In this fanfiction, the story could start with Wonder Woman being intrigued by the tales of Batman she hears from other heroes. She decides to visit Gotham to see for herself.

However, as they start to interact, they find that they share a common goal of protecting the innocent. They might face a powerful criminal organization that is using advanced technology and magic. Wonder Woman's super strength and combat skills along with Batman's gadgets and strategic mind would make for an exciting story as they battle the bad guys together.
