How would Izuku's story change if he got the Infinity Gauntlet in fanfiction?

He might become more serious. Having such a powerful item would weigh on him.

It would change drastically. He'd be much more powerful than before. He could easily end the war against Voldemort.

Well, he'd probably be super powerful. He could use the Infinity Stones' powers to defeat villains with ease. Maybe he could even use the Time Stone to go back and prevent some of the bad things that happened in his world. With the Power Stone, his physical attacks would be off the charts.

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.

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.

He would probably become extremely powerful. He could use the Infinity Stones' powers to defeat Voldemort in an instant. For example, the Power Stone could enhance his magic to an unimaginable level, and the Time Stone might allow him to go back and prevent bad things from happening in the wizarding world.

The plot would be much more complex. Harry could easily defeat Voldemort with the combined power of the Infinity Stones. So the main conflict of the original story would be resolved very quickly.

Naruto would become more confident, not just in his abilities but also in his decision - making. Having the Infinity Gauntlet gives him an edge that no one else has. He might become a bit more reserved as he has to be careful with the power he wields. He can't just rush into things like he used to.

He'd be more confident. Having that much power at his fingertips would make him less hesitant in dangerous situations. He might become a bit more arrogant too, as the Infinity Gauntlet could easily go to one's head.

Naruto would likely see it as a new way to protect his village and friends. He's always been about that - protecting what he loves. But he'd also be cautious because he knows that power can be dangerous. He might think about how to use it in a way that doesn't corrupt him, like how he was careful with the power of the Nine - Tails.
