The goblin could be developed by showing his relationship with the goblin society. He might be an outlier in the goblin community, having different beliefs or values. As he helps Harry, he also has to deal with the consequences of going against his own kind in some ways. This internal conflict could shape his character. He could be shown to have a deep love for the magical artifacts in Gringotts, which is part of his identity, but also be willing to risk everything to help Harry, which shows his growth and change throughout the fanfiction.
The goblin could start off as a mysterious figure. For instance, he could first appear to Harry in a dream, giving him cryptic messages. As the story progresses, we learn that he has his own motives, like seeking revenge on a wizard who wronged him in the past. His character could develop from being a bit of an enigma to a fully - fleshed - out ally with a complex backstory.
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.
The Goblin King could interact with Hermione by challenging her intellect. For example, he might present her with a complex riddle related to goblin lore that she has to solve. With Ron, he could have an argument over food or some valuable item that Ron accidentally took from a goblin - owned place. And with Neville, the Goblin King might initially underestimate him but later be impressed by Neville's courage when they face a common threat together.
There could be an entirely new goblin character created just for this fanfiction. This goblin lawyer could be an outcast from the goblin community because of his more progressive views on wizard - goblin relations. Harry, seeing his potential, hires him to help with his legal battles that require a fresh perspective.
Harry's sense of justice would be further emphasized. Saving the goblin child shows that he doesn't discriminate based on species. His confidence would also grow as he overcomes the challenges in saving the child. He would become more respected among the goblin community too.
In many Harry Potter fanfictions, goblins are often portrayed as highly intelligent and skilled beings. They are usually depicted as having a great knowledge of magic, especially when it comes to handling precious metals and objects like Gringotts' treasures. They are often shown to be proud of their heritage and magical abilities, and some fanfictions explore their relationship with wizards in more depth, sometimes highlighting the power dynamics and the goblins' sense of independence.
The relationship could develop through shared interests in magic. The goblin might be fascinated by some of the spells Harry has learned at Hogwarts that are different from goblin magic. They could exchange knowledge, with Harry learning about goblin - made magical items and the goblin learning about human - style spellcasting. This exchange of knowledge would deepen their bond.
Often, they are portrayed as intelligent and cunning. They have a deep understanding of magic, especially in relation to their work with precious metals and magical artifacts. Their loyalty can be a key aspect too. If they become a friend, they will go to great lengths to protect their human friend, like in stories where they fight alongside Harry against Voldemort's forces.
Maybe Harry discovers that the goblins are being wrongly accused of something in the wizarding world, like being framed for a theft in Gringotts. So he decides to use his influence and skills to defend them, showing that not all goblins are bad and that they have been misjudged.
Well, perhaps Harry stumbles upon a goblin in a dangerous situation, like being trapped by dark wizards who want to steal the goblin's magic artifacts. Harry uses his skills and spells to fend off the bad guys and rescue the goblin.
The goblin training could transform Harry into a more street - smart wizard. Goblins have their own set of rules and ways of doing things. Harry would have to adapt to these new ways. This could lead to him being less trusting of traditional wizarding institutions and more likely to question the status quo. His character might become more resourceful as he learns from the goblins' unique skills and knowledge.
