Fanfictions sometimes create scenarios where Spider - Man from 'Homecoming' has to prove himself to the established Avengers. His youth and inexperience contrast with the more seasoned heroes. This can lead to interesting character development arcs, such as him learning from the Avengers' combat strategies and they in turn learning from his unique approach to fighting crime on a smaller scale.
Maybe there is a common enemy that exists in both their worlds. This enemy could be a powerful being that has the ability to travel between dimensions. Spider Man discovers that there are strange disappearances in New York that seem to be related to something otherworldly. Meanwhile, Proxima is on the hunt for a being that has caused chaos in her world. Through a series of events, they both realize that they are after the same foe. This would force them to put aside their differences and combine their powers to take on this mutual enemy.
He could be a new recruit. The Avengers are always looking for new talent, and Spider - Man's abilities would be a great addition. He could start off as a bit of an outsider, trying to fit in with the more experienced heroes.
In a fanfiction, Spider - Man could get lost in an alternate dimension during a mission. The Avengers then have to find a way to bring him back. While in the alternate dimension, Spider - Man meets different versions of the Avengers and has to fight his way through various challenges to return home.
Well, Tony Stark might be amused and a bit proud. He'd probably see the fanfiction as a testament to how much Spider - Man has grown under his mentorship. Steve Rogers might be a bit confused at first, but then he'd appreciate the creativity and the way it shows the bond within the team. Thor would likely find it all very entertaining and might even want to hear more stories about Spider - Man's adventures in this fictional take.
If we consider the cultural differences between the two worlds, it would add an interesting layer to the fanfiction. The Avengers are from a modern, Western - influenced world where science and reason are highly valued. Magnus Chase's world is steeped in Norse mythology and ancient traditions. When their worlds collide, there could be misunderstandings at first. But as they get to know each other, they could learn from one another. The Avengers could learn about the power of magic and ancient wisdom from Magnus, and Magnus could learn about the power of teamwork and modern technology from the Avengers.
Culturally, there would be a huge clash. The Avengers are from different parts of Earth, with different values and beliefs. Crowley, on the other hand, comes from a world of demons and magic. His actions and motives would be completely foreign to the Avengers. For example, Crowley's casual attitude towards death and destruction might horrify the Avengers, who are dedicated to protecting life.
One idea could be a fanfiction where Spider - Man has to team up with the Avengers to stop a new villain that is specifically targeting his neighborhood in Queens. This would combine the street - level heroics of Spider - Man with the big - scale action of the Avengers.
One popular trope is the mentorship. Since Spider - Man has a connection with Tony Stark in the movie, fanfictions often expand on this. Another is the 'fish out of water' trope where Spider - Man is out of his comfort zone when dealing with the Avengers' big - scale operations.
Tony's confident and sarcastic personality would make him either praise or mock the fanfiction playfully. Steve's more serious and traditional nature would lead him to look for positive moral lessons in it. Thor's boisterous and fun - loving side would make him enjoy it wholeheartedly.
Their universes can collide in fanfiction through interdimensional portals. Maybe a scientist in the Marvel universe accidentally creates a portal that links New York (Spider - Man's territory) and Wakanda (Shuri's home).
