Thor could be another character affected. As an Asgardian with a different set of values and powers, his reaction to Bucky's shocking actions would be interesting. He might view Bucky's actions from a more otherworldly perspective and his response could influence how the rest of the Avengers deal with the situation.
Well, obviously the Avengers themselves are the main characters affected. Captain America would be one of the most affected. Given their long - standing friendship, any shock from Bucky would deeply impact Steve Rogers. Tony Stark would also be greatly affected. Their relationship has been rocky in the past, and if Bucky does something unexpected, it would likely stir up new tensions or alliances between them.
Often, new characters might be introduced in the fanfiction too. But the main focus remains on Bucky and his relationship with the core Avengers. For instance, Wanda Maximoff could also play an important role. She might have some sort of connection with Bucky due to their shared experiences of being manipulated in the past. Their interactions can add depth to the story.
Maybe Bucky shocks them by suddenly showing a new power or ability that no one expected. He could have been experimented on further during his time in captivity and this new power throws the Avengers off - guard as they now have to reevaluate how to fight alongside him or against him if he were to turn.
Vision could also have an interesting interaction with Bucky. Vision is an android with a unique perspective on life and morality. He might be curious about Bucky's past as the Winter Soldier and how he is dealing with his regained humanity. Their conversations could be really thought - provoking, exploring themes like what it means to be human and how to atone for past wrongs.
One great 'Avengers Bucky Fanfiction' is 'The Winter Soldier's Redemption'. It delves deep into Bucky's struggle to regain his humanity after all he has been through. It shows his complex relationship with the other Avengers, especially Steve. Another interesting one is 'Bucky's New Beginnings' which focuses on how he tries to adapt to the modern world while still haunted by his past.
Sharon Carter could be in the fanfic. She could be the one who provides some medical or scientific insights into what's happening to Bucky. Maybe she has some knowledge of the experimental substances that might be related to Bucky's growing belly and tries to use her resources to help him.
It could also be strained. There might be some jealousy or differences in opinion on how to handle the situation. For example, one of them might want to be more involved with the girl during the pregnancy while the other feels left out, which could cause some tension between them.
Another good fanfic is 'The Road to Trust'. It focuses on the slow - building trust between Tony and Bucky. The author does a great job of showing how their different personalities clash at first. Tony's high - tech world and Bucky's old - fashioned values create some interesting conflicts that are resolved in a very satisfying way as they start to respect and trust one another.
I really like 'Bucky's Redemption'. In this fanfic, Bucky is on a journey to fully come to terms with his past actions while Steve is there to support him every step of the way. It shows their loyalty to each other in a very touching way. There are some intense emotional moments as Bucky struggles with his guilt and Steve tries to pull him out of the darkness.
Bucky is usually portrayed as a protective figure. His past traumas make him more empathetic towards Peter's struggles. He is also very resourceful, using his skills to keep Peter safe.
Obviously, Bucky is a main character. He's the one with a complex past that needs to be dealt with. And the therapist is also a main character as they are the ones who will guide Bucky through his emotional and mental journey. There could also be other supporting characters from Bucky's world, like his friends who might interact with him during his therapy process, but the central focus would be on Bucky and the therapist.
