Iron Man's technology could be combined with the magic of the wizarding world. For example, he could use his repulsor rays along with a magic amplification spell. Harry Potter's ability to use the Patronus charm could be used in tandem with Captain America's leadership skills to inspire the combined group in a battle.
Thor's hammer, Mjolnir, could potentially be enchanted with some powerful wizard spells. This would make it even more formidable in combat. Hermione's vast knowledge of magic could be used to upgrade the Avengers' equipment. For instance, she could put a spell on Hawkeye's arrows to make them seek their targets more accurately. Also, the Hulk's super strength could be enhanced by some potions from the wizarding world, making him even more of a force to be reckoned with in battles against powerful foes.
Edward's alchemy skills and Harry's magic could combine in combat. For instance, Edward could transmute the environment to create barriers or platforms, while Harry uses spells to attack over or through these structures. Hermione's knowledge of magic and Edward's knowledge of alchemy could lead to some amazing new discoveries. They could combine their research skills to find solutions to problems that neither world has faced before.
Well, for instance, Captain America's leadership skills could be combined with North's knowledge of different realms. North could lead the Avengers into his world if they needed to hide or strategize in a different environment, and Cap could keep everyone in line and focused on the mission.
Imagine if the Geass power could be used to control magical creatures in the Harry Potter world. Lelouch could use his Geass on a Hippogriff or a dragon to do his bidding. At the same time, wizards and witches could use their magic to enhance the Geass. For example, a spell could be cast on a Geass user to make their power last longer or be more powerful. And the Hogwarts houses could each have a different approach to using the combined abilities. Gryffindors might be more bold in using the new powers, while Ravenclaws would be more strategic and Hufflepuffs more ethical in their use.
The Avengers' superpowers and the magic of Harry Potter characters can combine in many ways. For instance, Captain America's combat skills combined with Harry's ability to use spells like Expelliarmus could make them a formidable duo in a fight. They could teach each other new fighting techniques.
Harry's ability to use magic like the Patronus charm could be combined with Naruto's Rasengan. Maybe Naruto could infuse his chakra into Harry's magic, creating a more powerful and unique attack. Hermione's knowledge of spells could be used to enhance the ninjas' strategies. For example, she could create a spell that would make the ninjas' clones more durable, similar to how they are in the Naruto world but with a magical twist.
Harry Potter's magic could be used in tandem with Emiya's archery. Harry could use a levitation charm to guide Emiya's arrows with more precision, or use a protection spell on Emiya while he is shooting. They could also combine their skills in a strategic way during battles. For example, Emiya could draw the attention of the enemy with his archery while Harry sneaks up and uses a powerful magic spell from behind.
Well, Thor and Hagrid would probably get along great. They both have a love for big, powerful creatures. Thor could be interested in the magical beasts in the Forbidden Forest, and Hagrid would be in awe of Mjolnir. Then there's Iron Man and the Weasley twins. The twins would be fascinated by Stark's technology and would try to figure out how to incorporate some of it into their joke products. Stark, in turn, might be amused by their creativity and chaos - causing abilities.
If Naruto was in the Splatoon world, his Shadow Clone Jutsu could be used in interesting ways. He could send clones to cover more ground during an ink battle, confusing the enemy. And for the Inkling's part, their ability to swim in ink could help Naruto move around in ink - filled areas more easily. They could also use their ink guns to provide cover for Naruto while he attacks up close.
Well, if Izaya from Durarara and Shikamaru from Naruto were to team up, Izaya's intelligence in manipulating people and Shikamaru's strategic thinking could create some really devious plans. Shikamaru could use his shadow - binding jutsu to physically restrain opponents while Izaya uses his words to mislead and confuse their enemies. Another example is if Celty's shadow powers were combined with Naruto's chakra - enhanced strength. Naruto could use Celty's shadows to extend his reach in battle, like creating shadow - arms that are empowered by his chakra.
Naruto's ability to use chakra and his shadow clone jutsu could be combined with the Ninjago ninjas' elemental powers. For example, Naruto could create shadow clones to help Kai with his fire - based attacks in a battle.
