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.
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, 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.
It could be Captain America. He has a strong sense of justice and kindness. So, if he found a dog, he would surely take it under his wing and protect it. Maybe he'd even train the dog to be a mascot for the Avengers.
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.
If Loki becomes an Avenger in fanfiction, it would be a wild ride. He'd bring his complex personality to the team. His relationship with Thor would also be an interesting aspect. They could have brotherly moments within the team dynamic. Loki might also start to develop real friendships with the other Avengers, which would be a big change for him.
It could be really cool. Percy might use his water - controlling powers in new and creative ways with the Avengers. For example, he could help Thor with his lightning by creating water - based conductors.
In some fanfictions, the 7th Avenger could be a time - traveler from the future. This person has come back to prevent a major disaster that the Avengers couldn't handle without their help. They know all about the future events and use this knowledge to guide the team, but also have to be careful not to change the timeline too much.
Well, he'd probably bring his magic skills to the Avengers. He could use spells like Expelliarmus to disarm villains quickly. His broomstick flying skills might also come in handy for getting around in a hurry or for some unique battle maneuvers.
He would likely become more cynical. In the normal story, Shirou is fairly idealistic. But as an Avenger, he'd see the darker side of things more often. For instance, he might not trust people as easily as he used to. He would always be on the lookout for hidden motives.
It could be Iron Man. Since Harley is interested in technology, he'd be really drawn to Iron Man's high - tech suits and gadgets. He'd probably love to see how they work up close and maybe even get a chance to tinker with them a bit.
