Well, one of the most memorable scenes might be the epic battles. The way the heroes come together to fight against the powerful villains is really exciting. Also, the character interactions are great. For example, when characters who haven't interacted much before have to team up, it creates interesting dynamics.
The plot could be different. There could be new sub - plots or twists that the fanfic writer has added. Maybe in the fanfic, there's a different villain's plan or a different way the Infinity Stones are used. Also, the relationships between characters could be altered. Some friendships or rivalries might be stronger or weaker in the fanfic than in the movie.
One possibility is that the students of Midtown High are completely shocked by the events in Infinity War. They might gather in groups to discuss and debate about their favorite characters' fates. For example, Peter Parker's friends Ned and MJ could be really worried about him. They might try to analyze every scene he was in, wondering if there were any signs that could have predicted his situation. Maybe they would even come up with their own theories about how things could have been different if certain events had played out otherwise.
One of the most interesting plots could be the characters having different alliances. For example, in some fanfictions, Loki might team up with the Avengers against Thanos in a way that was not shown in the movie. Another plot could be about the aftermath for the citizens of Midtown during the events of Infinity War. They might have their own stories of survival and heroism that are not part of the main movie narrative.
Some students might be in awe of the power of the Avengers and the other heroes. They could start idolizing them even more. They might try to mimic the heroes' actions in their own small ways, like being more courageous in standing up to bullies at school. And for those who are more tech - savvy, they might start thinking about how they could use technology to help in a similar way to Iron Man or Shuri.
Fanfictions can change how we view the relationships between characters too. Consider a fanfiction where Steve Rogers and Bucky Barnes have a different kind of reunion during Infinity War. This can affect how we see their bond in the movie. Also, for characters like Scarlet Witch, fanfictions can explore her powers in new ways. If she uses her powers to protect Midtown in a fanfiction, it gives a new dimension to her character as a protector rather than just a powerful Avenger.
Well, a common plot is that the students of Midtown High start to debate about the moral issues shown in the Civil War fanfiction. Some might side with one group's stance on registration, while others oppose it, leading to interesting character development and relationships. Also, there could be a plot where a Midtown High student discovers a way to enter the world of the fanfiction and has to navigate the complex politics there.
There might be a fanfiction where the Asgardians are actually brought back to watch Infinity War in a sort of time - loop scenario. They are trying to figure out how to change the outcome, especially since they have knowledge of the power of the Stones. This could lead to some really creative plot twists as they interact with the Avengers in the movie.
If Naruto were to watch Infinity War fanfiction, it would be a wild mix of two very different universes. Naruto is all about honor, friendship, and the pursuit of being a great Hokage. Infinity War has its own themes of sacrifice and the fight against ultimate evil. Naruto might be shocked by the large - scale destruction in the fanfiction. He could also be inspired by the way the Avengers come together from different backgrounds. He might even start imagining if he could form a similar kind of coalition in the ninja world to deal with threats that are too big for one village to handle.
In this type of fanfic, the Infinity Stones could have a very different effect in the Harry Potter universe. For example, the Time Stone could be used to reverse dark spells or resurrect fallen wizards. However, the Stones' power might also be limited by the magic rules of the wizarding world. The fanfic could delve into how the characters from both universes adapt to the presence of the Stones and how they use or misuse their power.
