One idea could be a group of survivors from different Marvel universes teaming up to find a cure. They might include Spider - Man from an alternate reality, and Black Widow. Another could be a story where the zombified heroes are sent to a different dimension and the non - zombified heroes have to figure out how to bring them back without getting infected.
First, decide on the main characters you want to include. It could be a mix of well - known heroes like Captain America and some lesser - known ones. Then, think about the setting. Will it be in a big city like New York or a more isolated place? After that, come up with a starting point for the zombie outbreak. Maybe it starts in a secret lab.
The fanfiction titled 'A New Hope in Marvel Zombies' is also quite good. It focuses on a group of survivors who are trying to find a cure for the zombie virus and their adventures along the way. They encounter various zombified heroes and villains, which makes for an exciting read. In this story, the character development is well - done as the survivors face numerous challenges and moral dilemmas.
The setting also matters. A good fanfiction might explore different parts of the Marvel world that are affected by the zombies. It could be a story set in a zombified Asgard, or in the seedy underbelly of New York City during the outbreak. And of course, the writing style should be engaging, with vivid descriptions of the gore and horror of the zombie situation, as well as the emotions of the characters involved.
I think in 'Marvel The Flash Crossover Fanfiction', the most interesting part would be how the Flash's abilities are perceived in the Marvel universe. Since the power scales and the overall feel of the two universes are different. Maybe the Flash would be seen as an anomaly, or perhaps a new kind of hero that the Marvel characters have to adapt to. It could also explore how the Flash's speed affects time and space in a world that already has characters like Doctor Strange who are well - versed in such concepts.
One idea could be that Naruto is transported to the Marvel universe and his godlike powers are mistaken for being a new type of mutant. The Avengers might initially be wary of him, but as they see his sense of justice and his willingness to help, they start to work with him. For example, his ability to create countless clones could be used in battle strategies against villains like Thanos.
Once upon a time in a world where Autobots and Avengers co - existed. Optimus Prime teamed up with Iron Man. They were facing a new threat that combined the technology - stealing abilities of the Decepticons and the magic - misusing powers of some Marvel villains. Together, they used their combined intelligence and strength to fight back. Optimus's strength and Iron Man's high - tech gadgets made them a formidable duo.
A cool scenario would be a battle royale - style crossover where Wonder Woman is brought into the Marvel universe to participate in a tournament. She has to fight against various Marvel heroes and villains, like Thor and Loki. As she progresses, she discovers that the real mastermind behind the tournament is trying to use the chaos to open a portal to another dimension. Along the way, she forms alliances with some of the Marvel characters and together they try to stop the evil plan.
One idea could be that Harley Quinn somehow gets transported to the Marvel universe. Maybe she teams up with Deadpool. They both have a crazy and unpredictable nature, so their interactions would be really interesting. They could go on a wild adventure fighting against some common enemy like Doctor Doom who is trying to take over both their worlds or something.
