Another fanfic could be set in an alternate universe where Gotham and New York City are in some sort of alliance. Bruce Wayne and Tony Stark are forced to work together to fight a common enemy that is using both cities' resources for evil. Their different fighting styles and personalities clash at first, but over time they develop a deep respect for each other and become friends.
