In some fanfictions, the crossover might involve Nightwing getting a magical ability. This could change the dynamics of his crime - fighting in Gotham. He could use spells to enhance his combat, like a levitation spell to gain an advantage in a fight. At the same time, he could teach Harry and his friends some self - defense techniques from the muggle world. This exchange of skills between the two different universes can create a unique and engaging story.
A really cool storyline would be if there was a magical artifact in Gotham that was connected to the wizarding world, and Nightwing and Harry team up to retrieve it. Nightwing's acrobatic skills and knowledge of the city streets combined with Harry's magic would make for an exciting adventure. They could face off against both magical and non - magical foes along the way. Maybe the artifact is being sought by Voldemort and one of Gotham's super - villains, so they have to work together to stop it from falling into the wrong hands.
Perhaps a story where Loki steals a powerful magical artifact from Hogwarts. The Avengers team up with Harry, Hermione, and Ron to get it back. Hermione's knowledge of magic combined with Tony Stark's intelligence could lead to some really cool problem - solving. And the action scenes would be amazing, like when Hulk goes on a rampage through the Forbidden Forest while the wizards try to calm him down.
The storylines involving his relationships, like with Barbara Gordon, are quite engaging. Their complex dynamic, from being friends to having romantic feelings at times, adds depth to the Nightwing comics. It shows a different side of Nightwing, not just as a crime - fighter but also as a person with emotions.
Bellatrix Lestrange and Nightwing would be an unexpected duo. Bellatrix is a deranged Death Eater, and Nightwing is a symbol of good in Gotham. But if Voldemort made a deal with a Gotham super - villain to take over both worlds, and Bellatrix was sent to work with Nightwing as part of the deal, they would have to find a way to coexist, at least temporarily. Their interactions would be full of tension and power struggles.
A really cool storyline could be where Doctor Strange opens a portal to the wizarding world by accident. The Avengers then find themselves in Hogwarts. They are initially confused but soon realize they need to work together with the wizards. For example, Hulk could befriend Hagrid and help him with some of his more dangerous magical creatures. And Black Widow could train some of the Hogwarts students in combat skills, while the wizards teach the Avengers some basic defensive spells.
One interesting storyline could be the Winx Club fairies visiting Hogwarts. They could share their magic with the Hogwarts students, like Bloom showing how to control powerful dragon - like magic. Another could be a joint battle against a common dark force that threatens both the magical realms of Winx Club and Harry Potter. For example, Voldemort teaming up with the Trix and the Winx and the Hogwarts students having to combine their different magical skills to defeat them.
One possible storyline could be that the members of One Direction are secretly wizards attending Hogwarts. They could form a new kind of wizard band within the school, using magic to enhance their music. For example, they might use spells to create amazing light shows during their performances in the Great Hall. Another storyline could be that they are on a mission to help Harry Potter defeat Voldemort in a more modern, musical way. Maybe their music has the power to weaken the dark forces.
One interesting storyline could be a magical item from the Harry Potter world ending up in the Marvel universe. For example, the Time - Turner. This could lead to all sorts of chaos as characters from both universes try to figure out how to use it or keep it from falling into the wrong hands. In the harem aspect, perhaps Hermione finds herself in the middle of a group of Marvel heroes who are all intrigued by her intelligence and magic. Another could be that a spell gone wrong in Hogwarts transports some of the students to the Marvel world. There, they meet the Avengers and other heroes, and some of the students start to form relationships with them, creating a harem - like situation.
In some fanfictions, Andromeda's backstory with the Black family is really fascinating. Her decision to marry a Muggle - born and be disowned by her family sets up a great narrative. She could be shown as having a complex relationship with her sisters Bellatrix and Narcissa. Maybe she tries to redeem Bellatrix at some point or has a hidden understanding with Narcissa. Also, her role in the post - Voldemort wizarding world, like helping to rebuild society and deal with the aftermath of the war, can be a really interesting storyline.
The most interesting element is the clash of different universes. For example, when Harry Potter's world meets the world of Middle - earth from 'The Lord of the Rings'. The magic systems are so different. In Harry Potter, it's about wands and spells, while in Middle - earth, it's more about the power of the rings and the different races like elves and hobbits. Another cool element is seeing familiar characters in new situations. Like Hermione in a world full of superheroes.
The most interesting aspect is the combination of magic systems. The unique jutsu in Naruto and the spells in Harry Potter can create really exciting scenarios. For instance, a wizard using a Patronus charm against a Naruto - style demon. Another aspect is the character interactions. Imagining Naruto and Harry as friends or rivals is very appealing.
