In this fanfiction, perhaps there's a crossover of their skills. Harry Potter could use his magic to enhance John Wick's weapons. For example, making his bullets have magical properties like tracking spells. John Wick could teach Harry Potter how to be more stealthy and efficient in combat without relying solely on magic. The story could be set in a post - Voldemort world where a new danger emerges, and they have to combine their strengths to save both the wizarding world and the normal world that John Wick comes from.
Maybe in the fanfiction, the Avengers need someone with John Wick's particular set of skills for a stealth mission. John Wick initially refuses but is later convinced when he realizes the threat is global. During the mission, they learn from each other's combat styles and strategies, and John Wick's no - nonsense attitude impresses the Avengers.
Maybe John Wick gets transported into the Harry Potter universe. He could be mistaken for a dark wizard at first because of his menacing appearance and combat skills. But then he teams up with Harry and his friends to fight against Voldemort's remaining followers who are using new, more brutal tactics. The fanfic could show how John Wick's no - nonsense attitude and fighting style influence the way the Hogwarts students approach battles.
Well, it could be a wild and wacky adventure. Picture Deadpool popping into Hogwarts, causing chaos with his fourth - wall - breaking antics while the Hogwarts students are trying to study magic. He might make fun of Snape's greasy hair or try to steal Harry's invisibility cloak for some 'fun' missions. And Harry, with his sense of justice, would be constantly trying to keep Deadpool in line.
In this fanfiction, perhaps there's a spell gone wrong that transports Harry and his friends to a prehistoric world full of velociraptors. They have to use their magic skills to survive in this new environment. Harry might use his Patronus charm to fend off the raptors at first, but then they gradually learn to communicate with the raptors using some kind of translation spell and together they try to find a way back to their own time.
Well, in a Harry Potter - Rasputin fanfiction, Rasputin could be reimagined as a character with unique powers. For example, his supposed ability to heal in real life could be translated into some sort of magical healing ability in the fanfic. But he could also have a dark side, perhaps being influenced by the Dark Arts. He could interact with Harry and his friends, either as an ally or an enemy, depending on the plot. And his presence could disrupt the normal balance of power at Hogwarts.
It could be really interesting. Maybe it would involve Harry Potter characters in the strange and often dark world of Eraserhead. For example, Harry could find himself in a situation similar to the disturbing environments in Eraserhead, facing challenges that are not just magical but also of a psychological nature.
Well, in such a fanfiction, the characters from Harry Potter would be in for a shock. Yharnam is a very different and dangerous place compared to Hogwarts. Harry, Hermione, and Ron could find themselves facing challenges that require not just their magical knowledge but also a new level of courage. They might meet some of the hunters in Yharnam and learn about their ways of fighting. And perhaps, they could introduce some new magical concepts to the people of Yharnam, like the use of potions for different purposes than just healing.
Well, it could be that Mjolnir has been lost in the wizarding world for centuries. Harry, Ron, and Hermione find it during one of their adventures. Ron tries to lift it first but fails. Harry then approaches it, and as he touches it, a surge of power runs through him. This new power allows him to see things in a different way. He can now sense the presence of Horcruxes more easily and also has the strength to break through some of Voldemort's most powerful defenses. The story could revolve around how they use Mjolnir's power in their fight against the Dark Lord without causing too much disruption in the magical balance.
In a Harry Potter - Hawkeye fanfiction, Hawkeye might be mistaken for a new kind of wizard. He could befriend Harry and his friends. Hawkeye could teach them about non - magical combat skills, while they introduce him to spells and potions. It would be interesting to see how his modern - day weapons and combat knowledge interact with the magical elements of the Potterverse.
It could be really interesting. Maybe the characters from Harry Potter could somehow enter the world of Eyeshield 21. For example, Harry could use his broomstick skills to play American football in the Eyeshield 21 universe. Or Hermione could use her intelligence to come up with new strategies for the football teams.
