In this fanfic, Percy might be seen as an outcast at first among the Avengers because he's so different. But as time goes on, they come to respect his abilities. The story could also explore how Percy's presence affects the dynamics within the Avengers. Does he create new rivalries or alliances? And how does he adapt to their high - tech world when he's used to the more ancient and magical world of the Greek gods? Maybe he even tries to introduce some of his own magic into their technology, leading to some interesting and unexpected results.
Well, he could bring his unique water - controlling abilities to the Avengers. Maybe he'd be the one to put out the fires during big battles in the city. He might also form an interesting friendship with Thor, since they both have some connection to powerful elements.
Percy could also be a big fan of Hulk. Just like Percy has his own 'inner beast' that he sometimes has to control (his demigod powers), Hulk has his own anger issues. Percy might see a bit of himself in Hulk and also be in awe of Hulk's raw strength. He would probably be interested in seeing if there's a way to help Hulk better control his rage, using his own experiences of self - control.
Well, it could be that Peter starts off as a regular guy who is just a huge fan of the Avengers. Maybe he follows all their news, collects their merchandise. One day, he gets a chance to meet them somehow, like through a Stark Industries internship. Then he gradually proves himself useful to them and they start to train him. Eventually, he becomes part of the team, with his own unique skills like his spider - powers adding to the Avengers' strength.
Well, perhaps Harry discovers the Avengers through some magical means like a spell gone wrong that transports him to the MCU world. He could be in awe of their powers and decide to learn from them, and then try to incorporate their fighting styles into his own magical battles.
Another idea is that Percy discovers he has a long - lost vampire heritage. As he becomes a vampire, he starts to unlock memories and powers related to his vampire lineage. He could go on a journey to find out more about his vampire ancestors and the secrets they held, all while adjusting to his new vampiric existence which is full of both challenges and newfound abilities.
Perhaps Percy is pushed to his limits by some great injustice in the story world. Maybe he witnesses the death of someone he loves at the hands of an evil force. This trauma could transform his personality, leading him to become a killer with a vendetta. He might start by targeting the ones directly responsible and then expand his scope as his thirst for vengeance grows.
Well, perhaps Percy discovers some ancient power within himself that gradually transforms him into a god. He might have to face a series of trials to fully ascend, like battling powerful monsters or making difficult moral choices.
Maybe Percy discovers a hidden garden and becomes obsessed with it. He starts to learn about different plants, takes care of them, and the garden becomes his special place.
Well, if Percy Jackson were to become an Avenger in fanfiction, there would be some interesting dynamics. For one, his loyalty to his demigod friends might conflict with the Avengers' way of doing things at times. But his ability to think on his feet, which he developed from all his quests, would help him adapt quickly. And his relationship with the other Avengers, like maybe a friendly rivalry with Thor over who has better control over elemental powers, could be a great plot point.
Maybe Percy has been through a great betrayal, like his closest friend turned on him for power. So he starts to close off his emotions to avoid being hurt again.
