Deadpool could also be protective. If Spider - Man is a teen, he might see himself as a sort of protector. He could say something like 'Hey, little spider, I got your back since you're just a youngster in this crazy hero business.' He'd probably crack some jokes about it too, like 'You're so young, your suit is probably still in training wheels!'
On the other hand, if Spider - Man is older than Deadpool thought, he might be impressed. He could say 'Well, well, look at you, not as green as I thought.' And then start to treat him more as an equal in their adventures together, rather than as someone he needs to look out for all the time.
Well, in most of the common fanfictions, Spider - Man is often depicted as a teenager, usually around 15 - 17 years old. But it really depends on the specific plot and the writer's interpretation in that particular fanfiction.
Charlie may initially be confused. Fanfiction isn't something he might be very familiar with. But once he understands what it is about Harry and Ginny, he might just shrug it off. He's got his own life with dragons and such, so he might not really care all that much as long as it doesn't cause any real - world problems for his sister and Harry. However, if it spreads some false or unflattering rumors in the wizarding community, he might get a bit annoyed.
He might be quite shocked at first. After all, Wolfstar involves his dad's best friend Sirius and his other dad figure Lupin. It's a rather strange concept for him to think about them in a romantic way as he knew them in a different context.
His reaction could be one of confusion. Fanfiction isn't really part of the pure - blood wizarding world he's used to. So seeing Harry doing something so different like cutting fanfiction would leave him scratching his head, not really understanding what Harry is up to or why he's doing it.
In some fanfictions, Snape might be secretly sympathetic. He may see the scars as a reminder of all Harry has been through, which could soften his usually harsh attitude towards Harry, at least for a moment.
Naruto might be super excited. He loves making new friends, and a toddler would be like a new little friend to him. He'd probably start showing off his ninja moves to make the toddler laugh.
Some Avengers might be surprised. Tony Stark, for instance, might be like 'Kid, you're younger than I thought!' and then start to adjust how he mentors Spider - Man. He could become more cautious about the risks he lets Spider - Man take.
Yes, there are many great 'Deadpool and Spider - Man' fanfictions. Some focus on their unlikely friendship, like those where they team up to fight a common enemy in a really comical way. They play off each other's personalities really well in these stories, with Deadpool's craziness and Spider - Man's sense of responsibility creating an interesting dynamic.
He would probably be very displeased. Snape has always been strict and traditional, and fanfiction about the DA, which was an unauthorized student group in his eyes, would seem like a frivolous and inappropriate thing to him.
Well, Percy has seen a lot in his adventures. At first, he might be a bit taken aback because fanfiction is a whole new world compared to his real experiences. However, as he realizes that it's just fans exploring different scenarios with the characters, he could become rather indifferent. He might even start to see the value in it, as it shows how much the fans care about the overall story and its characters. He might think it's a little strange that people are so interested in writing about Nico and Will's relationship, but he'd respect the creativity of the fans.
