Well, I'm not sure of the exact title, but there are some fanfictions that explore Steve cheating on Tony in an alternate universe where they have different roles or powers. These often play with the idea of how their relationship dynamics change due to these factors and how the cheating incident still manages to disrupt their lives.
There's also 'Unfaithful Hearts' which focuses on the reactions of their friends and the wider community within the fanfiction world. It's not just about Steve and Tony, but how their situation impacts everyone around them.
Another great one is 'Steve's Grand Proposal'. This fanfiction delves deep into Steve's feelings and his insecurities about whether Tony would say yes. It shows his journey of preparing for the proposal, from writing a heartfelt speech to finding the right time and place. The moment of the proposal is very emotional, with Tony being completely surprised and overjoyed.
One popular 'Steve leaves Tony pregnant' fanfiction might be 'A Changed Path'. In it, the story delves deep into Tony's emotional turmoil after Steve leaves him in such a vulnerable state. It shows how Tony has to face the challenges of pregnancy alone, while also dealing with his feelings of betrayal and heartbreak.
One possible reaction could be Tony's heartbreak. He might feel betrayed and angry, leading to a rift in his relationship with Steve. He could also become distrustful of others in the future.
There are several great ones. 'The Avengers Reunited' is a fanfiction where Steve and Tony work together to face a new threat without any domestic abuse themes. It focuses on their friendship and how they combine their skills to save the day. Another is 'Stark and Rogers: Allies Again' which shows their journey to rebuild trust and cooperation in a positive light.
There are fanfictions where the fight is a result of miscommunication. Maybe Steve thinks Tony is being too controlling with the Avengers, and Tony believes Steve is being too reckless. This misunderstanding can lead to an intense fight scene that many fanfiction writers like to explore.
Tony might cut off his relationship with Steve completely. He's a proud man and wouldn't tolerate such betrayal easily.
Yes, there are quite a few. You can start by looking on fanfiction websites like Archive of Our Own. There, you'll find a variety of stories exploring the relationships between Steve, Bucky, and Tony. Some might focus on the friendship aspect evolving into more complex emotions, while others could be more creative interpretations of their interactions within the Marvel universe.
Another type is the adventure - based fanfictions. 'The Quest for the Lost Artifact' has Steve and Tony teaming up to find a powerful and ancient item. Along the way, they face numerous challenges and in the process, their bond deepens. They learn to rely on each other's strengths, Steve's leadership and physical prowess and Tony's technological genius.
I think this kind of fanfic can be quite controversial. In the Avengers universe, Steve and Tony have a complex relationship, and adding such a plot of 'cheating' with Bucky can change the whole dynamic. Some fans might like it for the drama it creates, but others might feel it goes against the original spirit of the characters' relationships.
One way could be through communication. Steve could come clean to Tony about his feelings for Bucky and apologize sincerely. Tony might be able to forgive Steve over time if he sees that Steve is truly remorseful.
