In this fanfic plot, Bucky's character development could be significant. His family's love and acceptance could give him the confidence to face his past traumas. He might start to heal from his inner wounds. For example, if he used to be withdrawn, he could become more social within the family. He could also learn to trust again, which is a big step for him considering his experiences. He'll be surrounded by people who care about him, and that positive environment will help shape him into a more positive and stable person.
Bucky's character will likely become more family - oriented. Once he reunites with his family, he'll realize the importance of family bonds. He might start to take on more responsibilities within the family, like helping out with family business or looking after younger family members. His values could shift towards more family - centric ones, and this will be reflected in his actions and decisions. He'll be a different Bucky, one who has found a new purpose in his family.
The fanfic could start with Bucky being hesitant to reunite with his family. He might be afraid of how they'll react to him, especially considering all that he's been through. But when he finally does reunite, it's a moment of pure joy. His family could have prepared a big celebration for him. They could cook all his favorite meals and have a party. Bucky would feel a sense of belonging again that he hasn't felt in a long time.
The author can show Bucky's growth by having him initially be hesitant or scared about the pregnancy due to his past. But then gradually, he can become more supportive and protective. For example, he could start learning about pregnancy and parenting, showing his determination to be a good father.
These fanfics usually develop the plot around Bucky's transformation. Physically, he's going through the changes of pregnancy. Emotionally, he's growing too. He might have to face his past more deeply as he thinks about becoming a father. There could be medical mysteries involved, like how his enhanced body reacts to the pregnancy in ways different from a normal human. And the plot might also explore how the baby could potentially have special abilities or be a target because of who Bucky is.
The development of their friendship can also be seen in how they interact with other characters. When they defend each other in front of the Avengers, it shows their loyalty. And they might have a moment where they work together to prank another Avenger. This kind of light - hearted activity cements their relationship. As they face more challenges together, like dealing with new villains or saving the city, their friendship grows deeper and more unbreakable.
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.
His sense of loyalty would be strongly influenced by Bucky. Bucky is known for his loyalty to Steve, and Peter would inherit this trait. He would stand by his friends and family no matter what. Also, his combat skills would progress rapidly under Bucky's tutelage. He'd become a formidable fighter at a young age, and this would boost his confidence but also make him a target for villains.
The relationship could develop into an unlikely friendship. As the reader gets to know Bucky better during the captivity, they might start to see his good side and he might start to respect the reader's strength and resilience. For example, they could start having conversations that make them realize they have more in common than they thought.
Thor would likely be enraged. He has a strong sense of justice, and seeing the torture Bucky endured would make him want to seek vengeance on those responsible. He might also see Bucky in a new light, as a survivor of great pain and suffering.
In some fanfics, it might be justified in a complex alternate universe scenario. Maybe Bucky is mind - controlled in a way that's extremely difficult to break, and he's forced to act against Steve. However, this goes against the deep - seated friendship between them in the main canon.
In many fanfictions, their relationship develops through mutual understanding. They both have a past filled with pain and secrets. For example, Bucky's history as the Winter Soldier and Natasha's past as a spy. As they face the chaos of the Civil War, they start to see that they can rely on each other. Their relationship might begin with a bit of suspicion, but as they work together to survive and figure out what's really going on, it deepens into a strong bond.
