What could be the plot of a fanfiction where Harry Potter helps The Hulk?

In this fanfiction, perhaps there is a disease spreading among the centaurs. Harry Potter, having studied some advanced potions, offers to help. He spends time in the centaur community, brewing potions and using his knowledge of magic to heal the sick centaurs. Along the way, he learns more about centaur culture and they come to respect him greatly.

Well, it could be that Harry Potter somehow gets the powers of the Hulk. Maybe a spell gone wrong during a Defense Against the Dark Arts class that combines his magic with some strange gamma - ray - like magic, and he starts to transform into a green - skinned, super - strong being. He then has to deal with both the wizarding world's problems and his newfound Hulk - like powers.

One possible plot could be that Superman is somehow transported to the wizarding world. He's lost his powers there, and Harry Potter has to help him get back to his own world while also protecting him from the various magical threats in the wizarding world. Along the way, Harry could teach Superman some basic magic to help him defend himself, and Superman could use his strength and heroism in a different way within the magical setting.

The goblin might be helping Harry because Harry once did a favor for the goblin's family. In the fanfiction, the goblin could be an expert in ancient magic spells that have been long forgotten. He could teach Harry these spells, which would give Harry an edge in the fight against the forces of evil. For example, a spell that can turn the dark wizard's own magic back on them.

It could be that the goblins are facing a threat from dark wizards, and Harry steps in to help. He might teach them some defensive magic techniques that humans use, and together they form a plan to fight off the dark wizards. Harry's fame and experience could give the goblins the confidence they need to face their enemies.

Well, it could be that Harry, maybe from the Harry Potter world, accidentally gets transported to the Marvel universe where he meets the Hulk. They might start off as enemies because the Hulk is confused by this strange new person. But then, as Harry shows his magic skills, the Hulk becomes intrigued. And they end up teaming up to fight a common enemy that is threatening both their worlds.

One reason could be a misunderstanding. Maybe some villain has tricked Hulk into believing Spiderman is a threat. For example, the villain might have faked some evidence to make it seem like Spiderman was planning something bad against Hulk or his friends.

One possible plot could be that Aunt Marge discovers Harry's difficult situation at the Dursleys and decides to secretly help him with his magic studies. Maybe she has a change of heart after seeing how much he's struggling.

One possible plot could be that Harry's insanity is caused by a cursed object. His friends then have to find a way to break the curse while also dealing with his erratic behavior. For example, Harry might accidentally reveal secrets to the wrong people because of his insanity.

The plot could involve Harry struggling to hide his true nature as a Nathrezim from his friends at Hogwarts. He might have new, dark powers that he has to learn to control, and he's afraid of how others will react if they find out. Meanwhile, Voldemort senses something different about Harry and is both intrigued and threatened by him.
