In the comics, Iron Man doesn't end up killing Captain America. Their battles and disputes have various outcomes, but not one that involves a fatal blow from Iron Man.

Yes, in some storylines, Iron Man has come out on top in their battles.

Yes, Iron Man 1 did have the image of Captain America's shield.

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 interesting fanfiction could be where Captain America and Iron Man have to team up in an alternate universe to fight a new threat that combines their worst enemies' powers. It could explore their relationship in a different setting, highlighting their differences and how they overcome them to save the day.

It's hard to say for sure. Both Iron Man and Captain America have their unique skills and strengths. It would depend on a lot of factors like the situation, their equipment, and strategy.
