The main character is Bucky, as the story seems to revolve around him and his need for therapy. The therapist is another key character. They are the one who is going to help Bucky face his inner demons. Depending on the fanfic, there might be cameos or mentions of other characters from the related universe, but Bucky and the therapist are the main focus, with the story likely exploring their dynamic, the therapist's attempts to understand Bucky, and Bucky's struggle to open up and heal.
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.
A 'bucky therapist fanfic' could be about Bucky, perhaps from the Marvel universe, having interactions with a therapist. It might explore his mental state, traumas, and the process of healing through his sessions with the therapist.
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.
Tony Stark could be another important character. He has been a sort of mentor to Peter in the original stories. In this fanfic, he might be a bit jealous at first that Bucky has this new role in Peter's life. But eventually, he could also contribute to Peter's growth, perhaps by providing new technology for Peter's Spider - Man suit in light of Bucky's more hands - on combat training.
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.
The main characters are clearly Bucky and Steve. Bucky is often a complex character with a troubled past, and Steve is known for his strong moral compass and leadership. In this fanfic, they are likely to be the central focus of the story.
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.
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.
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.
The main character is Bucky O'Hare himself. There are also his crew members like Jenny, the android. And there's Willy DuWitt, a human who gets involved in their adventures.
Another possibility is a new villain who has the power to control Bucky's actions. This villain could be after Tony for his wealth or his influence in the superhero community. The villain forces Bucky to do the dirty work while staying in the shadows.
