Another plot device is how Harry uses his super strength to face new challenges. This might include fighting off a new breed of dark wizards or protecting Hogwarts from a different kind of danger. In many fanfictions, his super strength makes him a target as well, so there's often a plot about him being hunted. In one particular fanfic, his super strength led to him being framed for a crime he didn't commit because the real villains were afraid of his power.
One common plot device is the introduction of new characters who initially misunderstand Harry, which makes him feel more alone. For example, a new student might come to Hogwarts and, because of rumors or Harry's fame, avoid him or be unkind, adding to his sense of isolation. Another device could be the separation from his friends. Maybe there's a magical accident that sends Harry to a different dimension or a locked part of the castle where he's completely alone and has to figure out how to get back while feeling lonely and scared.
Super strength can change the plot by making battles easier for the character with the power. For example, if Harry has super strength, he can quickly defeat Death Eaters in physical combat, which might shorten the length of the war in the wizarding world. This changes the overall pacing and outcome of the story.
One common plot device is the discovery of ancient artifacts or prophecies that link Harry to Merlin. For example, a magical amulet that was once Merlin's might be found and react only to Harry. Another is the appearance of a character who knew Merlin in the past and recognizes Harry as his reincarnation.
The use of prophecies is also quite common. Similar to how there are prophecies in both Harry Potter and Game of Thrones, fanfictions might create new prophecies that involve characters from both worlds. For example, a prophecy about a character from Game of Thrones being the key to defeating Voldemort. This creates a sense of destiny and drives the plot forward. Also, the idea of hidden identities can be used, like a character from Harry Potter disguising themselves as a noble in Westeros and causing all sorts of chaos as their true nature and abilities are gradually revealed.
One common plot device is Fem Merlin being a time - traveler. She could come from the past or future to change certain events in the Harry Potter timeline. This can create a lot of interesting scenarios where she has to adapt to the modern wizarding world while also trying to achieve her mission.
A common plot device is the exploration of a hidden magical world related to Merlin. Harry, as the heir, is the key to unlocking this world. There might be new magical creatures, spells, and challenges there. He could also face opposition from those who fear his new power or those who want to use him for their own evil purposes. This creates conflict and tension in the story. Additionally, his connection to Merlin could lead to a rewriting of history or a new understanding of the origins of magic in the wizarding world.
Often, in these fanfictions, the discovery of a new, ancient and dark magic artifact can be a plot device. Harry might find this artifact and, as he tries to understand or control it, he starts to develop dark powers. Also, the idea of a prophecy misinterpreted can play a role. A prophecy that was thought to be about his heroism is actually about his fall to the dark side, leading him to explore and use dark powers.
One common plot device is the discovery of her royal lineage. It usually happens in a dramatic way, like finding a hidden letter or a magical object that reveals her true identity. Another is the conflict between her wizarding life and her new royal duties. She has to balance things like going to Hogwarts and attending royal functions. Also, there's often a love interest from the royal court, which creates a love triangle with her existing relationships in the wizarding world.
One common plot device is the revelation of hidden powers. When a blood binding is involved, often characters discover new and unexpected magical abilities that are tied to the bond. For example, they might be able to communicate telepathically or share magic in unique ways.
A common plot device is misdirection. Harry might create a false lead or distraction that makes Snape focus on the wrong thing. For example, he could stage a minor 'accident' in the corridor that draws Snape's attention while he slips away to do something else he's not supposed to. Another device is using his friends' unique abilities. If Hermione has found a loophole in a rule, Harry can use that knowledge to outmaneuver Snape who is always strict about the rules.
