Well, it can show different versions through the eyes of the fan. For example, a fanfiction could have a version of Spiderman who has a different suit, like one made entirely of nanotechnology that can transform into different shapes. The encounter between the real Spiderman and this fan - created version could explore how different looks can affect the perception of the hero.
Spiderman's reaction could be complex. He might start by being intrigued by the idea of fanfiction in general. As he reads the 'Spiderman Homecoming' fanfiction, he might be impressed by the attention to detail some fans put in. He may also be a bit embarrassed if there are overly sappy or romantic interpretations of his character. At the same time, if there are fanfictions that show him in a negative light, he might feel the need to defend himself, but overall, he'd probably see it as an interesting part of his popularity and the fans' creativity.
Spiderman would probably be really confused at first. I mean, Deadpool is not your typical villain. He'd likely try to talk Deadpool out of whatever crazy plan he has. He'd be using his quick wit and trying to reason with Deadpool, saying things like 'This is not the right way to do things, Deadpool.'
Perhaps in the fanfiction, a young Spiderman fan who has a special power he doesn't know about yet meets the real Spiderman. They both have to figure out how to use the fan's power to stop a group of criminals who are stealing tech from Oscorp. This would involve a lot of character development for the fan character as he discovers his abilities with Spiderman's guidance.
One idea could be that Spiderman and Mockingbird team up to take on a new supervillain in the city. Maybe this villain has the ability to control technology and is causing chaos. Spiderman's agility and Mockingbird's combat skills would make for an interesting dynamic in the fight.
Fanfiction can also delve into the backstories of these characters. Maybe Silk has a secret past that only Spiderman can help her with. Or perhaps Spiderman discovers something new about his own powers through his interactions with Silk. This creates a lot of interesting plot possibilities.
In general, watching non - commercial fanfiction - based content like fan - made videos or animations is often in a legal gray area. If it's purely for non - profit, transformative, and not causing any harm to the original brand, it may be considered okay. But if it uses copyrighted material in a way that violates the rights of the original creators, it could be illegal.
Another idea is a time - travel fanfiction. Spider - Man could be sent back in time to when his Uncle Ben was still alive. He would have the chance to prevent his uncle's death, but he'd also have to deal with the consequences of changing the timeline, like how it might affect his own development as a hero.
In this fanfiction, Aay could be a long - lost relative of one of Spiderman's friends or enemies. Through a series of events, Spiderman discovers this connection. Aay has some unique abilities or knowledge that is related to lemons. This connection between Aay and Spiderman's world brings new challenges and adventures as they try to figure out how to use Aay's lemon - related stuff to their advantage in the fight against evil.
It could be Doctor Octopus. He might have some new, more dangerous tentacle - like devices. He decides to target both Spiderman and female Spiderman because he views them as obstacles to his scientific experiments and his desire for power. He kidnaps some innocent people to lure them into his traps and tries to defeat them in a fight.
