One of the most popular pairings is Widowmaker and the Sniper. They are both skilled marksmen in their respective universes. In fanfiction, they might engage in a sniper - off or be forced to work together on a mission that requires their precise shooting skills. Genji and the Spy also make an interesting pairing. Genji's ninja - like abilities and the Spy's stealth could lead to some really cool stealth - based missions or battles. And then there's Winston and the Pyro. The contrast between Winston's scientific - minded, yet beastly nature and the Pyro's crazy, unpredictable behavior can create some really unique and humorous storylines.
Soldier: 76 and the Soldier from Team Fortress 2 can be a great pairing. They share the name 'Soldier' and both have a military - like attitude. In fanfiction, they could either be rivals, constantly trying to outdo each other in combat and strategy, or they could become comrades, learning from each other's experiences. Lucio and the Engineer also make for an interesting combination. Lucio's music - based abilities and the Engineer's mechanical know - how could lead to some creative scenarios. Maybe Lucio's music could power up some of the Engineer's inventions or they could collaborate on building a new device that combines their skills.
In RWBY and Team Fortress 2 fanfiction, Ruby and the Engineer could be a popular pairing. Ruby's fascination with weapons and the Engineer's talent for building and inventing could lead to some great stories. Weiss and the Medic might also be a popular choice. Weiss' need for perfection and the Medic's scientific approach could be an interesting combination. And Blake and the Sniper could be a pairing that fans like. Blake's stealthy nature and the Sniper's long - range precision could create some exciting scenarios.
Well, in many Team Fortress 2 crossover fanfictions, the Medic is a very popular character to feature. He has a unique look and his role as a healer gives him a special place in crossovers. He can be paired with other characters from different universes who need his medical expertise. The Demoman is also quite popular. His wild and explosive personality can bring chaos to any crossover story. He might introduce his bombs and demolitions skills to a new world. And of course, the Soldier. His patriotism and his over - the - top military antics can create really funny and action - packed crossovers.
I think Mercy and Ruby would make an interesting pairing. Mercy is a healer in Overwatch and Ruby is the leader of Team RWBY. Ruby could learn about Mercy's advanced medical technology and how she uses it in combat. Meanwhile, Mercy could be inspired by Ruby's determination and leadership. Another great pairing could be Winston and Yang. Winston is a brilliant scientist and a powerful fighter as a gorilla. Yang is a brawler with a lot of strength. They could have some epic sparring sessions and also exchange knowledge about strength - based fighting and scientific inventions.
The Soldier is quite popular in Team Fortress 2 crossover fanfic. His patriotism and his over - the - top military style can be really interesting when combined with other military - themed characters from different franchises. Also, his rocket launcher can lead to some really explosive and action - packed scenes in crossovers. The Demoman is also a favorite. His love for explosives and his one - eyed, drunken - pirate - like appearance can be a great addition to many crossover stories, especially when paired with other rowdy or explosive - loving characters.
Pyro is another favorite. Since his identity is mostly hidden and his actions are a bit unpredictable, fanfiction writers have a lot of freedom to create different interpretations of him. Some might write about him having a gentle side beneath the mask, while others might explore his more chaotic and violent tendencies in a more detailed way.
One of the most interesting pairings would be Reinhardt and Pyrrha. Reinhardt is a knight - like character in Overwatch, and Pyrrha was a very skilled fighter in RWBY. They both have a strong sense of honor. Reinhardt could teach Pyrrha some of his combat techniques from the Overwatch world, and Pyrrha could show Reinhardt some of the unique fighting styles in RWBY. Also, Widowmaker and Weiss could be an unexpected but fascinating pairing. Widowmaker's cold - blooded assassin nature could contrast with Weiss' more noble upbringing, and they could learn from each other in terms of combat and strategy.
Medic from TF2 and Mercy from Overwatch. They're both healers, but they have very different approaches. Medic is a bit more... unorthodox with his healing methods, like using his Medi - Gun. Mercy, on the other hand, is more angelic and serene. It would be fascinating to see how they interact, perhaps they could learn from each other's techniques and develop new ways to heal the combined team during a tough battle.
Mercy and Doc would also be a great pairing. They are both medical personnel in their respective universes. They could exchange medical knowledge, with Mercy teaching Doc about some of the more advanced medical technology in the Overwatch universe, and Doc showing Mercy some of his improvised medical techniques that he's developed in the Red vs Blue world.
Sans and Ruby are quite popular. Ruby's enthusiasm and Sans' nonchalant attitude can create a really interesting dynamic. They're both important characters in their respective worlds, so fans like to explore how they would interact.
Mario and Sonic themselves are often paired up. They are the two main characters from their respective franchises, so it makes sense that fans like to write about their interactions. They can be rivals, friends, or reluctant allies in different fanfictions.
