Wizards could use magic to create magical habitats for the dinosaurs. These habitats could have special properties like self - cleaning, or they could be enchanted to provide the perfect climate and food sources for the dinosaurs. This would change the whole dynamic of how Jurassic World operates, with magic being a new tool for dinosaur conservation and study.
The magic system could be incorporated by having Hogwarts - like schools in the MHA universe. Teachers could teach spells and potions, and students would develop their magical abilities as they do their quirks. Magic could also be used in combat situations in the MHA world. For instance, a character could use a levitation spell to gain an advantage in a fight against a villain. This would add a new layer of strategy to battles in the MHA world.
Magic could be used to enhance the cars. For example, a spell could be cast on the engines to make them faster or more fuel - efficient. Also, invisibility spells could be used on the cars so that they can evade enemies during a chase.
Archery could be incorporated by having enchanted arrows. For example, arrows that are charmed to always find their target no matter how well - hidden it is. Or arrows that can pass through magical shields if the right incantation is used when shooting them.
One way could be by having the house - elves start a revolution. They are an oppressed group in the wizarding world, similar to the working class in a capitalist society. They could demand equal rights, fair treatment, and an end to their enslavement, much like the goals of a communist revolution.
The Mantis could be a magical creature that lives in the Forbidden Forest. It could have a special connection to the forest's magic and be a guardian of some sort. For example, it might protect a hidden grove of ancient magical trees.
One way could be through a crossover spell. Maybe a powerful dark wizard in the Harry Potter universe discovers a way to create a Rinnegan - like power. They might use it to gain ultimate control over magic, similar to how the Rinnegan gives great power in Naruto. This could lead to a new kind of threat that Harry and his friends have to face.
One way could be through a magical spell gone wrong. Maybe a spell that was meant to transform an object into a helper, like in Beauty and the Beast, but instead it affects a character in the Harry Potter universe in a similar way. For example, a student might be turned into a beast - like form and only the love of another can break the spell, much like in the original Beauty and the Beast story.
Well, you could have spells from Harry Potter work in the Sekirei world in unique ways. For example, the Wingardium Leviosa spell could be used to levitate Sekirei during battles, giving them an unexpected advantage. Or the Imperio curse could be modified to control certain non - sentient elements in the Sekirei world, like the mechanical devices that are sometimes part of the Sekirei battles.
Well, it could be a new type of magic that was long forgotten but is suddenly rediscovered. For instance, a hidden spell book is found in the Room of Requirement. The magic in it is based on wishes. The caster has to have a pure heart and strong intentions for the wish to work. It might use the power of the caster's own magic core, so if someone has a weak magic core, their wishes might be more limited in scope.
One way could be that Harry Potter uses the time - turner to go back to the World War II era. He might use his magic to help those in need during the war, like protecting civilians from bombings or helping the resistance. Maybe he teams up with some muggles who are later revealed to have a latent magical ability, which was never explored due to the secrecy of the wizarding world.
