A frequent theme is the struggle for acceptance. Since the OC is new, they sometimes have to prove themselves to the established Overwatch members. Also, heroism is a big theme. The OC usually tries to do heroic deeds, whether it's saving a city from a new threat or helping out in a humanitarian crisis within the Overwatch world. Additionally, there can be themes of redemption, especially if the OC has a past they are not proud of.
Well, redemption can also be a theme. Maybe the OC has a past they are not proud of and they are seeking redemption through their actions in the Overwatch universe. And there's often the theme of adaptation. The OC has to adapt to the high - tech and chaotic world of Overwatch, with all its different cultures and species. This can lead to some humorous and also poignant moments in the fanfiction as they learn to navigate this new world.
Another theme is the exploration of different game mechanics. Writers often play with the idea of how the TF2's class - based system and Overwatch's hero - based system could coexist or clash in a fanfic story. It can lead to really interesting scenarios and battles. And also, the theme of teamwork or lack thereof between the two groups is often explored. Since both games have elements of teamwork, seeing how the characters from different games work together or against each other is quite fascinating in fanfics.
Teamwork is another big theme. Both Naruto and Overwatch emphasize the importance of working together. Fanfics will show how characters from both universes come together to form teams. They might have to overcome differences in fighting styles and ideologies to achieve a common goal, like protecting a city or defeating a powerful enemy.
One common theme is the 'opposites attract' idea. Since Roadhog has his tough and menacing appearance, an OC might be a more gentle or naive character, and their relationship develops from that contrast. Another theme could be redemption. The OC might help Roadhog find a new purpose or a way to atone for his past actions in the Overwatch lore.
One common theme is the healer - patient relationship. Since Mercy is a healer in Overwatch, often the OC is in need of her medical assistance, which then leads to a deeper connection. Another theme is the exploration of Mercy's angelic nature and how the OC relates to it, like being inspired by her or having a spiritual connection.
Another theme is the idea of heroism. Both Overwatch and Spiderman are about heroes, and in these fanfics, they usually combine their heroics. For example, they might fight a common enemy that neither could defeat alone. It shows that different types of heroes can work together for the greater good.
One common theme is the redemption arc. Given Reaper's rather dark and brooding nature, many fanfics explore the idea of Mercy helping him find redemption. For example, she might try to heal not just his physical wounds but also his damaged soul.
One common theme is loyalty. They are often shown as being extremely loyal to each other in the face of danger. For example, in many fanfics, Roadhog will always have Junkrat's back and vice versa.
One common theme could be the idea of new beginnings. Mercy's pregnancy represents a new life, and the fanfic could explore how this changes her perspective on things. Another theme might be support. It could show how the other Overwatch characters support her during her pregnancy, like bringing her things she needs or just being there to listen.
One common theme is friendship. Since there are three OCs, their relationships with each other often form a big part of the story, like in 'The Trio's Friendship' where they rely on each other through thick and thin.
