The Avengers would likely be very solemn. They have seen death in their own world, but Harry Potter's death in a fanfiction would be a new kind of situation for them. Thor, for example, might see it as a great loss of a potential ally in the fight against dark forces, and Natasha Romanoff could be thinking about how she would feel if it was one of their own in that situation.
The Avengers might be shocked and horrified. They are used to fighting their own battles, and seeing a young wizard like Harry Potter die would be a very different kind of tragedy. They might try to figure out if there was any way they could have intervened, even though it's in a fanfiction world.
Well, some of them might be a bit critical. Sirius, for example, might be picky about how his character is portrayed. He's a proud marauder and if he saw himself being depicted in a way that didn't match his self - image, he might scoff. On the other hand, Remus might be more open - minded and enjoy seeing the different interpretations of their relationships within the wizarding world in the fanfiction.
Well, Tony Stark would probably be making snarky comments throughout. He might point out the scientific inaccuracies in the magic system if there are any. Steve Rogers would be a bit confused at first but would try to understand the story. Thor would find it all very strange compared to Asgardian tales.
The Avengers would be shocked at first. They are not used to magic and seeing Harry Potter just swoop in and stop the Snap would be quite a surprise. But then they would be extremely grateful. They might start asking Harry a million questions about his magic and how he did it.
He might be quite amused. Fanfiction often takes the original story in wild and creative directions. Harry, being used to the strange and unexpected in his own life, could find it entertaining to see how fans re - imagine his adventures, relationships, and even his character traits in new and different ways.
If the Avengers watched Avengers fanfiction, they would probably have a range of reactions. Hulk might not understand most of it and just get frustrated. Black Widow, on the other hand, would be very observant and might pick up on the different characterizations of herself. She could either like the more complex and nuanced versions or be annoyed by inaccurate portrayals. And Hawkeye might be indifferent at first, but then get drawn into the more action - packed and adventure - filled fanfictions.
He might be quite amused. He could find it interesting to see how others imagine the world he was a part of. Maybe he'd be a bit shocked at some of the wild interpretations, but overall, it would be a unique experience for him to see his story through different lenses.
They might be really confused at first. RWBY is from its own universe with its own set of stories and characters, and Markiplier fanfiction is a whole different ball game. They could find the ideas in the fanfiction really strange or even fascinating depending on what kind of fanfiction it is.
In a fanfiction where the Avengers save Harry Potter, it would be a total game - changer. The Avengers' unique skills would be very useful. Hulk could smash through any dark magic barriers. Black Widow and Hawkeye could use their stealth and marksmanship to take out threats from the shadows. And with their combined strength, they might be able to protect Harry Potter from any danger, including Voldemort's Killing Curse.
Well, some of them like Ron might be a bit skeptical at first. He's used to the 'real' Harry Potter world. But as he reads on, he might get into it. Fred and George, on the other hand, would probably look for ideas in the fanfiction that they could use for their pranks or joke products. Ginny would likely enjoy reading about different versions of Harry and her own character development in the fan - made stories.
Well, Harry Potter has been through a great deal in his own universe. When exposed to multiverse fanfiction, he could initially feel a sense of disbelief. But as he delved deeper, he'd start to see the creativity in it. He might be amused by some of the out - there ideas, like a universe where Hogwarts is a floating castle in the sky or where he's a Slytherin. He'd also perhaps feel a bit of pride in seeing how popular his story has become that people are creating these elaborate multiverse concepts around it.
