It can start with a common enemy. They are forced to work together against a threat that targets both Gotham and Raven's world. As they fight side by side, they begin to trust each other.
Fanfic writers can develop their friendship through shared experiences. Maybe they both get trapped in an alternate dimension. During their time there, they have to rely on each other's skills. Batman uses his physical and mental prowess while Raven uses her magic to find a way out. This mutual dependence deepens their bond. Also, conversations about their different moral codes can bring them closer. Raven's complex view on good and evil due to her demonic heritage and Batman's strict no - killing rule can lead to interesting discussions and a better understanding between them.
Another way is through helping each other in personal growth. Raven could help Batman become more in touch with his emotions, which he usually suppresses. Batman could teach Raven how to better protect herself in non - magical ways. For example, hand - to - hand combat training. This exchange of knowledge and support would strengthen their friendship over time in the fanfic.
