Often, it might show them trying to find their own identities again. Tony could focus more on his Stark Industries projects, pouring all his energy into creating new technology. Steve, on the other hand, might go back to a more solitary life, perhaps traveling around to help small communities in need.
Some fanfictions develop the story by having them eventually reconcile as friends. They realize that despite the divorce, they still care about each other and the world they are trying to protect. They start to work together again on a more professional level, putting aside their personal differences.
One possible reason could be differences in their superhero duties. Maybe their approaches to saving the world clashed so much that it put a strain on their relationship. For example, Tony might be more into high - tech solutions while Steve prefers a more traditional, hands - on approach.
Well, it could show them trying to move on separately. James might focus on his career more and start to travel for work. Lily, on the other hand, could go back to school to study something she's always been interested in.
One possible plot reason could be ideological differences. Tony Stark is often portrayed as a tech - savvy capitalist, while Steve Rogers has more traditional values. Their views on how to protect the world, like Tony's preference for high - tech solutions and Steve's leaning towards more human - centered approaches, might drive them apart to the point of divorce in the fanfiction.
Natasha Romanoff would be disappointed. She values the unity among the Avengers and sees Tony and Steve as important pillars of that unity. She might try to mediate at first, but if the divorce is inevitable, she'd be sad to see the team's dynamic change so drastically.
The story could develop with Tony trying to reason with Steve. Tony might use his intelligence to talk Steve out of whatever his plan is. He could point out the flaws in Steve's reasoning or show him evidence that he's been misled.
At first, it might be a bit rocky. Tony, being used to his own space, might feel smothered by Steve and Bucky's over - protectiveness. But as time goes on, he'll start to see their good intentions. Steve's moral compass will inspire Tony to be a better person, and Bucky's loyalty will make Tony feel secure. Eventually, they'll become like a real family, with Tony looking up to Steve as a father figure and seeing Bucky as a cool older brother.
Another way the story can develop is that the remaining Avengers try to win Tony back. They realize their mistakes and make efforts to reconcile with him. This could involve a lot of emotional scenes and character growth for both Tony and the other Avengers.
Often, the story might follow Tony as he adjusts to his new life. He could face initial difficulties in adapting to a different work environment or routine if he gets a new job.
Often, Peter will go off on his own path. He might start to form his own team or work independently to prove himself. For example, he could start taking on smaller villains in his neighborhood to show that he doesn't need Tony's support.
Perhaps in a post - Endgame world, Tony didn't die but lost his memory. Steve takes it upon himself to help Tony regain his memories. Along the way, they re - explore their relationship, the Avengers, and all the events that led to that point. Steve shows Tony videos and tells stories, and slowly Tony starts to remember, leading to a renewal of their friendship and a new start for the Avengers.
