One great story could be about Junkrat and Symmetra teaming up in a match. Junkrat's chaotic playstyle might accidentally disrupt the enemy's formation just in time for Symmetra to set up her sentry turrets for an easy kill. They might not seem like an obvious duo at first, but their unique abilities can complement each other well in the right situations.
In some stories, Junkrat's grenades can create distractions that allow Symmetra to move her sentries into better positions unnoticed. For example, if the enemy is focused on avoiding Junkrat's explosives, Symmetra can quietly place her turrets in key areas for maximum damage.
One common theme is their friendship. They are often depicted as having a strong bond in the game, and fanfics expand on that. Another theme is adventure. Since they are characters from Overwatch, they might go on various missions together in the stories.
Another theme is the idea of redemption or change. Sombra might be seen as a character who could help Symmetra break out of her very strict ways, or Symmetra could be the one to make Sombra more responsible. It's about how they influence each other's growth.
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 great Symmetra x Sombra fanfiction could be one where they team up for a secret mission. They start off distrusting each other because of their different backgrounds and loyalties. Symmetra, being from Vishkar, is all about order and structure, while Sombra is more of a chaotic figure. But as the mission progresses, they begin to understand and respect each other's skills. Eventually, they form a bond that is both a friendship and something more. Another interesting fanfiction might be set in a post - war world where they have to rebuild together. Symmetra uses her hard - light constructs to build, and Sombra uses her hacking skills to secure the new infrastructure.
In many fanfics, their different worldviews collide in a fascinating way. Sombra's more cynical view of the world and Symmetra's idealistic one can lead to great stories of conflict and resolution. For example, in some fanfics, they start off at odds but then find common ground and grow closer as a result.
A great fanfic to check out is 'Sombra's Discovery of Symmetra'. This one delves into how Sombra, with her inquisitive nature, starts to notice Symmetra's unique qualities and how their relationship unfolds from there. It has some really interesting character development moments.
