In fanfiction, Selina Kyle could be an ideal wife for Bruce Wayne. Their relationship in the Batman lore has always been complex and filled with attraction. In a married life in fanfiction, she could bring out a different side of Bruce, as she understands his dual life to some extent, being a cat burglar herself. They could have a relationship full of mystery and passion.
It would probably be a very secretive event. Since Batman has so many enemies, he would want to keep the location and time of the wedding under wraps. Only his closest allies would be invited.
He could marry an original character created specifically for the fanfiction. This character could be a powerful mage from a far - off place who crosses paths with Natsu during one of his adventures.
Her spouse could be a nature spirit. Since Artemis is closely associated with nature, a nature spirit would be a fitting partner. They could understand her love for the forest and all living things.
A new, unknown villain. Maybe a brilliant scientist who turns to the dark side after a personal tragedy. This villain could create a weapon specifically designed to counter Batman's abilities, like a suit that can absorb all of Batman's punches and then redirect the force back at him, ultimately killing him.
The Joker could be a great antagonist. He might be jealous of Batman's new relationship and see it as an opportunity to cause chaos. He could try to drive a wedge between Batman and Poison Ivy, using his mind games and unpredictable nature to create misunderstandings and conflicts within their marriage.
