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.
Captain America would be really interesting. His moral compass and leadership skills in a time - travel scenario would be fascinating. He has to deal with the changes in the past that the time travel causes, and also make sure the other Avengers stay on the right path. He might struggle with seeing his old world again and having to make choices that could change it further.
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.
Definitely Torunn. She has a great backstory being Thor's daughter, and her powers are really interesting. You can explore her journey of living up to her father's name and forging her own path as a hero.
Loki could be a great focus in a fanfiction involving both. He has a history with the Avengers, but his wily and unpredictable nature could lead to some interesting interactions with the Agents of Shield. He could be playing his own game, pretending to help both groups while actually having his own agenda. It would be fun to write about how the Agents and the Avengers try to figure out his true motives and keep him in check.
One interesting concept could be the introduction of new, younger heroes in the Next Avengers era. They might have different powers and personalities compared to the original Avengers. For example, they could have powers that are a combination of modern technology and magic, which would create unique storylines.
Thor could also be a great character to focus on. He has his Asgardian powers and a different cultural background compared to the others. In a fanfiction with Doctor Strange and the Avengers, he could be the one who has the most trouble understanding Doctor Strange's magic at first. His reactions to the strange magical situations and how he tries to incorporate his own strength and honor into the mix could create some really engaging storylines. Also, his relationship with other Avengers and how it changes with the addition of Doctor Strange's presence could be explored.
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.
Angela would be a great character to focus on. She was such a strong and independent character. In a reunion, we could see how she has balanced her career and personal life. Maybe she has traveled the world and has amazing stories to share, and how her relationship with Shawn has either deepened or changed in unexpected ways.
I think Spider - Man himself would be the most interesting. He's a young and relatively inexperienced hero compared to the Avengers. His different perspective and his unique powers like climbing walls and the spider - sense would add a lot of flavor to the story. He could also bring in a sense of humor and a bit of naivete that would contrast with the more jaded Avengers.
I think Daisy Johnson would be really interesting. She has her unique powers and a complex backstory from her time in SHIELD. In a crossover, she could interact with the likes of Thor. Maybe she could learn some new ways to control her powers from him, as he has experience with his own godly powers. And she could also show the Avengers her skills in combat and stealth that she learned in SHIELD. It would be fascinating to see how she holds her own among the super - powerful Avengers.
