One common trope is the 'protective big brother' role. For example, a character might act like a big brother to Harry, shielding him from bullies at Hogwarts. Another is the 'wise big brother' who imparts magical knowledge or life lessons. In some fanfics, a character could be a big brother figure to Hermione, guiding her through difficult social situations at school. There are also 'troubled big brother' tropes where the character has a dark past but still tries to look out for others in the wizarding world.
Often, there's the 'mysterious big brother' trope in Harry Potter fanfics. This character might have a hidden past or special powers that they gradually reveal while looking out for someone. The 'big brother in disguise' is another. A character could be undercover, pretending to be just an ordinary student but actually on a mission to protect someone important. And then there's the 'big brother with a secret agenda'. He may seem helpful on the surface but has ulterior motives related to the overarching plot of the fanfic, like uncovering a dark wizard's plan.
A frequently seen trope is the 'big brother as a mentor'. This can be a character who has been at Hogwarts longer and takes a younger student under their wing. They might help with spellcasting or understanding the complex rules of the wizarding world. Also, the 'big - hearted big brother' is popular. Such a character shows great empathy and is always there to comfort those in distress, like when a first - year student is homesick. Sometimes, there's the 'rival - turned - big - brother' trope, where a character who initially competed with another later becomes a protective figure.
One common trope is the 'hidden power' trope. In many fanfics, a character, often a new or overlooked one, discovers they have a powerful and previously unknown magical ability. For example, a Hufflepuff student might find out they can control time in a way not seen before in the wizarding world. Another is the 'alternate universe' trope where the story is set in a completely different version of the Harry Potter universe, like a world where Voldemort won the war and the characters have to deal with the consequences. The 'teacher - student relationship' trope is also popular, where a deeper bond forms between a student and a teacher beyond the normal classroom dynamic, like a special mentoring relationship between Harry and a new, young teacher.
One common trope is the 'knowledge advantage'. Since the character is reincarnated as Harry Potter, they often use their prior knowledge of the wizarding world's events to their advantage. For example, they might know about Voldemort's plans in advance and take steps to prevent them. Another trope is 'relationship changes'. They might interact differently with characters like Hermione and Ron, perhaps forming closer bonds or different types of relationships altogether. And then there's the 'power boost' trope. The reincarnated Harry often gains new magical abilities or is able to master existing ones more quickly due to their past experiences.
One common trope is the 'forbidden crush'. For example, a Gryffindor having a crush on a Slytherin, which goes against the house rivalries in Hogwarts. It adds tension and drama to the story.
One common trope is the 'alternate universe' where the story takes place in a different setting than the original books. For example, a modern-day muggle world with hidden wizarding elements. Another is the 'character redemption' trope, like Draco Malfoy being redeemed and becoming friends with Harry. And the 'power - up' trope is also seen, where a character discovers new and greater magical abilities.
Fred and George Weasley are also excellent big brother - like characters in fanfics. They are fun - loving and mischievous, but they also have a strong sense of family and would do anything to protect their younger siblings or friends who they see as family. They can introduce a lot of humor and light - heartedness into the story while still being there for the important moments. In some fanfics, Neville Longbottom can also be portrayed as a big brother. He grows so much throughout the series and can offer support and stability to other characters.
Well, a typical trope is the main character having special abilities due to their reincarnation. This could be something like enhanced magic skills or the ability to understand ancient magic more easily. For instance, they might be able to cast spells without a wand more effectively than others. Another common thing is that they often have a different perspective on the Hogwarts houses. Instead of the usual biases, they might see the value in all houses and try to bridge the gaps between them. And, of course, there's the trope of falling in love with a character in a different way than in the original story. Maybe the reincarnated character ends up with someone who was just a minor character in the original.
One common trope is the 'outsider becomes central' where the main character, often an original character in the fanfic, is suddenly in the middle of a group of Hogwarts students who form a sort of harem. For example, a new student from a different magical school might come to Hogwarts and attract the attention of Harry, Ron, Hermione and others in a romantic or platonic way that builds a harem - like dynamic.
Well, a TV Trope often seen in Harry Potter fanfic is the 'Redemption Arc'. For example, a character like Draco Malfoy might have a more in - depth redemption arc in fanfic than in the books. The 'Love Triangle' trope is also popular. It could be between Harry, Hermione and Ron in a different way than in the original, or it could involve new characters. And then there's the 'Secret Identity' trope. A character might be hiding a big secret about their true nature or abilities, which adds an element of mystery to the fanfic.
One common TV Trope in Harry Potter fanfic is the 'Character Growth' trope. Many fanfics focus on how minor characters from the original series develop and change. For example, Neville Longbottom is often given more in - depth development, showing his journey from a shy and clumsy student to a powerful wizard. Another trope is 'Alternate Universe'. Fanfic writers like to explore what would happen if certain events in the Harry Potter universe were different. For instance, if Voldemort had never existed, how would the wizarding world be different? And the 'Shipping' trope is also popular. Writers create relationships between different characters, like Hermione and Draco, which were not canon in the original books but make for interesting reading in fanfic.
One popular trope is the 'fish out of water' story. For instance, a superhero is suddenly dropped into the wizarding world and has to figure out how to use magic or just deal with the strange customs. Another is the power - sharing trope. Maybe a wizard shares their magic with a superhero, or vice versa, creating a new and powerful combination.
