There's this fanfic called 'A New Alliance'. It's not just about the relationship between Hanzo and McCree but also about how they team up to face challenges in the Overwatch world. The way the author writes their interactions is quite engaging.
One common theme is the family aspect. Since Ana is Pharah's mother, some fanfics explore their relationship from a more emotional and family - bond perspective. They might deal with issues like Ana coming back into Pharah's life after being absent for a while.
One common theme is friendship. They often start as friends or comrades and their bond grows deeper. Another theme is mutual support. They help each other out in battles and in personal issues. For example, Mercy might heal Pharah during a tough fight, and Pharah might protect Mercy from enemies.
Another theme is loyalty. In many fanfics, they show loyalty to each other and to their cause in the Overwatch world. This loyalty often strengthens their relationship.
A common theme is the clash and then the melding of their cultures. Brigitte comes from a more traditional, family - based background in Overwatch lore, while Pharah has a military - influenced upbringing. Their fanfictions often explore how they bridge this gap.
Protection is also a major theme. McCree feels the need to protect Mercy from the dangers of the world they live in, while Mercy protects McCree in her own way, by healing his physical and sometimes emotional wounds.
One common theme is redemption. Hanzo often has a past he's trying to atone for, and mccree can be a part of that journey. For example, in many fanfics, mccree helps Hanzo see that he can move forward from his past mistakes.
Another theme is the contrast between their personalities. Genji is more of a reserved, yet spiritually - inclined character, while McCree is more of a rough - around - the - edges cowboy type. Fanfictions often play on this contrast, showing how they complement each other and learn from one another as their relationship progresses.
There's also 'Under the Stars'. This one is more of a slow - burn type of fanfiction. It delves deep into the feelings of the male reader towards McCree. The author does an amazing job of describing the settings and the internal struggles of the characters, making it a very immersive read.
The plot is key. It could be something as simple as them getting to know each other better during a mission or a more complex story about their pasts affecting their relationship. Also, the chemistry between them has to be believable. If it feels forced, the fanfic won't be good.
