You could write a fanfiction where the Million Doller Man travels to different dimensions. In these dimensions, he might find versions of himself with different powers or personalities. This would allow for a lot of creative exploration of the character. Or perhaps a story where he has to mentor a young hero - in - training, passing on his knowledge and skills.
A great fanfiction idea could involve the Million Doller Man losing his powers and having to rely on his wits and the help of his friends to get them back. It could show his character development as he struggles without his usual abilities. You could also write a story about his love life, like a secret relationship with someone who doesn't know his true identity.
The Million Doller Man's love interest can be a really popular character to include. It could be someone he met in his civilian life or another hero. Also, his family members, if they exist in the lore, can be interesting to include. They can bring out different sides of his personality. For example, if he has a younger sister, he might be protective of her. And then there are other heroes in the same universe. Collaborating or having a friendly rivalry with them can make for an exciting fanfiction.
A cool fanfiction idea might be to set the Six Million Dollar Man in a different time period. Imagine him being sent back in time to the Wild West or forward to a post - apocalyptic future. He would have to use his abilities in unique ways to adapt to these new and strange environments.
In Iron Man 3 fanfiction, a common theme is the expansion of the Iron Legion. Some stories might have the Iron Legion being used for civilian rescue operations on a large scale. There could also be fanfictions that explore the villains in more detail. For example, exploring Aldrich Killian's backstory more and what led him to become the way he was, and how his relationship with Tony could have been different.
One idea could be a fanfiction where Denji gets transported to a modern-day city outside of his own world. He has to adapt to new technology and deal with a different kind of devil threat. Another could be a story that focuses on Power's past before she met Denji, exploring her time in Hell and how she became the way she is. A third idea might be a fanfiction where Makima is actually a double agent, secretly working against the devils she seems to be controlling.
You could also create a fanfiction where the frozen criminals start to form an alliance within the prison. They come up with a plan to escape and take over the new 'utopian' society, and the story could be about how the hero stops them.
One idea could be exploring Tony Stark's new inventions after the events of previous movies. Maybe he creates a new type of suit that can travel through dimensions.
One idea could be exploring a different timeline where one of the main characters made a different choice at a crucial moment. For example, if Eddie had decided not to pursue music, how would his relationships and life have been different? Another idea is to focus on the backstory of a minor character and how they intersect with the main group. Maybe a character who only appeared briefly has a deep connection to one of the friends that could change the whole dynamic. Also, you could write a fanfiction about a special event that brings the group even closer together, like a trip they take where they face unexpected challenges and grow stronger as a result.
One idea could be exploring a different origin story for Spider - Man in the fanfiction. Maybe he gets his powers from a scientific experiment gone wrong in a completely new way. For example, instead of being bitten by a radioactive spider, he could be exposed to a mutagenic serum that gives him spider - like abilities along with some unique side - effects that he has to deal with.
One idea could be creating an OC (Original Character) who is a young martial artist from a different part of the world coming to Ip Man's school to learn. This OC could bring in new fighting styles and cultural elements, leading to interesting exchanges with Ip Man and his students.
Well, one interesting idea could be the combination of the RWBY universe's unique character abilities with the epic scale of the Man of Steel story. Maybe characters from RWBY having to face challenges similar to what Superman does in Man of Steel, like dealing with powerful foes that threaten their world. Another idea might be the exploration of how the different Dust types in RWBY could interact with the technology and powers in the Man of Steel world.
