Both Sonic and Percival grow as individuals and as a couple in these fanfictions.
There are various Sonic and Percival married fanfictions out there. Some focus on their daily life as a married couple.

They might also face challenges from the outside world, like dealing with villains who target their relationship.

Power dynamics can also be a theme. For example, if the OC has some special power or ability, how they interact with Graves, who is often in a position of authority. There could be themes of cooperation, rivalry, or even the OC having to prove themselves to Graves. Additionally, mystery-solving related to Graves' past or the events in the story's universe can be a common theme.
Another theme is the exploration of the gray area between good and evil. Graves is often seen as on the side of order, while Grindelwald is chaos. But in fanfiction, their relationship blurs these lines as they interact and influence each other.
