What could be the plot of a '1d reunion fanfiction'?

Perhaps in the fanfiction, the Avengers reunite for a more personal reason. One of their own, say Tony Stark (even if he's no longer alive in the main timeline), has somehow sent a distress signal from an alternate reality. They come together, not just to rescue him but also to explore this new and strange reality where things are different. They might meet alternate versions of themselves and have to team up with these versions to solve a problem that is affecting both realities.

In a 'Percy and Sally Reunion' fanfiction, Percy could return after being presumed dead. Sally has been mourning him all this time. His sudden appearance shocks and delights her. They hug tightly and don't let go for a long time. Percy then shows Sally his new powers or skills he's acquired during his time away. They also plan for a future where Percy can stay closer to home and help protect it, and Sally is just happy to have her son back in her life.

The plot could start with Luffy getting a strange feeling that he needs to go home. His brothers, Ace and Sabo, also have the same feeling. They all start their journey towards their family home. Along the way, they face some challenges, like bad weather and pirates. But they persevere. When they finally meet, there are hugs and lots of catching up. Maybe they find out some long - lost family secrets during their reunion.

One possible plot could be a grand adventure where they team up to take on a powerful enemy that threatens the safety of their hometown. They could use their combined skills and the strong bond they share to overcome challenges.

It could be Harry Styles. Since he has had a very successful solo career, he might be the one who initiates the reunion, using his influence and popularity to bring the boys back together.

The plot could start with a long - standing feud between them finally boiling over. Maybe Murdoc has been stealing 2D's things or messing with his music again. 2D gets fed up and decides to stand up to Murdoc. They start with a verbal argument that quickly turns physical. 2D tries to land some punches, while Murdoc dodges and tries to trip 2D up. As the fight goes on, they both start to realize how much they actually need each other in the band, but their pride won't let them stop fighting right away.

It could be a very emotional reunion. Thor might be initially angry at Loki for all his past misdeeds but then quickly soften as he realizes how much he has missed his brother. Loki, on the other hand, might be a bit guarded at first, still not fully trusting Thor's reaction. But eventually, they would embrace and start to rebuild their relationship.

Well, in the fanfiction, their reunion could lead to them teaming up. Maybe they decide to take on a powerful enemy together. They'd combine their skills, with Ace's fire powers and Sabo's fighting abilities, and create a formidable force. They'd also probably have some deep conversations about their past and how much they missed each other.

Well, in a fanfiction, their reunion could be in a completely new region. Ash has been invited to a special Pokémon event there and Serena, having heard about it, travels all the way just to see him again. When they reunite, Serena has become an even more confident and skilled Pokémon coordinator. Ash is so proud of her growth, and they decide to team up for a new adventure in this unfamiliar region.

They might have a very emotional moment. Sasuke could finally open up about his long journey and all the things he has been through. Sakura, on the other hand, would be so happy to see him again and might just break down in tears. They could share a long hug, a hug that they both have been waiting for for so long.
