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.
Definitely Loki. He's a fan favorite and can easily fit into various crossovers. His mischievous nature can add a lot of twists to a story. For example, if he were to cross paths with the Fantastic Four, he could play all sorts of mind games with Reed Richards while also being intrigued by Sue Storm's powers.
One great idea could be a crossover between the X - Men and the Avengers. Imagine Wolverine teaming up with Captain America, their different fighting styles and moral compasses would create an interesting dynamic. Wolverine's rough - and - tumble, lone - wolf approach contrasting with Captain America's more traditional leadership and sense of justice.
The 'Civil War' storyline is also a top - notch crossover. It divided the superhero community over the Superhuman Registration Act. This led to intense battles between heroes like Iron Man and Captain America, and explored complex moral and political issues within the Marvel Universe.
DC and Marvel have had some crossover events in comics. They usually happen as special limited series or one-shot issues to generate buzz and appeal to fans of both franchises.
There are a few novels with invincible protagonists who have transmigrated to the Marvel World. I recommend the following to you:
"The Unrivaled Dominator of the American Comics": The protagonist Xie Yun obtained an Unrivaled Dominator System and traveled to the Marvel Universe, becoming the most eye-catching man in the Marvel Universe.
[Marvel's Alien Sword Immortal: The main character is a cultivator who re-cultivates in the Marvel world. He is free in this world and has powerful abilities.
"Marvel Venom Devours All Worlds": The protagonist Kubei transmigrated into Marvel Venom and obtained the Heaven Traversing System, possessing various powerful abilities.
I hope you like the novel recommendations above. Muah ~
Superman could fit into the Marvel Universe in several ways in fanfiction. Firstly, his origin could be tweaked a bit. He could be an experiment gone wrong in a Stark Industries lab that gave him his powers. This would immediately connect him to the Marvel world. His powers would still be his trademark ones like flight, super strength, etc. He could then become a sort of protector of a particular city in the Marvel Universe, like New York. He would interact with the local heroes and villains. His presence would disrupt the power balance a bit, and some villains might target him specifically. But with his unwavering moral compass, he would stand up to them and become an important part of the Marvel Universe's tapestry of heroes.
One great DC Marvel crossover fanfic is 'The Avengers and the Justice League: United Front'. It has an exciting plot where the two teams come together to fight a common, powerful enemy. The character interactions are well - written, especially the exchanges between Superman and Captain America, who share similar leadership qualities.
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.
Definitely 'Civil War'. It's not only a great story but also has a huge impact on the Marvel universe. The battles between Iron Man and Captain America are iconic. 'Secret Wars' is also excellent. It has a really cool concept of different worlds colliding. The art in it is also amazing. 'X - Men: Days of Future Past' is another good one. It shows a dystopian future where mutants are hunted and how the X - Men try to prevent it from happening.
