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.

Maybe Cozmo gets lost in a different dimension. Tails, using his intelligence and gadgets, manages to find a way to that dimension. When they see each other again, Cozmo is a bit scared but Tails comforts him. They then have to find a way back home. On their journey back, they encounter strange creatures and have to use their combined skills to overcome obstacles. Their friendship grows stronger during this reunion adventure.

It could be about the young Avengers reuniting to face a new threat that is related to their past enemies. Maybe a remnant of Hydra has found a way to use old technology against them.

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.

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 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.

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.

A possible plot twist is that a mysterious letter arrives at the reunion. It contains secrets about the family's past that some members were trying to hide. This could lead to arguments and revelations. Also, a sudden change in the weather could be a twist. A storm hits during the outdoor reunion, and they all have to take shelter in an old, supposedly haunted family building. There, they discover hidden passages and more family secrets. And what if a family member shows up with a completely different personality due to an accident, adding confusion and drama to the reunion?

Well, it could be that Edward returns to Forks after a long time away. Maybe he realizes he can't live without Bella. He shows up at her house, and they have a very emotional reunion. Bella is initially shocked but then overjoyed.
