One common theme is female empowerment. Both Wonder Woman and Black Widow are strong female characters, and in fanfiction, they often team up to show the power of women working together. They break gender norms and prove that they can be just as capable, if not more, than male superheroes.
Friendship or a deeper bond is also a common theme. Since they come from different backgrounds (one from the DC universe and one from the Marvel universe in the original canons), fan fictions like to play with how they form a connection. They might start as strangers but end up as great friends or even more, like sisters in arms, supporting each other through various battles and difficulties.
Romance can also be a theme, although not as common as the others. When it is, it usually shows a relationship that is based on mutual respect and admiration. The fanfictions might explore how they balance their heroic duties with their relationship. It's an interesting take as they are both very independent characters. Also, the theme of sisterhood is present in some works, emphasizing their bond as strong female superheroes in a male - dominated world of superheroes.
A common theme is female empowerment. Since both are strong female characters, the fanfictions often highlight their power and independence. For example, in many stories, they break gender norms and take on challenges that are typically thought of as male - dominated.
For Wonder Woman, you could explore her adapting to a more modern world in the fanfiction. Maybe she has to deal with new technologies and social norms that are different from her homeland. For Black Widow, you could show her past traumas affecting her actions in new ways. For example, her experiences in the Red Room could resurface when she's in a high - pressure situation with Wonder Woman.
One common theme is redemption. Since Natasha has a dark past, many fanfictions explore her journey towards making up for the things she's done. For example, she might try to save people she once targeted.
One great piece of Wonder Woman Black Widow fanfiction can be found on Archive of Our Own. It's titled 'Alliance of the Amazons and the Widow'. In this fic, they team up to fight a common enemy. The story does a great job of showing how their different skills complement each other.
Ares could be a great antagonist. He might see the union of Black Widow and Wonder Woman as a threat to his plans of chaos and war. His god - like powers would pose a significant challenge to the two heroines.
One idea could be that they team up to take on a common enemy who has the ability to manipulate minds. Wonder Woman uses her strength and lasso of truth, while Black Widow uses her espionage skills to outwit the enemy.
One common theme is the clash of their different fighting styles. Black Widow's more stealthy and calculated approach against Daredevil's more impulsive and street - level brawling.
The theme of loyalty also comes up frequently. Whether it's loyalty to the Red Room in her past, or her newfound loyalty to the Avengers later on. Fanfictions play around with how these loyalties shift and develop over time, especially when looking at her past experiences.
