One interesting storyline could be Spider - Man teaming up with the Avengers to fight a new super - villain that's a combination of different powers they've faced before. For example, a villain with the strength of the Hulk and the mind - control abilities of Loki.
The Avengers would be very concerned. Captain America would immediately take charge of the situation, trying to keep everyone calm while they assess Spider - Man's injuries. Iron Man would start scanning for the best way to treat him, using his high - tech equipment. Thor might offer some of his Asgardian knowledge of healing, if there was any. Black Widow and Hawkeye would be on guard, making sure there were no further threats while the team focused on Spider - Man.
In many Avengers fanfics, Spider - Man's sacrifice can be a very powerful plot point. It often shows his selfless nature. He might sacrifice himself to save his fellow Avengers or the world from a great threat. This kind of sacrifice also adds depth to his character as it shows his growth from a young hero to one who is willing to give everything for the greater good.
Iron Man is a great character to pair with Spider - Man. Tony Stark can act as a mentor to Peter Parker, providing him with new and advanced tech for his suit. They also have a fun dynamic, with Stark's sarcasm and Spider - Man's youthful exuberance.
Spider - Man could use his agility and web - slinging skills to escape. He could swing between buildings, making it difficult for the Avengers to follow him. His small size compared to some of the Avengers also gives him an advantage in hiding in tight spaces.
Spider-Man has definitely been in the Avengers in the comics. His presence has added a fresh dynamic and his powers and wit have been valuable assets to the group.
The Avengers might have a range of reactions. Tony Stark could be amused and might make some sarcastic comments about the plot or the way Spider - Man is portrayed. Steve Rogers might be a bit more traditional in his view, perhaps finding it interesting how the fanfic explores different aspects of Spider - Man's character. Thor could be a bit confused at first but then find the whole idea of a fan - created story quite fascinating.
In many Avengers - related fanfics, Spider - Man's identity can be a major plot point. Some fanfics might explore the idea of his identity being revealed within the Avengers team earlier than in the official comics or movies. This could lead to various reactions from the other Avengers members. For example, Tony Stark might take on a protective role, while Captain America could be more concerned about the implications for the team's secrecy.
Well, Tony Stark might be amused and start making sarcastic comments about the plot or the characterizations in the fanfic. He'd probably find some of the more out - there ideas in the fanfic either really cool or just plain ridiculous.
