I think 'Harry Potter Son of Starfire' fanfiction could be about a completely new adventure. Since Starfire is from a different fictional realm, if Harry is her son, he might be caught between two very different worlds. He could be using his Hogwarts magic along with any special abilities he got from Starfire to fight new enemies or solve problems that neither world has faced before.

One plot twist could be that Harry's vampiric side gives him an unexpected advantage in fighting Voldemort. Maybe he can use his vampire speed to dodge curses better.
