One common act of betrayal in this kind of fanfiction could be a magical creature betraying its human allies. For instance, a house - elf that has been mistreated by wizards might decide to help Voldemort in order to get revenge. Or perhaps a centaur, who has always been neutral in the wizarding wars, could be swayed to side with the dark forces due to some wrongdoings of the wizards towards them. This would change the dynamics of the wizarding world and create a more complex and unpredictable story.
Well, in such fanfictions, one key event could be a character who was thought to be a loyal friend turning out to be a Death Eater spy. For example, a character like Seamus Finnigan might be made into a traitor in the fanfic, revealing secrets of the Order of the Phoenix to Voldemort. Another could be a teacher at Hogwarts, who, instead of protecting the students, betrays them to the dark side for power or fear. It really depends on the creativity of the fanfic writer, but often it involves the breaking of trust within the wizarding community.
Peter Pettigrew is a very likely character to be involved in more acts of betrayal in fanfictions. Since he already betrayed James and Lily Potter in the original story, it's easy to imagine him continuing his traitorous ways. Another could be Draco Malfoy. In some fanfictions, he might be made to do more extreme acts of betrayal rather than just being a bully. He could be forced to betray his schoolmates in a more serious way for the sake of his family's safety.
Snape is a likely candidate. In the original series, his loyalties were always a bit of a mystery at first. In fanfiction, he could be further explored in terms of false betrayals or real ones. Another one could be Draco Malfoy. He was on the verge of becoming a full - blown Death Eater in the original, so in fanfiction, he could either truly betray his Hogwarts classmates or be wrongly accused of betrayal.
It could be a fanfiction where the author creates a new plotline centered around an act of betrayal that sets off a series of events. For example, it might be about a wizard who betrays the Order of Phoenix to Voldemort, leading to new challenges for Harry and his friends. The 'Flames' part could symbolize the intensity and the destructive nature of this betrayal, like how a flame can quickly spread and cause chaos.
One interesting idea could be a betrayal within the Order of the Phoenix. Maybe a member is secretly working for Voldemort and revealing the Order's plans. Another could be a betrayal among Hogwarts students, like a best friend turning on another due to jealousy over academic achievements or popularity. It could also be a teacher betraying Dumbledore's trust for personal gain or a darker ideology.
Cedric Diggory could be an unexpected character in a betrayal scenario in fanfiction. Maybe in an alternate version, he becomes jealous of Harry's fame from being in the Triwizard Tournament and betrays him. This could be a really interesting twist as Cedric is generally seen as a good and honorable character in the original story.
One idea could be that a character inherits a powerful but dark magical item which causes others to suspect betrayal. For example, if a minor character inherits a cursed object that was once used by a Death Eater, and suddenly people start to question their loyalty.
One possible plotline could be a friend betraying Harry to gain favor with the Death Eaters. Maybe they leak information about Harry's tasks in the Triwizard Tournament. This would add a whole new layer of danger and drama to the story.
Revenge is also a theme that pops up. After being betrayed, some characters in these fanfics might seek revenge. It adds an extra layer of drama and conflict. Additionally, the theme of redemption can be seen. Sometimes the betrayer realizes their mistake and tries to make amends, which creates a complex and interesting storyline.
One common betrayal in Harry Potter fanfiction is when a supposed ally turns out to be working for Voldemort. For example, a new character who seems friendly to Harry and his friends might be revealed as a Death Eater spy. This adds a lot of drama and twists to the story, making the characters question who they can trust.
Authors use various ways to portray betrayal. They might start with small hints, like a character being evasive in their answers or acting a bit too interested in certain secrets. For example, a character might be constantly asking Harry about the location of the Order of the Phoenix's headquarters in a very sneaky way.
