Well, it could be about Ant Man bringing his unique shrinking abilities to help the Avengers in a new, unexpected threat. Maybe he shrinks down to infiltrate an enemy's base that the Avengers can't access otherwise.
One possible plot is that the Avengers are facing a foe who can manipulate time and space. Ant Man, with his experience in the Quantum Realm, could be the key to understanding this new threat. He could share his insights about the strange physics in the Quantum Realm with the Avengers, like how time and space work differently there. Together, they develop a strategy to defeat the enemy by using Ant Man's ability to enter the Quantum Realm and disrupt the villain's power source.
In the fanfiction, perhaps Ant Man accidentally stumbles upon an Avengers' secret mission while on his own adventure. He then teams up with them, using his knowledge of the microscopic world to solve a mystery that involves some sort of nano - tech based villain. His ability to communicate with ants might also play a crucial role in gathering intelligence for the Avengers.
Perhaps in the fanfic, Ant Man accidentally shrinks himself too much and gets lost in Spider Man's suit. Spider Man then has to figure out how to get him out without harming him. Meanwhile, they discover that there's a mini - world inside the suit with its own set of problems, like tiny villains causing chaos, and they have to deal with that together.
Obviously, Ant Man himself would be one of the main characters. And then, of course, the core Avengers like Iron Man, Captain America, Thor, Hulk, and Black Widow are likely to be there too. They are the mainstay of the Avengers and would be natural counterparts for Ant Man to interact with.
One possible plot could be that Naruto discovers a mysterious technology similar to Ant - Man's suit. He then uses it to shrink himself and infiltrate hidden enemy bases in the Naruto universe. He could use his ninja skills in combination with the shrinking ability to outwit his foes.
One possible plot could be that Sonic gets accidentally transported to the Marvel universe where the Avengers are based. At first, there's some confusion and mistrust. But as they face a common enemy, like a powerful interdimensional villain who wants to conquer both Sonic's world and the Avengers' world. Sonic and the Avengers have to combine their unique abilities. Sonic's super speed, agility and his friends' skills along with the Avengers' superpowers, high - tech weapons and combat experience. They learn from each other during the fight, and in the end, they become friends and Sonic might even get a chance to visit the Avengers again in future adventures.
In the fanfiction, Sherlock could be investigating a series of disappearances that are somehow related to the Avengers. Maybe the disappearances are part of a plan by a new villain who wants to use the Avengers' powers for his own evil purposes. Sherlock would use his powers of observation to find clues that the Avengers missed. He could also get into some interesting debates with Captain America about justice and the law, as Sherlock has his own unique view on these matters. The story could end with them working together to rescue the captives and defeat the villain.
The plot could involve Superman arriving in the Avengers' world during a time when they are divided. His presence could be the catalyst that brings them back together. Superman's moral code and unwavering belief in doing good might inspire some of the more conflicted Avengers. They could then join forces to face a common enemy, like an alien race that is trying to invade Earth. Superman would bring his super - speed, heat vision and flight to the table, while the Avengers would contribute their own unique powers and technology. It would be an epic crossover full of action and heroic moments.
The new dynamic would surely involve his sense of humor. Ant Man has a very relatable and down - to - earth humor. When he joins the Avengers, he could lighten the mood during tense situations. For instance, in the middle of a serious battle strategy meeting, he might crack a joke about how his suit's technology is more reliable than Stark's latest gadget. His different background, coming from a more ordinary life before becoming a superhero, could also add a fresh perspective to the team's decision - making processes.
It depends on each Avenger's taste. Some like Tony Stark might enjoy it for its creativity, while Steve Rogers may not be too fond of it if it doesn't align with his idea of the proper story. So, there's no one - size - fits - all answer.
They might find it really strange or interesting. Some Avengers could be amused by the creative interpretations of Ant - Man's character and adventures in the fanfiction. For example, Tony Stark might make sarcastic comments about how the fanfiction writer portrayed Ant - Man's technology compared to his own. And Thor might be completely baffled by some of the more modern and out - there concepts in the fanfiction.
In fanfiction, Spider - Man could show off his acrobatic skills to the Avengers. Maybe he'd do some amazing web - slinging stunts that would leave Iron Man impressed and Captain America in awe.
