The idea of soul magic in both worlds is often explored in a really engaging way. In Soul Eater, souls are a central concept, and in Harry Potter, there's the idea of the soul being split or protected. Fanfictions often combine these ideas, like a character's soul being affected by a Horcrux in a way that's related to Soul Eater's soul mechanics. This can lead to some really complex and thought - provoking plotlines that keep readers hooked.
A common interesting plot point is the clash of the two different educational systems. Hogwarts' classes and the DWMA's training are very different, and seeing how characters adapt to this is cool.
The idea of a common enemy is also very appealing. Maybe a powerful demon from Inuyasha's world that is so strong it threatens both worlds, and the characters from both series have to work together. This forces them to overcome their initial misunderstandings and differences. For instance, the Soul Eater crew might not trust Inuyasha at first because of his demon side, but as they face this huge threat, they learn to rely on each other.
A great plot twist could be that one of the main characters from Soul Eater, like Maka, turns out to be related to a wizarding family in the Harry Potter world. Maybe her mother was a witch who fled to the Soul Eater world to escape some dark magic in the Harry Potter world. This would completely change the dynamics of how she interacts with the Harry Potter characters.
Well, perhaps Harry could be a weapon that has the power of his magic from the Potter world. He might be used by a Soul Eater character to fight against evil souls. Maybe his wand could transform into a more weapon - like form in the Soul Eater world.
Well, there are several. The idea of Dexter being exposed to magic for the first time can be really fascinating. How would he react to spells and potions? Another plot point could be the wizarding world's reaction to Dexter's methods of dealing with 'bad guys'. They might see it as a form of dark magic in their own right. And then there's the potential for Dexter to discover some hidden secrets in the wizarding world that are related to his own past or his 'dark passenger' that could change everything he thought he knew.
One interesting plot point is when Saitama's physical strength is pitted against magic. For example, in some fanfictions, he might try to break a magical spell with his punch, which is a really cool concept. Another is Saitama trying to fit into the social structure of Hogwarts. Since he's from a completely different world, his interactions with the students and teachers can be very comical.
One interesting plot point is when Goku tries to learn magic. It's hilarious to imagine him struggling with a simple levitation spell when he can usually just use his Ki to fly. Another is when Harry Potter tries to learn martial arts from Goku. It's a great clash of two different power - building systems.
A really interesting plot point can be when Gamora tries to use her combat skills in the wizarding duels in the Harry Potter world. It's a clash of two different fighting styles - her physical combat against the spell - casting of the wizards.
The character interactions are really engaging. Imagine Harry Potter trying to reason with Thanos. Harry is used to dealing with Voldemort, who has different motives compared to Thanos. Thanos might not care about the wizarding world's internal politics but only about power. Also, the idea of Hogwarts as a target for Thanos. He might see it as a place full of power sources, like the Philosopher's Stone or the magic in the castle itself. This could lead to epic battles within the hallowed halls of Hogwarts.
Well, one interesting plot point is often the clash of cultures. For example, Widowmaker coming from a high - tech assassin background and suddenly being in a world of magic like Harry Potter's. Another is how her skills as an assassin can be used or adapted in the magical world. Maybe she uses her marksmanship in a new way against magical creatures.
Well, one interesting plot point is when Loki's magic clashes with the magic of Hogwarts. His Asgardian magic is often more powerful and unpredictable, which can lead to some really cool and unexpected magical duels. For example, in some fics, he can create illusions that are far more complex than anything the Hogwarts students are used to. Another plot point is how Loki interacts with the different Hogwarts houses. He might find himself more drawn to Slytherin because of their ambition, but also has some interesting relationships with Gryffindors like Harry, which is a contrast of personalities. Also, Loki's relationship with the Dark Lord Voldemort can be a great plot point. In some fanfictions, he either tries to outwit Voldemort or ends up getting involved in the fight against him in his own unique way.
