One plot idea could be a team - up mission. Tracer, D.Va and Futa could be sent on a top - secret mission to infiltrate an enemy base. They each use their unique skills. Tracer for her time - jumping abilities to quickly navigate the complex, D.Va with her mech for heavy combat, and Futa with some special power yet to be defined in this story. Along the way, they face various challenges and have to learn to work together.
I'm not sure about specific fanfics with exactly those three in this context. However, you can try searching on popular fanfic platforms like Archive of Our Own. Just be sure to check the tags and ratings to find the ones that suit your taste.
One idea could be a story where Dva and Tracer are in a parallel universe where they are part of a racing team together. They start off as rivals in the team but gradually develop a deep friendship that could potentially turn into something more. Another plot could involve them teaming up to save their city from a new kind of digital threat. They use their unique skills, Dva's mech piloting and Tracer's time - jumping abilities, to outwit the enemy.
One idea could be a story where they are on a joint mission. Despite their different personalities and combat styles, they start to rely on each other more and more. As the mission progresses, they discover a common enemy that threatens not just their world but also their new - found friendship. This forces them to work even closer together, leading to a deeper bond.
Another interesting one is 'The D.Va - Tracer Connection'. It delves deep into the in - game lore and how their roles in Overwatch could lead to a romantic relationship. It shows their unique skills complementing each other in both combat and personal growth.
Writing such fanfic is completely inappropriate. 'Overwatch' is a game with a wide audience, including many young players. Creating or promoting sexualized fanfic about its characters goes against ethical and moral standards, and can also be offensive to the game's fans and the general public.
One interesting Tracer fanfiction might be about her having a day off and exploring a new part of the Overwatch world in a light - hearted, lemon - themed adventure. It could involve her meeting new characters and having some comical and slightly romantic encounters.
One idea could be that the RWBY characters are transported into the Overwatch universe and have to team up with the Overwatch heroes to fight a new common enemy, like a powerful omnic - Grimm hybrid. Another could be a friendly competition between the two groups in a series of combat trials to see who is more skilled.
One idea could be Neo using her unique abilities in unexpected ways to help the team in a new adventure. Maybe she discovers a new form of her Semblance that gives her an edge in combat.
Well, a great plot might be that Blake discovers a hidden power within herself. This power could attract both friends and foes alike. She might have to deal with the jealousy of some of her comrades while also trying to master this new ability. Or perhaps she gets caught in a political intrigue between different kingdoms in Remnant, and her actions as a Futa character could bring a new perspective to the story.
Some Overwatch - related forums and communities might also have links to or discussions about Tracer x D.Va fanfictions. For example, the official Overwatch forums or some dedicated Overwatch fan communities on Reddit.
