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.
Dva's pride in her heritage and her love for her country can be part of her character portrayal. This could come out when she and Tracer are on a mission in Dva's homeland. Tracer, on the other hand, her loyalty to her friends and her sense of justice are important aspects. In a fanfic, when they are faced with a difficult decision, Tracer's sense of justice might clash with Dva's more practical approach, but in the end they find a way to combine their ideas. Also, Dva's sassiness and Tracer's cheeky charm can add a lot of flavor to their interactions.
