One common theme is their unwavering loyalty. In most fanfics, Steve and Natasha are shown to be completely loyal to each other, always having each other's backs during the events of Infinity War.
One great Steve Natasha Infinity War fanfic is 'Red and Blue in the Endgame'. It beautifully explores their relationship during the chaos of Infinity War. The author does a wonderful job of showing their unspoken connection.
The theme of hope also pops up. Despite the doom and gloom of Infinity War, Bruce and Natasha in fanfictions can be a source of hope for each other. They might find small moments of victory or connection that give them the strength to keep fighting against Thanos and his forces. Their relationship can be seen as a glimmer of hope in the otherwise dark events of Infinity War.
The theme of sacrifice also often appears. Given that they are in the middle of a war, there are times when they have to make difficult choices. They might sacrifice their own safety or even their own identities to achieve a greater goal for the war effort. Their 'ghost - like' existence sometimes means they are willing to disappear completely if it means victory.
One common theme is trust. After the Civil War, they have to re - establish trust in each other and in themselves. Another theme is redemption. They both feel guilty about their actions during the war and are seeking a way to make up for it.
One great plotline could be Natasha and Steve teaming up in a covert mission during the events of Infinity War that wasn't shown in the movie. They might discover a hidden weakness of Thanos and try to exploit it. Another could be a story focused on their relationship development in the midst of the chaos of the war, like how they support each other through the tough decisions they have to make.
Love and family are very common themes. It's about Natasha and Steve building a family together, so there's a lot of focus on their relationship growing deeper through this new chapter.
One common theme is adventure. Given their roles in the Marvel universe as heroes, many fanfics put them in exciting new adventures together. Another theme is romance, of course, exploring their relationship in different ways, like a slow - burn love story.
One common theme is the idea of sacrifice. They are often put in situations where they have to sacrifice their own well - being for the greater good, and then deal with the consequences of that sacrifice in terms of physical and emotional pain.
Often, they're portrayed as very close friends with a deep understanding of each other. They trust one another completely and are always there to have each other's backs in dangerous situations.
Well, 'Frozen Moments' is a really good Steve x Natasha fanfic. It captures their unspoken emotions through various frozen moments in time. 'The Unspoken Alliance' is also interesting as it shows how they form a silent partnership that gradually turns into something more. And 'Silent Support' where they support each other through difficult missions without many words but with a lot of unsaid feelings.
