One common theme is friendship. Often, the OC starts as a stranger to Hermione and they gradually become friends, supporting each other through different challenges in the wizarding world. For example, they might face challenges related to schoolwork at Hogwarts or threats from dark wizards.
Another theme is adventure. The OC usually brings some new element into Hermione's life that leads them on an adventure. This could be a search for a lost magical artifact or exploring a new part of the wizarding world that has been hidden for ages. The story then follows their journey filled with excitement and danger.
A third common theme is the exploration of new magical concepts. The OC might introduce Hermione to a different way of using magic or a new magical theory. This not only adds an element of intrigue to the story but also showcases the creativity of the fanfic writer. In many such fanfics, this exploration of new magic becomes a bonding point between Hermione and the OC.
Magic exploration is also a prevalent theme. The oc may introduce new ways of using magic or discover forgotten spells along with Hermione. Additionally, there can be a theme of facing challenges together. Whether it's against dark wizards or school bullies, they support each other.
One common theme is friendship. Since there are three OCs, their relationships with each other often form a big part of the story, like in 'The Trio's Friendship' where they rely on each other through thick and thin.
One common theme is the discovery of new magic. The male oc often brings in some new aspect of magic that Hermione is intrigued by, and they explore it together.
One of the themes is the exploration of their different personalities. Ginny is more outgoing and sporty, while Hermione is bookish and logical. Fanfics play with how these differences can either create friction or lead to a great partnership. Also, the theme of loyalty comes up a lot. They are loyal to their friends and Hogwarts, and this loyalty is often a driving force in the stories.
One common theme is mentorship. Hagrid, being older and more experienced in the magical world, often acts as a mentor to Hermione. For example, he might teach her about the more secretive or dangerous aspects of magical creatures that she wouldn't learn in a classroom.
Friendship or romance developing in an unusual setting is also a common theme. Given that Charlie is in Romania most of the time, the setting is different from Hermione's usual Hogwarts or Ministry - related settings. The fanfics often play with this contrast, showing how they form a bond despite the differences in their worlds, be it a deep friendship or a budding romantic relationship.
