they join forces to make sure the area is safe again and Stark is inspired by Percy's world to create new tech that can detect and deal with mythological threats.
Well, Percy could use his water powers to put out any fires or floods that the Avengers might be facing. His ability to control water could also be used to create barriers against enemies. For example, if the Avengers were up against a powerful fire - based villain, Percy could summon a huge wave to douse the flames and save the day.
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.
Well, initially, the Avengers would be quite skeptical. I mean, they deal with high - tech and super - soldier stuff. But once Percy shows what he can do, like summoning a giant sea monster to help in a battle, they'd start to see the value. Iron Man would likely try to find a scientific explanation for Percy's powers and might even try to replicate them in some way. Captain America would appreciate Percy's courage and how he uses his powers for good, just like he does with his own abilities.
One possible plot could be that the gods in the Percy Jackson universe sense a great threat from another dimension (the Marvel universe). Percy and his friends are sent to team up with the Avengers. Percy's water powers could be useful in fighting villains like Electro. Annabeth's strategic mind would assist in planning battles against foes like Loki. They all have to learn to work together, with Percy and the Avengers initially having some clashes due to their different ways of handling things.
One possible plot could be that in a world where the gods of Percy Jackson and the Avengers co - exist, Percy is somehow tricked or forced to banish the Avengers. Maybe there's a power struggle among the gods and they see the Avengers as a threat to their power, so they use Percy, who has a strong connection to the divine world, to get rid of them. Percy might be conflicted as he may admire the Avengers' heroism but has to follow the gods' orders.
Another option could be Black Widow. She's very good at adapting to new situations and using her skills in different ways. For Percy, who is coming from a very different world, she could teach him how to be stealthy and use his powers in a more covert way. She could also help him with understanding the political side of the Avengers, like dealing with government agencies and such, which Percy may not be used to in his world of demigods.
One possible plot could be that the Avengers mistake Percy Jackson for a dangerous threat. Maybe they've been given false information about his powers being uncontrollable. So, they decide to kidnap him to keep the world safe. But once they have him, they start to realize that he's not what they thought. Percy, being a hero in his own right, tries to convince them that he's on the side of good.
In such a fanfiction scenario where Percy Jackson is hunted by the Avengers, Percy would be at a huge disadvantage initially. The Avengers are a well - known and powerful group. However, Percy has his Poseidon - given powers. He could potentially use water sources around to create distractions or even defenses. The Avengers might be confused by his abilities which are so different from their own. For example, Iron Man's tech might not be fully effective against Percy's water - based attacks. It would be a really interesting story to see how Percy tries to outmaneuver the Avengers.
The Avengers would likely see Percy as a threat and try to stop him. There could be epic battles between Percy with his demigod powers and the super - powered Avengers. For example, Iron Man could use his high - tech weaponry against Percy's water - based powers.
