Who would be the most likely characters in My Hero Academia to be involved in an Infinity War - like scenario in a fanfic?

Mina. She has a very energetic and positive personality. She's always up for new and fun things, so she would likely be the most into the fanfic, enjoying all the creative ideas and new takes on their world and characters.

I think the students like Kaminari and Sero would be involved. Kaminari with his goofy personality might initiate some pranks, and Sero could use his tape quirk to set up some elaborate prank setups. Also, the teachers like Aizawa could be involved. He might play a prank on the students to teach them a lesson in a rather unorthodox way. Another character could be Todoroki. His rather stoic nature could be a great contrast to the chaos of a prank.

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.

Obviously, Izuku Midoriya will be the central character. His friends from U.A. High like Ochaco Uraraka and Tenya Iida are likely to be involved. They would be there to support or oppose Izuku depending on the nature of the spiral he's in. Also, All Might might play a role as Izuku's mentor, guiding him through whatever challenges the spiral presents.

In a darker take, even some of the younger students at U.A. High could die. This would be a very emotional and impactful event. It would show the harsh reality of the hero world and how not everyone is guaranteed to survive, no matter how much potential they have.

One possible plot could be that the villains in My Hero Academia somehow get their hands on the Infinity Stones. They could use the power of the stones to start warping reality. For example, they might use the Reality Stone to make the heroes' quirks ineffective or change the very nature of the hero society. The heroes would then have to band together, not just from UA but from all over the world, to try and stop the villains from completely taking over. They would need to figure out how to combat the power of the Infinity Stones, perhaps by finding some sort of counter - quirk or ancient hero relic.

Izuku Midoriya is a likely character. He has a strong sense of justice and is always willing to put others before himself. His determination to be a hero makes him a prime candidate for self - sacrifice. Bakugo Katsuki could also be involved. Despite his tough exterior, he has a good heart and would sacrifice for his friends and to prove himself as a true hero.

All Might from My Hero Academia could also be a good choice. His strength and experience would be valuable. And from Nanatsu no Taizai, Ban. Ban's immortality and combat skills could complement All Might's power. They might form an alliance because they both have a strong will to protect the weak.

Todoroki is also a popular choice. His complex backstory and powerful quirk make him an interesting candidate for quirk swaps. Swapping his quirk with someone like Momo, who has a creation quirk, could lead to really unique storylines.

In a My Hero Academia Civil War fanfic, the heroes-in-training could be split in various ways. Class 1 - A students like Deku might side with the more traditional hero values, aiming to uphold the law and protect civilians without overstepping boundaries. Bakugo, on the other hand, could potentially be on a side that believes in a more aggressive approach to taking down villains, seeing the current hero system as too restrictive. Characters like Todoroki, with his complex family history, might be torn between the two sides, trying to find a middle ground that reconciles his father's strict hero ideology and his own beliefs about justice.
