At first, Spiderman would be in shock. But then he'd start to analyze the situation. He'd realize that Deadpool is not going to harm him in a traditional sense. So he might play along for a while, waiting for the right moment to turn the tables. He could pretend to be interested in Deadpool's plan, all the while formulating his own escape strategy and thinking about how to get Deadpool to see the error of his ways.
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.'
Another possibility is that Deadpool kidnaps Spiderman because he's bored. He sees Spiderman as this straight - laced hero and figures that by kidnapping him, he can mess with Spiderman's life a bit. He could take Spiderman to some really strange places, like a dimension full of dancing hot dogs (because it's Deadpool, anything is possible) and Spiderman has to find a way to escape while also dealing with Deadpool's crazy antics.
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.
Well, in some versions he might use his webs to create a distraction and then slip away while Doc Ock is focused on that. Maybe he'll find a weak point in Doc Ock's mechanical arms and disable them to make his escape.
Their relationship could start out as rivals. Spiderman, with his more traditional heroic values, might be put off by Fem Deadpool's wild and unpredictable nature. But as they face common enemies, they would gradually develop respect for each other's fighting abilities, which could turn into a friendship.
Deadpool could use his sense of humor to break through Spiderman's dark thoughts. He might crack jokes that at first annoy Spiderman but eventually start to make him see things differently. As time goes on, Spiderman could come to appreciate Deadpool's unique way of looking at life, and they could become really close friends. They could also have deep conversations in between their crazy adventures. For example, while sitting on a rooftop after a fight, Deadpool might share some of his own experiences with pain and how he copes, which makes Spiderman feel less alone.
Iron Man might be protective. He'd probably see Spiderman as a young protege and would want to keep his identity safe using all his tech resources.
One possible scenario in this fanfiction could be that Loki disguises himself and lures Spiderman into a trap. He then transports him to a different realm where Spiderman is completely out of his element. Spiderman would have to rely on his wits and basic powers to try and escape Loki's clutches.
The ages of Spiderman and Deadpool in the comics aren't fixed. Spiderman is usually around his 20s, but Deadpool's age is more flexible. It can be influenced by the writers' decisions and the demands of the plot. So, it's not straightforward to give an exact number for either of them.
Venom could also be a main antagonist. Imagine if he somehow got enhanced and became even more powerful. He could be causing chaos in the city, and both Spiderman and Deadpool would have to figure out a way to defeat him. Deadpool's lack of fear and Spiderman's knowledge of Venom could be key factors in their fight.
If Loki kidnaps Spiderman in fanfiction, it would be a very interesting plot. Loki is a powerful and cunning character, while Spiderman is a beloved hero. Loki might underestimate Spiderman's resourcefulness though. Spiderman could use his spider - sense to find weaknesses in Loki's plans.
