Another interesting fanfiction could explore Cutman's origin in the Megaman X universe. Maybe he was created by a different scientist than the original Cutman in the classic Megaman series. This backstory could add depth to his character and his relationship with Megaman X as they discover their shared purpose of protecting the world from threats.
Think about the setting. Is it in a post - apocalyptic world like in some parts of the Megaman X series? Or a more utopian place that's being threatened? For the characters, give them growth. Maybe Cutman overcomes his fear of a certain enemy. Write in a way that shows their personalities. Megaman X could be serious and focused, while Cutman is more light - hearted but determined. Use vivid descriptions to make the story come alive.
One popular fanfiction might be those that explore the relationship between the original Megaman and Megaman X in different timelines. For example, a story could focus on how X was created based on the original Megaman's design, and how their powers and abilities compare and contrast.
One idea could be a crossover adventure where Megaman X and Samus team up to fight a common enemy that threatens both of their worlds. They could start off as rivals, not trusting each other's methods at first, but as they face challenges together, they learn to respect and rely on one another.
Dr. Wily could be the main villain. He might have found a way to travel through time or dimensions to the world of Mega Man X. He then uses his knowledge of Mega Man's weaknesses and combines it with new technology in the Mega Man X world to create even more powerful and devious robots.
Perhaps in the fanfiction, Mega Man and Mega Man X meet in a virtual world created by a mad scientist. The virtual world is filled with distorted versions of their old enemies. They have to work together to find the core of this virtual world and shut it down. Along the way, they share their experiences and upgrade each other's abilities, leading to a new and more powerful form for both of them when they finally face the scientist.
It contributes by expanding the lore. Fanfictions can create new backstories for Protoman and Megaman, filling in gaps that the official games might not have covered. For example, their relationship before a certain event in the game timeline can be explored.
There could be epic battles. Maybe the characters from Megaman Starforce and Megaman X would team up to fight a powerful common enemy. They might combine their unique abilities, like the Starforce's EM Wave powers and X's advanced weaponry.
One key element is the contrast between Rock and X. Rock is more of a classic hero from an earlier era, while X has a more complex backstory. Their different personalities often lead to interesting interactions. Another element is the merging of their worlds. Since they come from different parts of the Megaman universe, how the fanfiction writer combines their settings is important.
One common theme could be friendship. They might be shown supporting each other through various challenges. Another theme could be teamwork, especially if they are in a situation where they need to combine their skills.
