One common theme is identity. Since Genji has a complex backstory as a male character in the original, a female Genji would likely have to deal with different expectations and self - discovery. Another theme could be relationships, such as her friendships or potential romances with other Overwatch characters.
There are often fanfiction communities on Reddit dedicated to Overwatch. Subreddits like r/OverwatchFanFiction might be a great place to start. People sometimes share their own works or recommend good ones. A female Genji fanfiction could explore her place in the Overwatch team. For example, it could show how she might interact differently with characters like Tracer or Winston compared to the male Genji. It could also delve into how her gender might change the perception of her by the other characters and the public in the Overwatch lore.
Redemption is a very common theme. Genji has a complex backstory, and many fanfictions explore his journey towards redeeming himself. Another theme is his relationship with his brother Hanzo, either mending it or dealing with the past conflicts.
A crossover with Batman could be fascinating. Batman's detective skills and his arsenal of gadgets could contrast with Genji's more combat - focused skills. They could work together to solve a mystery in Gotham City or in an Overwatch - like city. Genji could learn about stealth and strategy from Batman, while Batman might be impressed with Genji's combat prowess.
A crossover with a cyberpunk - themed story could be really cool. Genji's cybernetic enhancements would fit right in. He could be on a mission in a dystopian city, facing off against powerful corporations and their enforcers. Along the way, he might meet new allies who are also fighting for justice in this harsh environment.
One common theme is redemption. Hanzo, who has a lot of guilt for what he did to Genji in the past, often goes through a journey of redemption in these fanfictions. Another theme is family reconciliation, as they are brothers.
One common theme is the idea of redemption. Genji, with his past full of mistakes and seeking to atone, and Tracer, who represents hope and a positive future, can often be part of a story where Genji finds more redemption through his relationship with Tracer.
Genji was once a carefree playboy from a powerful family in Japan. But his life changed when his family's criminal empire led to a confrontation with his brother, Hanzo. Hanzo was ordered to kill Genji, which he did, but Genji was saved by Overwatch and turned into a cyborg ninja. He then had to come to terms with his new form and find a new purpose in life, which he eventually did by joining Overwatch to fight for good.
The 'enemies - to - lovers' trope is also popular. Maybe they start off as rivals on the battlefield in the Overwatch universe but gradually develop feelings for each other. For example, they could be from different factions initially and then overcome their differences. It adds a lot of drama and tension to the story.
