Who knows! It might introduce some long-lost relatives or uncover hidden secrets. Maybe there'll be a huge battle that changes everything.
Hard to say for sure. Maybe there'll be unexpected alliances or powerful enemies emerging. Or perhaps the story will focus on character development and their internal struggles.
He could return with a whole new set of allies. During the war, he might have met other powerful mages who decided to follow him back to Fairy Tail. These new allies could bring different types of magic and skills to the guild. Also, Natsu might come back with a different perspective on life. The horrors of war could make him more determined to protect peace in the world and in his guild, leading him to take on a more leadership - like role in Fairy Tail.
He might also have an emotional reaction. Spiderman is a very empathetic character. If the fanfiction shows some really tragic events during the Infinity War, he could be deeply affected. This could lead to him being more determined to prevent such tragedies from happening in his reality.
Well, there could be unexpected plot twists. Maybe one of them will have to face a personal challenge that tests their relationship during the lockdown.
Well, in a fanfiction scenario where Tony has the gauntlet in Infinity War, he might try to use it to defeat Thanos right away. Maybe he figures out how to control it quickly and unleashes a powerful blast that could turn the tide of the battle.
Well, perhaps Ash comes back with new skills and a sense of purpose. He might be determined to protect Serena even more than before. In the fanfiction, he could use his war - learned strategies to deal with any threats that come their way. And their relationship could evolve into a deeper, more mature love as they face new challenges together.
Perhaps Loki would find a way to bring back some of the fallen. With his magic, which is often underestimated, he could search for ways to reverse the effects of the Infinity Stones. This would be a huge task, but if he managed to do it, it would change the course of the entire universe. He might start with trying to bring back his brother Thor, as their relationship has always been complex yet deep.
Well, one possibility is that Ash has changed a great deal due to the war. Maybe he has new skills or a more hardened personality. He could struggle to fit back into his old life with Serana. For example, he might be haunted by the memories of the war and find it difficult to be as carefree as he once was with her.
Well, there could be a sequel. Maybe new characters will be introduced, or the existing ones will face new challenges. For example, if it's a story about a hero, he might encounter an even stronger villain in the next part.
Maybe there would be a sudden, unexplained noise. Like a loud creaking from an old, abandoned house. The main character might then start to feel as if they're being watched, but when they look around, there's nothing there. Then, they notice a single footprint in the mud that wasn't there before.
Well, they might initially be cautious of each other. Talion, with his undead state and ranger skills from Middle - earth's darker regions, and Aragorn, the rightful king and a great ranger in his own right. They could exchange stories of their battles against the forces of evil. Maybe Talion would share his experiences with the Ringwraiths, and Aragorn could tell of his adventures fighting Sauron's minions. They could also compare their fighting styles and learn from each other, which would make for an interesting dynamic in the fanfiction.
