A fanfiction with Tony Stark having a heart attack during Civil War can open up numerous storylines. It could show the reactions of other characters like Pepper Potts, who would be extremely worried. His fellow Avengers might put aside their differences temporarily to ensure his survival. Also, it could lead to a deeper exploration of Tony's health issues that were perhaps overlooked before the heart attack, and how it affects his future decisions in the ongoing conflict.
One possible plotline is that Tony's heart attack forces the Avengers to take a step back from the Civil War. They might start to question the purpose of their fighting when one of their own is in such a critical state.
One possible scenario in this fanfiction could be that a de - aged Tony Stark brings a new perspective to the events of Civil War. He might be less jaded and more idealistic, trying to find solutions that the older, more conflicted Stark couldn't see. Maybe he forms unexpected alliances with other characters based on his fresh outlook.
One possible plotline could be Tony Stark's struggle to continue being Iron Man after the heart attack. He might have to rely more on his intellect and less on his physical strength, leading to some really creative solutions in his battles. Another could be his friends and teammates rallying around him to support his recovery, which would show the strong bonds in the Marvel universe.
To make it more emotional, describe his physical and mental pain in detail. Show his frustration at not being able to do the things he used to do easily. Include scenes where his friends like Rhodey or Happy visit him in the hospital, and their exchanges are filled with love and concern. Maybe have a moment where he breaks down in front of them, realizing how close to death he was.
In this fanfiction, Tony Stark having a heart attack might force him to reevaluate his life. He might start thinking about all the times he's put himself in danger without much regard for his own well - being. It could also be a turning point for his relationships, like with Pepper Potts. She would be extremely worried and might take more control over his lifestyle to prevent further health issues.
Probably Rhodey. He's been Tony's friend for a long time. They've been through a lot together, and Rhodey would be very worried about Tony's well - being.
The 'daddy kink' in Tony Stark fanfiction might also be related to his intelligence and mentorship qualities. He could be seen as a 'daddy' figure who guides and nurtures the other character, much like a father figure but with a more romantic and sexual undertone. Writers may use this to create complex relationships where the other character looks up to Tony not just as a hero but also as someone they are attracted to on a deeper level. This can lead to some really interesting character development and plot twists in the fanfiction.
In a Westeros fanfiction with Tony Stark, he could potentially form alliances. For example, he might team up with Daenerys Targaryen. His knowledge of engineering could help her build better defenses for her cities, or even improve the design of her dragons' saddles. Also, his charisma and leadership skills could influence the political landscape of Westeros in unexpected ways.
In some fanfictions, Zemo - the one who originally stirred up trouble in the movie Civil War - could still be a major antagonist. He might target Peter specifically to get to Tony or use Peter's inexperience against the heroes.
Fanfiction writers often use Tony's PTSD to add depth to his character. They might show how he tries to use his technology to cure himself. Or how he copes by throwing himself into his work, building more and more suits. It also gives a chance to explore his vulnerability, which is different from his usual confident superhero persona.
