A great place to start looking for such fanfictions is on popular fanfiction websites. You might come across stories that blend the unique elements of both universes. Maybe Harry Potter characters gain some of Saitama's strength, or vice versa. It can be a really fun exploration of two very different fictional worlds colliding.
One idea could be that Saitama somehow ends up in the wizarding world. Maybe he's there to find a new challenge among the powerful wizards. Another could be that Harry Potter discovers the power of One Punch Man's training regime and tries to incorporate it into his own combat skills at Hogwarts. Or perhaps Voldemort makes a deal with an otherworldly being from One Punch Man's universe to gain more power.
Moreover, fanfiction gives fans a chance to contribute to the universes they love. They can expand on existing storylines, fill in gaps, or create entirely new adventures. In the case of Harry Potter and One Punch Man crossovers, it's like opening a door to a whole new world of possibilities, where the magic of Hogwarts and the punches of Saitama can co - exist and create unique and engaging stories.
One common theme could be the exploration of the dark side of magic. In these fanfictions, the torture scenes might be used to show the true evil of certain dark wizards or witches. For example, they could depict how Voldemort's followers might torture their enemies in creative and cruel ways. Another theme could be the strength and resilience of the characters. Through enduring torture, the characters show their unwavering spirit and determination to fight against the dark forces.
Picture this: Hermione and Ron are on the shores of the Black Lake. The sun is setting, casting a warm orange glow over the water. Ron has arranged for a small orchestra of house - elves (who he's befriended over the years) to play a soft, romantic tune. He takes Hermione's hand and leads her to a spot where he has spelled out 'Marry Me' in floating candles. He then pulls out a ring with a small ruby, Hermione's favorite gem. 'Hermione, you're the smartest, bravest woman I know. I can't imagine my life without you. Will you marry me?' Hermione, overcome with emotion, says yes.
Use body language. Harry could be standing tense, his hands clenched into fists while he squints. This shows his determination. And for Voldemort, you can describe his reaction to being stared at in such a way. Maybe he sneers or his red eyes flash with anger. 'As Harry squinted, Voldemort's lips curled into a cruel sneer, his eyes flaring.' This creates a dynamic between them.
A misunderstanding. Harry might say or do something that Ginny misinterprets. For instance, if he makes a comment about her Quidditch skills in a way she thinks is condescending. So, she punches him to show her displeasure. And then the story could unfold as they clear up the misunderstanding.
Harry Potter himself would be an interesting character to crossover into the One Punch Man universe. He would be completely out of his element in a world full of superheroes and monsters. His magic skills would be a new and strange power there. He could team up with Saitama and learn about a different kind of heroism. Also, his experiences with fighting Voldemort could give him unique insights when dealing with the villains in One Punch Man's world.
They often show the victims becoming stronger. For example, if Harry Potter is the victim, he might come out of the torture with a newfound determination to defeat the dark side. His experiences could make him more cautious and strategic in his battles.
