Well, 'Mega Man and Kirby: Dream Team Crossover' is a cool one. In this fanfic, Kirby's ability to copy powers and Mega Man's weapon - collecting skills make for an exciting adventure. 'Mega Man meets Zelda' is also quite popular. It blends the high - tech world of Mega Man with the magical realm of Zelda, like Mega Man might encounter Link and they team up to fight against a common enemy that threatens both their worlds.
In Mega Man fanfiction, Bass is often depicted as a complex character. He is a powerful rival to Mega Man. Their relationship can be explored in various ways. Sometimes Bass is shown as a pure antagonist, driven by his desire to prove his superiority. In other stories, there might be a more nuanced relationship where they could potentially find common ground or be forced to work together against a greater threat.
One of the most popular pairings is Mega Man and Roll. It's a classic pairing within the Mega Man universe itself, and in crossovers, it can add an emotional depth to the story. For example, if they are in a dangerous situation in a crossover world, their relationship can be further explored as they protect each other.
One interesting concept is seeing Mega Man interact with characters from other game universes. For example, his encounter with Sonic could lead to some really cool action scenes. They could compete in a race or team up against a common enemy like Dr. Eggman and Dr. Wily combined.
The pairing of Bass x Mega Man in fanfiction can symbolize a lot. It can represent the eternal struggle between good and evil, with Mega Man as the hero and Bass as the anti - hero or villain. Their relationship is like a yin - yang, constantly in opposition yet also interconnected.
One idea could be that Sonic and Mega Man have to team up to stop a new villain who has the power to control both the robotic and natural elements. This villain is creating chaos in both their worlds. Another idea is a race between Sonic and Mega Man's robotic companions, like Tails and Rush, to see who is faster at a series of challenges. A third idea could be that Sonic accidentally enters Mega Man's world and has to learn how to fight the robotic enemies there, with Mega Man as his guide.
One interesting concept could be the combination of Mega Man's robotic abilities and Samus' exploration skills. For example, Mega Man might use his arm cannon in the more maze - like environments typical of Metroid games. Another concept could be the meeting of their respective villains. Dr. Wily and the Space Pirates could form an alliance, creating a greater threat for the heroes to overcome.
Maybe in the fanfiction, Naruto is sent to the world of Mega Man. He has to learn how to use Mega Man's weapons while also teaching the characters in that world about chakra. A plot could involve a powerful villain who wants to use Naruto's chakra to power up his machines. Naruto, with the help of Mega Man and his friends like Roll, has to stop this villain before he destroys both worlds. They would combine Naruto's ninjutsu with Mega Man's shooting and platform - jumping skills to succeed.
Naruto and Mega Man themselves are often the most popular crossover characters. Since they are the main protagonists of their respective series, fans love to see how they interact. Another popular one could be Rockman (Mega Man) interacting with Sasuke. The contrast between Rockman's more robotic and logical nature and Sasuke's brooding and power - hungry personality can create some interesting dynamics.
Definitely Mega Man and Samus are the most popular. They are the main protagonists of their respective series, so it's natural that they take center stage in the crossovers. Their contrasting yet complementary abilities make for great storylines.
