One popular Medabots fanfiction could be about a new type of Medabot being discovered. It might involve a young protagonist who stumbles upon this unique Medabot in an unexpected place, like an old abandoned factory. The story could then revolve around the challenges they face in getting it recognized and registered in the Medabot battles.
Another idea is a crossover with Gundam. The Medabots could find themselves in the middle of a Gundam war. They'd have to use their small size and agility to their advantage against the giant Gundam machines. They might also be able to upgrade themselves using Gundam technology.
First, decide which universe you want to crossover with. Then, think about how the Medabots will interact with the elements of that universe. For example, if it's a crossover with Transformers, consider how the Medabots' small size and different abilities will be perceived by the Autobots and Decepticons.
First, think about the characters. Decide if you want to use existing Medabots characters or create your own. Then, come up with a basic plot. It could be a simple adventure where a Medabot and its owner go on a quest.
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.
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.
Well, it could be about the two Megamans teaming up to fight a common enemy. Maybe they combine their unique abilities, like Starforce's EM Wave powers and Rock's classic weaponry, to take on a powerful villain that threatens both of their worlds.
