The Infinity Gauntlet would likely cause chaos. In My Hero Academia, society is built around the concept of Quirks and how they are used. If the Infinity Gauntlet entered this world, it would introduce a new form of power that is not based on genetics but on an external, extremely powerful object. This would disrupt the existing balance between heroes and villains. Villains might see it as a way to finally achieve their goals of domination, while heroes would have to figure out how to deal with a power that is far beyond what they are used to facing.
All Might could be a likely candidate. He's the symbol of peace in the My Hero Academia world and has a strong sense of justice. If he were to get the Infinity Gauntlet, he would probably use it to protect the world and keep the balance between heroes and villains. His already incredible strength combined with the power of the Infinity Gauntlet would make him nearly unstoppable.
Well, it could completely change the power dynamics. Heroes might be tempted to use it to stop villains once and for all. But it could also corrupt them, just like in the original Infinity Gauntlet story in the Marvel universe. Imagine All Might with the gauntlet, he could probably wipe out all the villains in an instant, but would he be the same hero afterwards?
A character could find it by accident. Let's say Deku is exploring an ancient, hidden ruin during a school trip. He stumbles upon a strange object that he doesn't recognize at first. As he investigates further, he realizes it's the Infinity Gauntlet. He then has to figure out what to do with it, knowing that it holds incredible power and that many people in his world would want it for their own purposes.
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.
Well, if Naruto had the Infinity Gauntlet, the story would change drastically. First, he could easily defeat his enemies like Madara or Kaguya with just a snap. No more long and arduous battles. Second, the power dynamic in the ninja world would be completely shifted. Naruto might use the gauntlet to bring true peace, not just the temporary peace they had before. He could potentially reshape the world according to his ideals without having to convince others through his usual means of talk and fight. Third, his friends might view him differently, perhaps with a bit of fear or awe. But Naruto being Naruto, he would still try to use the power in a positive way, but it would be a whole new ball game in the Naruto universe.
In a fanfiction scenario, the Hulk might be a result of a secret experiment by the League of Villains to create an ultimate weapon. But instead of being fully controllable, he breaks free and becomes a wild card in the power dynamics of the My Hero Academia world. His presence would disrupt the existing balance between heroes and villains as everyone tries to either control or destroy him.
Well, it could be about the heroes from My Hero Academia getting caught up in the events of Infinity War. Maybe Thanos targets the quirks in the MHA universe. Deku might try to use his One For All to stop Thanos, seeing it as a great evil. And the Avengers could be confused by the existence of quirks at first.
Batman in the My Hero Academia world would likely be a bit of an outsider at first. His dark and brooding nature might contrast with the more colorful and often optimistic characters in MHA. However, his intelligence would be highly respected. He could use his detective skills to help solve some of the mysteries that pop up in the MHA world, like the origin of certain quirks or the identity of villains who are hiding in plain sight. And his martial arts expertise would make him a formidable opponent in battles against villains.
First, think about their Saiyan powers and how they would translate in the My Hero Academia world. For example, a Saiyan's ability to increase power level could be like a quirk that gets stronger over time. Consider their backstory, like maybe they're a Saiyan from another planet who ends up in the MHA world. Also, their appearance can combine Saiyan features like a tail and spiky hair with the MHA style of clothing.
He might find it in a hidden chamber in Hogwarts. Maybe it was left there by a powerful wizard from long ago who had some connection to other universes.
