In a time - travel fanfiction to Afghanistan, Tony Stark could go back with the intention of changing the course of events that led to the creation of the first Iron Man suit. Maybe he tries to find a different way to escape captivity without building the weapon - like suit, but instead focuses on creating a more peaceful solution. This could lead to a whole new timeline where the Avengers form under different circumstances.
A simple plot could be that Tony Stark travels back in time to Afghanistan and tries to stop the events that led to his PTSD. He could use his future technology to neutralize the threats before they even start. This would change his character arc in the future as he wouldn't have the same traumas to overcome.
He might be a soldier named Tony who is deployed in Afghanistan. In the fanfiction, he could be sharing his thoughts and feelings about being in a war - zone, the camaraderie among his fellow soldiers, and his views on the mission.
He could become more hardened. The harsh conditions and dangerous situations in Afghanistan might make him less trusting and more cautious. For example, he might be constantly on guard against potential attacks, which changes his personality.
One possible reason could be to rescue a friend or ally who is in trouble there. Maybe someone he knew from his previous time in Afghanistan got caught up in a new conflict or was kidnapped by a local militia.
In the Afghanistan fanfiction, Tony could be talking about the rich cultural heritage of Afghanistan that has been overshadowed by the long - running conflicts. He may mention the beautiful architecture, traditional arts like carpet - making and pottery, and how these cultural elements are struggling to survive in the war - torn environment.
One common theme could be the struggle of the character in an unfamiliar and often hostile environment like Afghanistan while dealing with the unexpected pregnancy. It might explore how Tony copes with the physical and emotional changes during pregnancy in a war - torn setting.
Pepper Potts could be a big help. She knows Tony so well, and she could try to jog his memory by showing him things from their past together, like pictures or mementos. Rhodey could also be there for him. He could tell Tony stories about their military days and how they became friends, which might trigger some memories.
