In Harry Potter fanfic, elves are often portrayed in diverse ways. Some fanfics might expand on the house - elves like Dobby and Winky. They could be given more complex personalities, for example, an elf who is not only subservient but also has dreams of freedom and education. Some might show elves with magical abilities beyond what was shown in the original books, like the ability to transform into other creatures momentarily to escape danger.
In Harry Potter fanfic, monsters can be portrayed in various ways. Some are depicted as fearsome and menacing, like the traditional view of a werewolf during a full moon. They might be used to create suspense and danger in the story. For example, a basilisk could be lurking in the depths of Hogwarts, ready to petrify anyone who looks into its eyes.
Often, famine in Harry Potter fanfic can be a backdrop to show the social and economic disparities within the wizarding world. Some fanfic authors may depict poorer wizarding families or those on the outskirts of society suffering from famine while the wealthy or those closer to the Ministry seem unaffected. It could also be a factor in driving characters to make desperate choices, like joining a dark cause in exchange for food for their families.
In some Harry Potter fanfics, seduction might be portrayed through the use of magic. For example, a character could use a charm to make themselves more alluring. However, it's important to note that this often goes against the more innocent nature of the original series. Fanfic authors sometimes take creative liberties, but it can be a controversial topic among fans.
In fanfic, the Nundu is often portrayed as a huge, hulking beast with a menacing presence. It's shown as very powerful and its poisonous breath is usually emphasized.
It's often portrayed as a very alluring potion. In many fanfics, the description of its smell is really detailed. For instance, one character might smell freshly baked cookies (if they have a thing for food or a baker they like) and a particular type of flower that grows in a place special to them.
In some Harry Potter fanfic, incendio is portrayed as a very powerful spell. It can quickly create large and intense fires that are hard to control. For example, a character might struggle to contain the fire they've created with incendio.
In the world of Harry Potter fanfic, sex is not a common or appropriate topic. The source material is centered around the wizarding world, with its unique creatures, spells, and a story of a young wizard's journey. Fanfic writers should be more interested in things like how the wizarding education system could be improved in their stories, or how the characters would react to new magical threats. Sexual content just doesn't fit into this magical universe that J.K. Rowling created for all of us to enjoy as a story of magic, not adult themes.
Ghosts can also be portrayed as tragic figures. Take Moaning Myrtle for instance. Fanfic might expand on her sad story, showing how her death and her state as a ghost are a result of her unfulfilled desires and the pain she endured while alive. They can add a touch of melancholy to the story.
Gluttony could also be depicted in a more symbolic way. A character might be 'gluttonous' for power or knowledge within the wizarding world. They constantly seek more spells, more magical artifacts, without any regard for the consequences. In fanfics, this could be a villainous trait, like a dark wizard who wants to hoard all the powerful magic for himself.
In many Harry Potter fanfics, isolation can be portrayed in various ways. For example, a character might be isolated due to being a pariah in Hogwarts because of a new or misunderstood magical ability. This could lead to them having to find their own place in the wizarding world outside the norms of the school. Another way is through a character being ostracized for their family's actions, like if their family has ties to the Death Eaters. They may face isolation from other students who fear or distrust them.
