A really interesting plot can be where Harry discovers the truth about the WBWL situation much later. By that time, he has already started on a dark path. He then has to decide whether to continue down that road or try to redeem himself. This internal struggle between his dark - influenced self and the remnants of his original, more heroic nature can make for a very engaging story.
In some WBWL fanfictions, Harry is ostracized by the wizarding world because they believe he's not the 'true' savior. This makes him turn dark. He might form an alliance with Voldemort's followers out of spite. The plots often explore how his personality changes. He could become more ruthless and calculating, using his natural magical talent in ways that are more self - serving rather than for the greater good.
One interesting plot could be Harry Potter using his intelligence to outwit the Dark Lord in a completely different way than in the original series. For example, instead of relying on pure magic power, he uses his knowledge of magical history and lore to find the Dark Lord's weaknesses. Another plot might involve the Dark Lord having a more complex and intelligent personality, making his actions less predictable and more thought - out. This could lead to a more cat - and - mouse - like battle between Harry and him, with both sides constantly strategizing.
One plot could be that in a dark version, Harry and Luna team up to expose a hidden, evil regime within the wizarding world that has been secretly controlling things from the shadows. They might have to use some rather unorthodox and darker magic to do so.
One plot could be that in a dark world, Harry Potter is influenced by dark magic and Tonks, with her Metamorphmagus abilities, tries to spy on him for the Order but gets caught in his web of newfound power. She has to then fight her own feelings as she was once his ally.
The plot where Murtagh teaches Harry some of his unique magic techniques is really cool. It shows how different magical systems can interact. For example, in a fanfic I read, Murtagh showed Harry how to use a spell that was common in his world but unheard of in Hogwarts.
In 'The Mysterious Bond between Harry and Grindelwald', the plot focuses on a strange, unspoken bond that seems to exist between the two. This bond affects their decisions and actions throughout the story. It's a unique take on their relationship and makes for a very engaging read.
Well, in some fanfics, like 'The Darker Side of Redemption', Lucius is given a chance at redemption after the fall of Voldemort. Harry plays a key role in this process, either by being a reluctant helper or an unexpected friend. The plot often involves exploring the darker parts of the wizarding world that were not fully shown in the original books.
One interesting plot could be Harry using his magical skills in veterinary work. For example, he might use spells to heal injured animals quickly. Maybe he'd have to deal with magical creatures that are acting strange and he has to figure out if it's a magical illness or something else.
Well, there's a plot where Penelope is secretly a powerful witch with ancient magic in her bloodline. In this fanfic, she has to hide her true power from everyone at Hogwarts. It makes for a really exciting read as she tries to balance her normal school life with the secrets she's keeping.
Another interesting plot is when they both become involved in a secret society within the wizarding world that is trying to bridge the gap between wizards and Muggles. Draco brings his knowledge of the wizarding elite and Dudley his understanding of the Muggle world. Their partnership in this fanfic is full of twists and turns as they face opposition from both sides of the divide.
Some fanfics might explore Nagini's connection to the other Horcruxes. Since she was the last Horcrux to be destroyed, perhaps there was some kind of communication or power exchange between her and the other Horcruxes that we didn't see in the books. This could add a whole new layer of mystery to the story.
