Maybe the OC has a secret mission that the Teen Titans gradually discover as they get closer to the OC, adding an element of mystery.
The female OC could be a healer. Raven often gets injured during battles, and the OC uses her healing powers on Raven. This creates a connection between them. Eventually, they start to explore each other's pasts and find that they have more in common than they thought.
The male OC should have a distinct backstory. Maybe he grew up in a family of thieves but always wanted to do good. This backstory can influence his actions and decisions in the story. For the Teen Titans, their insecurities can be explored in relation to the harem situation.
