One idea could be Philippe's adventures after being freed from the mask. He could explore the world, discover new cultures and make friends. Another could be a love story where he meets someone who sees past his past and they fall in love.
One idea could be to explore the backstory of the man in the iron mask more deeply. Maybe he has a secret family or a hidden past relationship that could change the whole perspective of his imprisonment. Another plot could involve a character who tries to rescue him not for political reasons but out of pure moral obligation and friendship.
A strong - willed female character would be great. For example, a noblewoman who is also fighting for justice in the kingdom. She could be his ally and perhaps develop romantic feelings for him as they work together.
A great idea for 'Man in the Iron Mask' fanfiction would be to focus on the relationships within the prison. How did the guards interact with the man in the iron mask? What if there was a sympathetic guard who secretly helped him? You could also introduce other prisoners who befriend the man in the iron mask and together they plan an elaborate escape. This would add more depth to the story and show different perspectives within the prison walls.
One idea could be to explore his origin story in more depth. Maybe he has a hidden family or a past trauma that shaped him into the man of iron. Another could be to put him in a different time period, like the future where technology has advanced even more and he has to adapt.
In some Iron Man harem fanfiction, it could be that Tony Stark is transported to an alternate dimension where the rules of relationships are different. There, he finds himself surrounded by female characters who are all vying for his attention. The story could explore how he navigates this new world and these new relationships while still trying to be the hero he is.
Well, a plot idea could be that in the fanfiction, the events of Iron Man 3 somehow get re - written in a way that Tony Stark's suits in that movie have a different origin. For example, they were actually created by an ancient civilization that he discovers accidentally, and this new knowledge ties into the Avengers' overall story arc. Also, we could have a story where the Extremis virus from Iron Man 3 spreads in a different way and starts to affect some of the other Avengers. This would force Iron Man to not only deal with his own problems related to the virus but also find a cure for his teammates. And then there's the idea of a parallel universe where Iron Man 3 never happened as we know it, but the Avengers are still dealing with the consequences of a similar threat, and they have to rely on Iron Man's knowledge from that 'alternate' Iron Man 3.
One idea could be Jarvis getting a physical form and having to learn how to interact in the real world like a human. He could struggle with emotions and social cues, creating humorous and touching moments as Iron Man tries to guide him.
A plot could also revolve around a time when Rescue's identity is compromised. Iron Man has to protect her while also trying to figure out who is behind the leak. They go on a journey that takes them to different parts of the world, facing various threats along the way. This would test their relationship and their ability to trust each other in difficult situations.
Well, there could be a story where Iron Man and Nebula find themselves in an alternate universe. In this universe, they are the only ones who remember their original selves. They have to find a way to get back home while also dealing with the strange new versions of their friends and enemies. It could involve a lot of action and some really interesting character interactions as they try to adapt to this new and unfamiliar world.
One interesting plot idea could be Iron Man reacting to an alternate version of himself from a parallel universe. Maybe this other Iron Man has different tech or a different moral code, and the real Iron Man has to decide how to deal with this new version of himself.
