Well, perhaps the plot could involve Harry discovering his Titan heritage and having to deal with new powers. He might struggle to balance his wizarding world life with this new Titan side. Maybe he has to face enemies that are both from the wizarding world and related to his Titan lineage.

Well, one possibility could be that Harry discovers his true parentage as Sauron's son in a very shocking way. Maybe through some dark magic revelation.

In this fanfiction, perhaps Harry's identity as the Joker's son makes him an outcast in the wizarding world.

He may also be drawn into a mystery related to the ancient Greek magic that his father represents, and he has to travel to different places, both in the wizarding world and perhaps even to the remnants of the ancient Greek magical sites, to uncover the truth about his powers and his role in the grand scheme of things.

Well, perhaps Harry could inherit some of Hercules' super strength. He might use it to fight Voldemort in a more physical way, like being able to lift and throw large objects at the Death Eaters.
