Well, the Fairy Tail characters can have some interesting interactions with the real - world environment. Consider how Levy would react to real - world computers. She might be fascinated by how much information they can store and try to figure out if she can use her script magic to interact with them. Cana could visit a real - world bar and be disappointed that there's no barrel of her favorite booze like in the Fairy Tail guild. And Laxus might be intrigued by electricity poles, seeing them as a form of weak lightning magic.
In a 'Fairy Tail in Real World' fanfiction, the characters' interactions with the environment can be really diverse. Erza could mistake a large building for a castle and try to storm it thinking it's an enemy stronghold. Happy might get excited about all the fish in a real - world aquarium. And Juvia could be constantly causing rain in dry areas because she's so used to her water - based powers being tied to her emotions in the Fairy Tail world.
The Fairy Tail guild as a whole could work together. They could use their combined magic to create a powerful spell. For example, they could combine the elements of fire, ice, wind, etc. to create a spell that might be able to hold Deathwing back or even send him back to his own realm. They would need to communicate and coordinate well, which would be a challenge given the different personalities in the guild.
Another way is if a Fairy Tail mage visits the My Hero Academia world. Let's say Gray. He could use his ice - make magic to help in rescue operations during a villain attack. And in the process, he could teach some of the students about the importance of controlling their powers and how magic works in his world, which would be a great opportunity for cultural exchange between the two universes.
Goku would likely interact with Natsu in an interesting way. They both love to fight and are always looking for a strong opponent. They might start off as rivals and then become friends. Goku would also probably be friendly with Lucy, being intrigued by her celestial spirit magic.
The characters would likely start off being cautious of each other. For instance, the devils in Highschool DxD might be wary of the mages from Fairy Tail as they have different power sources. However, as they get to know each other, they could start to learn from one another. Gray could teach some of the Highschool DxD characters about his ice - making skills, while Issei could show the Fairy Tail members some of his unique devil techniques.
They could interact more casually. In the original series, there are often battles and serious missions. But at a party, they might just joke around and share funny stories. For example, Gajeel and Natsu could have a friendly competition about who can eat the most food at the party instead of fighting over something serious.
The Fairy Tail characters are used to a world full of magic and guilds. When they enter the Highschool DxD world, they would bring their sense of camaraderie and loyalty. Characters like Erza would immediately assess the situation and try to find a way to protect her friends. In the DxD world, she might find some kindred spirits in the more honorable devils. Meanwhile, the Highschool DxD characters are used to a world of different species and complex power dynamics. They would be curious about the Fairy Tail magic. For instance, the magic items used in Fairy Tail could be very appealing to some of the DxD characters. There could be a lot of cultural exchange and some tense moments as they figure out how to co - exist and whether they can trust each other.
Well, if we think about it, Thor is a very proud and strong warrior. He might initially look down on some of the younger Fairy Tail members, thinking they are weak. But when he sees their determination and the unique magic they possess, he'd start to respect them. For instance, when he sees Lucy summon her celestial spirits, he'd be intrigued as it's a different form of power compared to his.
For Ruby, the concept of Fairy Tail's magic guilds could be really appealing. She might imagine herself being part of one. Yang would find the idea of the S - Class mages interesting and might want to prove herself against them. Weiss would analyze how the Fairy Tail world manages its economy with all the magic and quests. Blake would be interested in the relationships between the different guilds and how they cooperate or compete. All in all, each RWBY character would interact with the Fairy Tail concepts in different ways based on their own traits and goals.
The interactions could be really interesting. Goku's straightforward and somewhat naive personality in the face of new things would contrast with the more complex relationships and personalities in Fairy Tail. For instance, when he meets Mirajane, she would probably be very kind to him, offering him food and a place to stay at the guild. Goku would then repay her kindness by helping out with any threats that come the guild's way. And with Happy, Goku would find his flying ability really cool and might even try to learn how to fly in the same way, which would be a comical scene.
For Zabuza from 'Naruto' in a 'Fairy Tail' fanfiction, he would interact with the characters in a very direct and often violent way. He would see the Fairy Tail mages as targets or obstacles. If he was hired to kill someone in the guild, he would not hesitate to use his sword skills against them. He might not understand the concept of friendship and loyalty that is so strong in the Fairy Tail guild and this could lead to some interesting clashes.
