Well, Witchblade and Darkness fanfiction can vary a great deal. One aspect could be the art of world - building. Writers might combine the gritty, dark world of Darkness with the more supernatural elements of Witchblade. They could also play with the character relationships. Maybe a hero from one series forms an alliance or a rivalry with a character from the other. It really depends on the creativity of the fanfic author.
The number of Witchblade comics can vary. It's influenced by factors like reprints and special editions. But you might be able to find a more accurate count on dedicated comic databases or from the publisher's information.
One popular theme is power struggles. Given the powerful nature of the Witchblade and the Darkness, it's common to see stories where characters vie for control over these forces. Another theme is redemption. A character who has been corrupted by either the Witchblade or the Darkness might seek to atone. And of course, there's the theme of love and relationships, whether it's a forbidden love between characters from different sides of the Witchblade and Darkness divide or a friendship that endures despite the chaos.
