Well, the fan might introduce Tim to a whole new set of values based on the themes in Harry Potter. Such as the importance of friendship like Harry, Ron and Hermione's. Tim could be taught to stand up against bullies just as the characters in Harry Potter do. And perhaps he would be encouraged to be brave and curious, traits highly valued in the wizarding world.
A possible plot could be that the dragon is a shapeshifter and takes on a human form to better raise Tim Drake in the human world. It could teach Tim about his own hidden powers that he didn't know he had. The dragon might also have a nemesis from its own kind, and when that nemesis discovers Tim's existence, they target him, leading to a whole new set of challenges for Tim. This could involve Tim having to discover the secrets of his dragon - raised past to defeat this new threat.
Tim could be more empathetic. Harry Potter has a strong sense of justice and empathy for others. So, if raised by a Harry Potter fan, Tim might develop a similar trait. He would care more about the underdog and be more likely to stand up for those in need. He may also be more open - minded, as the Harry Potter series often promotes acceptance of differences. For example, the different houses in Hogwarts each have their own characteristics, but they all work together in the end. Tim could grow up with this understanding that everyone is different and that's a good thing.
His relationship with the Bat - family would likely be more strained. Since he was raised by a dragon, he might have different values and ways of doing things. For example, he could be more impulsive like a dragon in combat rather than following Batman's strict rules. This would cause friction with Batman and the other Robins who are used to a more controlled approach.
One common theme is the struggle between his human and dragon sides. He might have to keep his dragon nature a secret from his friends and family in the Bat - family. Another theme could be his new - found powers and how he uses them for good or has to control them so as not to cause harm.

Perhaps a plot twist could be that Tim Drake's angel - raised nature makes him an outcast among both humans and angels. The angels see him as too human, while the humans are afraid of his otherworldly upbringing. This could lead to him having to find his own place in the world, and in the process, he uncovers a conspiracy that links the two worlds more closely than anyone thought.
