You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are tons of talented writers who create stories about Peter Parker being adorable. Just search for his name and add 'adorable' in the tags. Another option is Fanfiction.net, which also has a large collection of such stories.
They might be a bit surprised at first. Maybe Tony makes some jokes about British tea and bad teeth, but in a friendly way. Steve would probably be intrigued by Peter's different cultural background and might ask him about British history.
One great fanfiction could be 'Peter's Sick Day in the Tower'. In it, the Avengers rally around a sick Peter. They show their different ways of caring, like Tony trying to use his high - tech gadgets to diagnose Peter quickly, while Steve makes him some old - fashioned chicken soup. It's a really heartwarming story that shows the found family aspect in the Avengers universe.
His naivete. In many fanfictions, Peter is still that young, wide - eyed kid from Queens. His inexperience in some aspects of life, especially when it comes to relationships or dealing with his superhero fame, can be really endearing.
Peter would probably be really shocked at first. He might try to quickly explain who he is and that he's not a bad guy. For example, he could start blabbing about being Spider - Man and how he just wanted to meet the Avengers.
In some fanfictions, Peter uses his intelligence to outwit the bullies. For example, he might use his scientific knowledge to create small gadgets that make the bullies look foolish without using his superpowers directly. This shows his resourcefulness.
Peter is likely to be in awe. He might be a bit nervous at first, but also extremely excited. He has looked up to the Avengers for a long time, so meeting them would be like a dream come true. He would probably be stuttering a bit as he tries to introduce himself and show his respect.
One way is by getting involved in Peter's school life in a more official capacity. Maybe they could arrange for some anti - bullying seminars at the school. Natasha could also train Peter in stealth and evasion techniques so that he can avoid the bullies more easily. Thor could even offer to be Peter's bodyguard for a while, at least until the bullying situation is resolved.
Well, in this fanfiction, Peter Parker might meet the Avengers in a more casual setting. For example, he could be at a science expo where some of the Avengers are also present. Peter is there to show off his latest web - shooter design. The Avengers notice his intelligence and his unique abilities as Spider - Man. They then start a conversation with him, and from there, a relationship between Peter and the Avengers begins to form. This could lead to Peter getting involved in more Avengers - level missions and growing as a hero.
Well, in many fanfictions, the Avengers protect Peter by always having his back in battles. For example, Captain America might shield him from incoming attacks with his iconic shield. They also offer him guidance. Tony Stark could be constantly giving him advice on how to improve his suit and combat skills.
