There are also themes related to their different backgrounds and how those differences play out in their interactions. For instance, BJ being from a different part of the country than Hawkeye, and how they learn from each other's cultures and ways of thinking.

Adventure is another common theme. Writers like to send them on exciting quests or exploration in the world of Equestria.

They learn new things about themselves and each other during these adventures.

Also, some fanfictions may explore the psychological after - effects of the war on the characters, like dealing with PTSD or survivor's guilt.
