One common theme is the idea of cooperation between two very different characters. Naruto, with his ninja skills and strong will, and Mercy, with her healing powers and angelic nature. They often have to work together to overcome challenges.
Another theme is the exploration of different universes. Since they are from different fictional worlds, many fanfictions play with the concept of how they would interact if their worlds collided. For example, how Mercy would react to the shinobi way of life in Naruto's world and vice versa.
The theme of redemption also pops up sometimes. Maybe Naruto helps Mercy find a new purpose or Mercy helps Naruto deal with some of his inner demons. It's about how their meeting can lead to positive changes in their lives and in the situations around them.
Another theme could be growth. Both Naruto and Mercy have their own growth arcs in their respective universes, and in fanfiction, their combined growth as they interact is a popular concept. For example, they might learn new skills or gain new insights through their relationship.
One common theme is redemption. Genji has a complex past and Mercy's presence can often be a part of his journey towards redemption. Another theme is the power of love and friendship. They support each other in the dangerous world of Overwatch, and their relationship is often depicted as a source of strength.
One common theme could be the anticipation and excitement of new life. It might show how Mercy and the people around her are preparing for the baby. Another theme could be the challenges she faces, like balancing her usual responsibilities with the needs of pregnancy.
A common theme is friendship. They are both characters from Overwatch and many fanfictions explore how they become friends, sharing their hopes and dreams. For example, they might talk about their different reasons for being part of Overwatch while having a cup of coffee in the base.
Protection is also a major theme. McCree feels the need to protect Mercy from the dangers of the world they live in, while Mercy protects McCree in her own way, by healing his physical and sometimes emotional wounds.
A theme of mutual understanding also pops up a lot. Given their different personalities and roles in Overwatch, they have to understand each other's perspectives. For example, Mercy's more calm and scientific approach compared to Tracer's more impulsive and action - oriented style. Their fanfictions often explore how they bridge these differences.
Love and mutual understanding are also quite common. The OC might initially be misunderstood by Mercy or vice versa, but as the story progresses, they come to understand each other deeply. And of course, the theme of self - discovery. The OC may discover new aspects of themselves through their interactions with Mercy, like finding a new purpose in life.
Another theme is the power dynamic. Reaper has his dark and powerful abilities, while Mercy is a healer. Fanfictions often play with how these two different power sets interact, whether it's Reaper protecting Mercy in his own way or Mercy using her healing to save Reaper from his self - destructive tendencies.
One common theme is the contrast between their personalities. Roadhog is often seen as rough and tough while Mercy is gentle and kind. Another theme is redemption. Sometimes Roadhog is portrayed as having a troubled past that Mercy helps him overcome. And of course, there's the theme of unlikely relationships. They seem like an odd couple at first, but the fictions often explore how they can form a strong bond.
Family is another important theme. It shows how the baby brings the family closer together, including Mercy's relationship with her mate and the extended pack family. The fanfics explore how they all support each other in raising the baby.
