Friendship is also a major theme. Despite their differences, they are often portrayed as having a deep - seated friendship. Fanfics may show them sharing their thoughts and feelings, and relying on each other in tough times.
The theme of sacrifice also pops up. Their relationship is such that they might be willing to sacrifice themselves or their own interests for the sake of the other. This could be in the face of a powerful enemy or a difficult decision that has to be made for the greater good.
Power and responsibility is also a theme. Both Captain America and Iron Man have different views on how to use their power. Fanfictions often play with these ideas, showing how they might influence each other or find a middle ground. For example, some stories might have them debating about the best way to protect the world.
One common theme is the resolution of their differences. Since they had major conflicts in the movies, fanfic might use a kiss as a way to show them making up.

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.

Another theme is the exploration of their different worlds. Iron Man's world of high - tech and corporate influence, and Spider - Man's world of neighborhood - level heroics. Fanfics often bring these two worlds together, showing how Spider - Man adapts to Iron Man's more high - tech environment and how Iron Man learns from Spider - Man's down - to - earth approach.
