Perhaps the plot focuses on the personal growth of each character since their last encounter. They might have new powers or skills, and the reunion is a chance to show off and also reconnect on a deeper level. For example, Iron Man's protege could have developed a new type of armor that the others are in awe of. And they also deal with the emotional baggage of their previous adventures together, like the loss of some comrades.
The fanfiction could center around a celebration that turns into a mission. They are all gathered for a reunion party, but then an unexpected attack occurs. This forces them to quickly fall back into their superhero roles and work together again. They may struggle at first because they've been apart for a while, but then they find their rhythm and defeat the new villains.
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.
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.
It could involve different timelines of the Avengers coming together. Maybe the Avengers from the original team meet their counterparts from an alternate universe where things like Tony Stark never became Iron Man in a different way. They have to team up to fight a common enemy that threatens all the universes.
The plot could involve a time - travel aspect. The new Avengers accidentally get sent back in time and interact with the original Avengers. This would create some interesting scenarios where they learn from each other. They could also bring back some knowledge or technology from the past to help them in their fight against a future threat that has been plaguing their time.
One possible plot could be the young Avengers traveling back in time to prevent a major disaster that led to the downfall of the original Avengers. They might have to face challenges like not changing the timeline too much while still achieving their goal. For example, they could go back to a time when a powerful villain first got their hands on a dangerous weapon. They'd need to outwit this villain in the past without causing new problems for the future.
In the 'The Next Avengers: Heroes of Tomorrow Fanfiction', it could also be about the relationships between the new Avengers. They come from different backgrounds and have different personalities. There could be some internal conflicts at first. But as they face challenges together, they learn to work as a team. Maybe there is a love story between two of the young heroes that develops as they fight side by side, which also adds an interesting element to the overall story.
One possible plot twist could be that the time travel causes unexpected changes to the Avengers' powers. For example, Iron Man might find his suit malfunctioning in a new way due to the altered timeline. Another could be that the villains they face in the past are actually aware of their time - traveling presence and are setting traps. Also, a character from the future could turn out to be a hidden villain who is using the time travel to change history for their own evil gains.
Well, it could be about Azari using time travel to prevent a great disaster in the Avengers' future. Maybe he goes back in time to warn the original Avengers about a threat they didn't see coming, like an even more powerful version of Thanos. He might have to deal with the challenges of changing the past and the potential consequences it could have on the future.
Captain America's protege would be an interesting choice. He has big shoes to fill, and seeing how he has developed in the absence of Captain America would be engaging. He might struggle with living up to the legacy, but at the same time, he could bring his own unique style and leadership to the group during the reunion. His relationships with the other young Avengers, especially those who knew Captain America well, could be a major part of the story.
Perhaps in the fanfiction, they reunite while on individual vacations in a small, idyllic town. At first, it's awkward, but then they start reminiscing about their old times. They decide to have a private jam session, just like the old days, which leads to discussions about a possible comeback.
One possibility is that it could bring a lot of drama. Her pregnancy might cause tension among the former Glee club members. Some might be excited for her, while others could be worried about how it will affect their reunion. Maybe there will be conflicts over who will support her during this time.
