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

In the fanfiction, Harry would interact with a sense of camaraderie. He would be one of them in the fight against whatever threat they faced. He would communicate with them, understand their concerns, and work together with them. For instance, if they needed to build a magical defense, Harry would be right there with the centaurs, using his magic wand and following their instructions for the overall plan.

One possible plot could be that Harry Potter uses his magic to help The Hulk gain better control over his anger. Maybe he could use a spell to create a calming aura around The Hulk whenever he starts to get angry. This would allow The Hulk to think more clearly and not go on a destructive rampage all the time.

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.

They can also be mentors. They have a great deal of knowledge about magic, nature, and the stars. In fanfiction, a centaur could take a young wizard or witch under their wing, teaching them things that they wouldn't learn in Hogwarts. This could include ancient spells or ways of communicating with nature. Moreover, centaurs can act as protectors. If there's a threat to the Forbidden Forest or Hogwarts, they might step in to defend it, using their strength and archery skills.

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.

They can also be sources of prophecy or knowledge. Just like in the original books where centaurs have a certain understanding of the stars and future events. In fanfic, they could provide crucial information to Harry or other characters. For example, a centaur might tell Harry about a hidden danger that is related to an ancient magic, which then drives the plot forward as Harry and his friends try to figure out how to deal with it.

The Forbidden Forest is also a big theme. Since centaurs live there, fanfics use it as a backdrop for many stories. It could be about the secrets hidden in the forest that only the centaurs know, or the adventures that happen when a Hogwarts student ventures too deep into the forest and encounters the centaurs. It adds an element of danger and discovery to the stories.

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.
