Hawkeye would be a great addition. He could provide long - range support during their adventures. His archery skills combined with Ant - Man's ability to get into tight spots and Captain America's leadership and combat skills would make for an exciting team dynamic.
Another idea for a fanfiction could be set in an alternate universe. Ant - Man is a well - known scientist who creates a device that accidentally gives Captain America the ability to change size too. They then have to deal with the consequences of this new power, both good and bad. It could explore how their friendship changes and how they use this new - found ability to protect the world in a different way.
One possible fanfiction could be about Spider - Man teaming up with Captain America. Maybe Peter Parker looks up to Cap and gets the chance to fight alongside him against a new threat in New York. For example, a group of villains who have stolen some high - tech weapons and are causing chaos. Spider - Man's agility combined with Captain America's leadership and combat skills would make for an exciting story.
In the world of fanfiction, the idea of Iron Man killing Captain America can be quite controversial. Ethically, it goes against the typical heroic and friendly relationship they have in the mainstream Marvel universe. However, fanfiction is a space for exploring different scenarios, so while it may seem unethical to some, it can be a creative exploration for others.
A third common theme is sacrifice. Fanfictions may depict situations where either Captain America or Iron Man has to sacrifice something for the greater good or for the sake of their relationship. It could be something as simple as sacrificing personal time to train together or as big as sacrificing a chance at personal glory to save the other.
One common theme is friendship. Since they are both heroes from the Marvel universe, fanfictions often explore how they become friends and support each other. Another theme is mentorship. Captain America, being from an older era, can sometimes be portrayed as a mentor to Spider - Man.
A recurring theme is the contrast between their personalities. Captain America is more of an old - fashioned, by - the - book hero, while Spider - Man is young and impulsive. Fanfictions often explore how they deal with this difference. Also, the theme of sacrifice is common. They both are willing to sacrifice themselves for the greater good, and this is often highlighted in the stories. For instance, in some fanfictions, one of them will put themselves in danger to save the other or civilians.
One great fanfiction could be about Spider - Man's internal struggle during the events of 'Captain America: Civil War'. He's a new addition to this complex world of superhero politics. He might be initially excited to be part of the fight, but then starts to question the motives of both sides. Maybe he tries to find a middle ground, using his unique perspective as a young hero who hasn't been jaded by years of superhero rivalries.
One idea could be a story where Captain America and Captain Marvel team up to face a new cosmic threat that's headed towards Earth. They have to combine their unique skills, with Captain America's strategic mind and combat experience on the ground, and Captain Marvel's incredible cosmic powers in space battles.
A simple idea could be a friendly sparring match between Spider - Man and Captain America. They both have different fighting styles, and it would be interesting to see how they interact during a non - life - threatening combat situation. Maybe they exchange tips on how to improve their fighting techniques.
