Friendship is also a big theme. These OCs usually form bonds with Harry Potter and his friends. Their friendships are often tested by the OC's family background. For instance, Harry and his friends might be initially suspicious of the Black OC because of the family's reputation, but as they get to know the OC better, they realize they are more than just their family name and form strong friendships. This theme of overcoming prejudice through friendship is quite common in such fanfictions.
Love and Romance are very common. Since it's about Sirius Black and an OC, the development of their relationship, from the first meeting to falling in love, is often a central theme.

First, give them a unique backstory. Maybe they come from a family that was wrongly accused of dark magic in the past. This will shape their personality and motives. Second, develop their appearance.
