What are some interesting ideas for an Initial D crossover fanfic?

One idea could be to cross Vampire Hunter D with a post - apocalyptic world setting from another series. D could be on a quest to find a vampire lord who has the key to a cure for a virus that has decimated humanity. He would face both vampires and mutated creatures along the way.

To start an Initial D crossover fanfic, it's important to have a clear goal for the story. Are you aiming for a light - hearted, fun racing adventure or a more serious, high - stakes competition? Once you've decided, start building the world. This means combining the settings of Initial D, such as the mountain passes, with the new environment from the crossover. You can introduce new rules for the races that incorporate elements from both universes. For instance, if it's a crossover with a superhero universe, maybe the races are affected by superpowers in some way. Then, start writing the first scene, which could be a teaser of what's to come in the exciting crossover.

Racing competitions are a common theme. Whether it's against new opponents from the crossed - over universe or in a combined racing event. For example, if crossed with another racing anime, the characters will often compete to prove who has the best driving skills.

One idea could be to cross Yu - Gi - Oh 5D's with another popular card game universe. For example, characters from 5D's could meet characters from Magic: The Gathering. They could have a friendly card battle tournament where the rules are a mix of both games, creating unique and exciting duels.

One idea could be to create an alternate universe where the Avengers have different powers. For example, Iron Man could have telepathic powers instead of his high - tech suit. Another idea is to write a story about the Avengers' origin from a different perspective, like from the view of a bystander who witnesses their formation. You could also focus on a single Avenger and their personal journey within the team, such as Black Widow dealing with her past while on a mission with the others.

A crossover with Fullmetal Alchemist could also be fascinating. Picture Edward Elric and the D Gray - Man characters collaborating to understand the mysteries of the Gate and the Innocence. Maybe they find out that there are connections between the two in terms of the source of power and the balance of the world. They could also face off against enemies that are a combination of Homunculi and Akuma.

One idea could be a crossover with 'Cardcaptor Sakura'. Daisuke could meet Sakura and they could both discover that their magical artifacts have some strange connection. For example, the Dark and the Clow Cards might react to each other in unexpected ways.

A crossover with the DC universe would be cool. Imagine Luffy meeting Superman. Luffy would be so excited to meet someone so strong and would probably challenge him to a friendly fight. Or a crossover with the Pokémon world. Luffy and his crew could explore the Pokémon regions, with Luffy trying to befriend all the Pokémon he meets, thinking they're like strange and cool animals. And the Pokémon trainers would be very confused by this strange group of people who seem to have such different powers.

How about a crossover with a post - apocalyptic anime? In this scenario, the world has already been mostly destroyed by the Akuma. The remaining survivors from different animes, including D.Gray - Man, have to band together. The Exorcists would not only be fighting the Akuma but also dealing with the new threats that come with a post - apocalyptic environment, like rival groups of survivors and mutated creatures.

A crossover with "Castlevania" would also be cool. D could find himself in the world of Castlevania, dealing with the various dark creatures there. He might have to navigate the complex politics between the vampires and the humans in that universe.
