The storyline could involve Harry Potter, now as Goku Black, entering the Dragon Ball universe. He could meet the Z - fighters and they would be both confused and intrigued by this strange new being. Harry might have to prove himself not to be a threat, all while dealing with his own internal conflict of having this new, more aggressive form. He could also bring some of his Hogwarts friends with him, like Hermione, who could try to find a way to reverse the transformation using her vast knowledge of magic.
Well, one possibility could be that Harry Potter, through some sort of magical accident or powerful spell, gets transformed into Goku Black. He might then use his newfound Saiyan powers along with his wizarding knowledge. For example, he could use magic to enhance his ki blasts or use ki to perform spells in a more powerful way. He might also struggle with the evil tendencies of Goku Black while trying to hold on to his own moral compass as Harry Potter.
His magic might become more physical. Instead of just waving a wand, he could use ki to direct spells. For example, his Patronus charm could be charged with ki energy, making it stronger and more tangible. Maybe his spells would be instant like Goku Black's attacks, no need for long incantations.
It could be a really wild and interesting story. Maybe Goku Black could end up at Hogwarts somehow. He might use his power to either cause chaos or try to take over the wizarding world. And the wizards would have to use their magic in ways they've never thought of to fight him.
If Harry Potter becomes Lord Slytherin, he might bring about a new era of unity in Hogwarts. Since he has friends from different houses, he could bridge the gap between Slytherin and the other houses. He may introduce new rules or traditions within the Slytherin house that are more inclusive. For example, he could encourage more cooperation in Quidditch matches instead of the cut - throat competition that has been the norm. Also, his magical abilities, which are already quite remarkable, could be enhanced or used in different ways as Lord Slytherin, perhaps leading to new spells or ways of magic being discovered.
First, you need to figure out how to bring the two universes together. Decide on a way for Goku Black to enter the Harry Potter world, like a magical portal or some kind of interdimensional rift. Then, think about how the characters will react to each other. Harry and his friends will be very different from the characters Goku Black is used to. You should also consider the power levels. Goku Black is extremely powerful, so how will the wizards' magic compare? You can start with a simple plot idea, like Goku Black being lost in the wizarding world and needing help to get back home.
It might be a story where Harry Potter, while exploring different magical texts or spells, stumbles upon a connection to the world of Goku. He starts to study Goku's fighting techniques and tries to incorporate them into his dueling skills.

And he would be constantly in awe of Goku's ability to overcome seemingly impossible odds.
Well, if Harry Potter becomes a Power Ranger fan, the story could change in many ways. Maybe he starts to incorporate some of the Power Ranger's fighting styles into his duels at Hogwarts. He might even dream of having Ranger powers to fight Voldemort.
The storyline could start with a strange magical accident that creates a portal between the Harry Potter universe and the Marvel universe where Black Widow exists.

It could also change his view on magic and how to use it for good in a more action - oriented way.
