What could be the plot of a fanfic where The Avengers kidnap Harry?

Well, perhaps in this fanfic, the Avengers misunderstand Spiderman's actions. Maybe they think he's been compromised by some powerful enemy force, so they decide to kidnap him to figure out what's really going on. They could take him to a secret location, like an abandoned SHIELD base. Then Spiderman has to convince them that he's on their side while also dealing with his own feelings of betrayal.

In a fanfiction scenario where the Avengers kidnap Spider - Man, it could be because of a prophecy. The Avengers might believe that Spider - Man will cause great harm in the future according to some ancient prophecy. So, they take him against his will to a secret location. However, Spider - Man manages to convince some of the younger Avengers, like Peter Parker's friends among them, that he's not a threat.

Well, perhaps Harry uses his magic skills like the Patronus charm to fend off some dark force that is attacking the Avengers. He could also use his knowledge of potions to heal any injured Avengers.

It could be Mysterio. He's a master of illusions. He might trick the Avengers into believing that Spiderman is a danger, using his illusions to make it seem like Spiderman is doing bad things. So the Avengers, thinking they're doing the right thing, kidnap Spiderman.

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.

Harry could fit in by using his magic for reconnaissance. His invisibility cloak would be great for spying on enemies unnoticed. The Avengers could use this to their advantage when planning attacks.

One plot could be that the cat avengers are split into two groups due to a misunderstanding. One group believes that the other is working with a group of rats who are stealing cat food. As they fight among themselves, the real villains, a gang of raccoons, start to take over the town. Eventually, the cats realize their mistake and reunite. They then use their combined powers, like the flying cat to scout the raccoons' movements, the strong cat to fight them directly, and the invisible cat to launch surprise attacks, to drive the raccoons out of the town.

The plot might involve a new villain who hacks into their chatroom. So, the Avengers have to figure out how to stop this digital threat while also communicating within the chatroom to coordinate their efforts. They could be discussing their individual strengths and how to use them against this new enemy. For example, Captain America could be leading the conversation on strategy, while Black Widow provides intel she's gathered. Hulk might be there just being Hulk, with the others trying to keep him calm and on track. And all of this happening in the unique setting of a chatroom, which adds a modern and interesting twist to the typical Avengers story.

Well, it could be about the Avengers having a peaceful slumber in their tower. Maybe they're all having dreams related to their past battles or future threats. For example, Iron Man might dream about improving his suit in his sleep, while Captain America dreams of the old days in Brooklyn.

Well, perhaps the Avengers could be at a party and accidentally get drunk on some alien beverage. Then they start acting out of character, like Thor trying to dance like a pop star and Iron Man making really silly gadgets just for fun.
