Along the way, he uncovers secrets about his father's adventures with Stark that were previously unknown.
Well, in fanfiction, anything can happen. It could be that some sort of cosmic entity decided to play a joke and made Tony Stark Harry Potter's father.

Then, through a series of events, it was discovered that he was Harry's father. It's all about creativity and bending the rules of the original universes.
One possible plotline could be that a powerful magical spell in the Harry Potter universe somehow crosses over and affects Tony Stark, causing the mpreg situation.

A possible plotline is that Harry grows up in a world where magic and technology co - exist. He uses his combined heritage to solve mysteries that neither wizards nor superheroes could alone.

His relationships with characters like Hermione and Thor would also be central to the story, as they help him understand his two sides.
Well, there could be a plotline where Snape's father was an inventor in the wizarding world. He might have created some powerful magic items or spells that were lost or forgotten.

There could also be a plotline where Snape's father was a mentor to some other important character, and this connection has implications for Snape's life and the overall story.
