They can be blended by having crossovers of characters. Imagine Harry Potter characters being resurrected in the Avengers universe. Harry could use his magic skills to help the Avengers in their battles. Or an Avenger could be sent to the Harry Potter world after a near - death experience and learn about their magic and how it relates to life after death. They could then bring back that knowledge to their own universe and apply it in a different way, like using it to bring back a fallen teammate in a more magical way rather than just through science - based means.
In fanfiction, the life - after - death aspect can be used to create a new plot. For instance, the souls of dead Avengers could be sent to the Harry Potter world. There, they could be given a second chance at life by learning magic. They might have to attend Hogwarts and learn about the secrets of life and death in the wizarding world. This could change their perspective on life and death when they return to their own universe. It could also introduce new powers and abilities to the Avengers based on the magic they learned in the Harry Potter world.
A really interesting concept is the idea of the Deathly Hallows in the Harry Potter world having an impact on the Avengers. Maybe the resurrection stone could be used to bring back a fallen Avenger. This would bring up a lot of ethical questions, like in Harry Potter, about the rightness of bringing back the dead. Another concept could be the Avengers dealing with the Dementors from Harry Potter. The Dementors could be in the Avengers universe sucking out the happiness of the superheroes, and they would have to find a way to combat them using their own skills and technology combined with any magical knowledge they can get from the Harry Potter world.
It can add a whole new layer of mystery. If a character comes back from the dead, it might lead to a search for the reason behind their return. Is it a dark magic at work? Or is it some sort of divine intervention within the wizarding world?
One way is through character creation. For example, a new character could be based on a Norse god or goddess, with their powers and personalities reflected in the Harry Potter world. So, like a character inspired by Thor could have the power of lightning in the magical context of Hogwarts.
The worlds can be blended by having Barbie visit Diagon Alley. She could be amazed by all the magical items and use her fashion sense to customize her wizarding robes. For instance, adding some sparkly elements that are typical of Barbie's style.
The blend can occur through the use of magic in relation to trigonometry in solving problems. For example, in a fanfiction, a magical creature is lost in a forest that is magically generated with trigonometric patterns. The characters need to use their knowledge of both magic and trigonometry to find the creature. Also, a character's magical power could be related to their understanding of trigonometry, so as they learn more math, their magic becomes stronger and more versatile.
Well, often in such fanfiction, the magic systems are combined. For example, spells from Harry Potter like 'Expelliarmus' might be used in the Skyrim setting. Writers might have a character who is a wizard from Hogwarts suddenly find themselves in Skyrim and use their magic there. It creates a really interesting crossover where the different rules and powers of each magic world collide.
In some fanfictions, the Industrial Revolution might be incorporated into the Harry Potter world by introducing new magical devices created with industrial - era concepts. For example, there could be magically - powered factories in the wizarding world producing potions or wands on a larger scale. This could change the economy and social structure within the wizarding community, as mass production might lead to different power dynamics among the wizarding families who own these new industries.
One way to blend them creatively could be by having Mary Poppins visit Hogwarts. Maybe she could use her magical nanny skills to teach the students some unique lessons, like how to clean up a potion spill with just a snap of her fingers. She could also interact with the magical creatures there, perhaps taming a hippogriff in her own special way.
Well, you could start with the idea that the Duel Monsters exist in a hidden part of the wizarding world. Wizards have been using them secretly for centuries, but it's not common knowledge. Then, a young wizard stumbles upon this secret and starts to explore it, integrating Duel Monsters into his regular duels at Hogwarts.
A good way is to focus on their shared traits. Both Harry and Daryl are survivors. Harry has survived Voldemort's attacks and Daryl has survived the zombie apocalypse. So, in fanfiction, they can bond over their experiences of facing tough odds. For instance, they could exchange stories of loss and how they overcame it.
