Deku would be super excited to meet Superman. He would be constantly asking him questions about his powers and how he uses them for good. Superman, in turn, would see a lot of potential in Deku and encourage him to keep growing and using his quirk in the best way possible. Bakugo might be a bit more challenging towards Superman at first, seeing him as a rival, but eventually, he would also come to respect him.
The villains in My Hero Academia would likely be very intimidated by Superman. However, some of the more cunning ones, like Shigaraki, might try to find a way to use Superman's presence to their advantage. Superman, on the other hand, would be very cautious around the villains, as they are different from the ones he usually faces. He would need to quickly understand their quirks and motives to deal with them effectively.
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.
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.
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.
The quirks in My Hero Academia are often very physical and unique to each individual. In a crossover, Uraraka's zero - gravity quirk could be used in space battles in the Star Wars universe. She could disable enemy ships by making them weightless. On the other hand, the Force abilities in Star Wars, like mind control and precognition, could give the My Hero Academia characters an edge in combat. For example, Todoroki could use his ice quirk in combination with a Jedi's precognitive ability to anticipate his opponents' moves and freeze them in place before they can act.
Another possible plot is a competition between Superman and the top heroes in My Hero Academia. They hold a friendly, but intense, competition to see who is the most powerful and heroic. This would not only showcase their different powers and abilities but also how their concepts of heroism differ. It could lead to a lot of character development for both sides as they learn from each other.
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 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.
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.
Genos' robotic enhancements and Kirishima's hardening quirk could create an interesting combination. Genos could provide Kirishima with some technological upgrades to his hardening ability, making him even more indestructible. On the other hand, Saitama's speed could be combined with Iida's engine quirk to create a super - fast movement ability that could outpace almost any villain.
The characters could interact through battles. For example, Bakugo might see the Transformers as a new challenge and try to blow them up with his explosions. He would be amazed by their durability at first. Then he might start to strategize how to take them down. On the other hand, the Autobots could see Bakugo's passion and potential and try to teach him about teamwork, which is something he struggles with.
