The interactions could also be really fun in a more light - hearted sense. Naruto might introduce the heroes to ramen, and they would all bond over a big bowl of it. Meanwhile, the students could teach Naruto about modern technology which is so different from what he has in his own world. And in battle situations, the more strategic minds of the Hero Academia characters could work together with Naruto's brute force and quick thinking to defeat enemies.
The students of UA High School would be really curious about Naruto's powers. Deku, for example, would probably be constantly asking Naruto about how his chakra works. And Naruto would be amazed by the Quirks of the heroes. He might try to figure out if there's a way to combine his jutsu with their Quirks.
Superman and All Might would probably have a great deal of respect for each other. They are both symbols of hope in their respective universes. All Might might be a bit in awe of Superman's natural powers, while Superman would admire All Might's determination despite having a quirk that was slowly fading. They could exchange stories about their battles and how they inspire others.
Chat Noir's Cataclysm power, which can destroy anything it touches, could be really dangerous in the My Hero Academia world. If he were to use it on a building, it would be similar to how some villains with destruction - based Quirks operate. However, the heroes in My Hero Academia might be able to use their powers to contain or redirect the effects of Cataclysm. For example, someone like Cementoss could create barriers to stop the spread of the destruction.
Villain Deku would likely be very manipulative towards Fem Bakugou. He might try to use her anger and pride against her. For example, he could taunt her about how the hero system has failed her in some ways, making her question her loyalty. Bakugou, on the other hand, would probably respond with aggression at first. She would not take kindly to Deku's villainous ways and would try to attack him. But as she realizes Deku has some valid points about the hero system, she might start to listen more and their interactions could become more of a debate rather than just physical combat.
The heroes in My Hero Academia would be in awe of Spider - Man's abilities. His ability to climb walls and swing from buildings would be something new to them. They might try to incorporate some of his moves into their own fighting styles. Midoriya would look up to Spider - Man as another symbol of hope, just like All Might.
Midoriya would probably be very empathetic towards the Breakfast Club characters. He'd try to encourage them to be their best selves, like he does with his classmates in My Hero Academia. Bakugo, on the other hand, would likely be dismissive at first. He might see them as weak. But as time goes on, he could start to respect their unique qualities. Uraraka would be friendly and inclusive, making the Breakfast Club members feel welcome.
The students of U.A. High would bring a sense of youthful energy and naivete to the interaction. They'd be curious about the powers of the Avengers and their technology. The Avengers, in turn, would be protective of the young heroes at first. For instance, Hulk might initially see the students as too fragile. But as they face challenges together, they'd develop mutual respect. The different personalities, from the cocky Bakugo to the calm and calculating Shoto, would create a rich tapestry of character interactions with the diverse Avengers.
One idea could be a crossover where Naruto's world is invaded by villains from Hero Academia led by All for One. Naruto and his friends team up with the heroes from Hero Academia to fight back. They could learn new techniques from each other, like the heroes learning chakra control from Naruto.
Naruto would probably be very excited to meet the Big Hero 6 crew. He'd be eager to learn about their technology. Hiro might be a bit intimidated by Naruto at first but would soon realize they could be great friends. GoGo would be interested in Naruto's speed and agility, and might challenge him to a race. Baymax would be very curious about Naruto's body functions, especially related to chakra. Sakura could bond with Honey Lemon over their shared interest in science, although Sakura's knowledge is more in the medical - ninja field.
In a 'naruto gotham fanfic', Catwoman could be intrigued by Naruto's agility and his different approach to getting around. She might playfully challenge him to a race across the rooftops of Gotham. Meanwhile, Naruto would be trying to understand the complex web of relationships between the heroes and villains in Gotham and would be constantly making missteps due to his lack of knowledge of the city's ways.
Let's think about Bakugo's Explosion Quirk and Spider Man's powers. Spider Man could use his webs to contain and direct Bakugo's explosions in a more controlled way. Bakugo could learn from Spider Man's stealth and how to approach enemies more quietly before unleashing his explosive attacks. Also, Spider Man's spider - sense could help him anticipate Bakugo's more impulsive attacks and react accordingly.
