Romance is, of course, a very popular theme. Writers often explore the potential romantic relationship between Reinhardt and Ana. This could involve slow - burn romances where they gradually realize their feelings for each other, or stories where they are already in love but face various obstacles, like their duties in Overwatch or the age difference between them.
A theme of redemption can also be found. They both have pasts that are filled with both glory and regret in the Overwatch universe. So, some fanfictions might focus on how they help each other find redemption or come to terms with their past actions. For example, Ana might help Reinhardt deal with his past failures, or Reinhardt could be the one to encourage Ana to face her demons.
One popular theme is their past relationship. Since they have a long history together in the Overwatch universe, fanfictions often explore their shared memories and how their relationship has evolved over time.
One great Ana x Reinhardt fanfic could be 'The Bond of Old Friends'. It delves into their shared history and how they rely on each other in battle. Another might be 'Ana's Watchful Eye on Reinhardt' which focuses on Ana protecting Reinhardt during a tough mission. And 'Reinhardt and Ana: A Reunion' is also good, it shows their reunion after a long time apart and how their feelings have evolved.
