Well, in a fanfiction scenario where Tony has the gauntlet in Infinity War, he might try to use it to defeat Thanos right away. Maybe he figures out how to control it quickly and unleashes a powerful blast that could turn the tide of the battle.
One possibility in the fanfiction where Tony has the gauntlet in Infinity War is that he could face a moral dilemma. The power of the gauntlet is immense and could corrupt him. However, being Tony Stark, he would likely fight against that corruption. He might use the gauntlet to save his friends who were turned to dust by Thanos' snap. He could also use it to reverse the damage Thanos has done to the universe. But he would have to be careful as the power of the Infinity Stones is not something to be trifled with. There could be unforeseen consequences, like attracting other powerful and malevolent forces in the universe that want the gauntlet for themselves.
In fanfiction, if Tony Stark uses the Infinity Gauntlet, he might be able to rewrite reality in ways that benefit Earth. He could potentially eliminate all threats to the planet, like getting rid of all alien invaders forever. Also, he could use it to solve global problems such as poverty and environmental degradation. He might create a world where technology is so advanced that everyone has a high quality of life.
If Spider - Man has the Infinity Gauntlet in fanfiction, he would likely use it to protect his loved ones first. He could use the Soul Stone to ensure the safety of Mary Jane, Ned, and Aunt May. His approach to using the gauntlet would probably be different from someone like Thanos. Spider - Man is all about protecting the little guy, so he'd focus on using the power for the benefit of ordinary people. He might even use the Stones to improve living conditions in the city, like using the Power Stone to generate clean energy for everyone.
In this fanfiction scenario, Naruto finding the Infinity Gauntlet could lead to some interesting battles. He could use it against his toughest enemies like Madara or Kaguya. But he'd also have to deal with the fact that the Infinity Gauntlet comes from a different universe with different rules. He might struggle to control all the power it holds at once.
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.
He might use it to save his city from all kinds of threats. He could snap his fingers and make all the bad guys disappear, like the Green Goblin and Doctor Octopus. He's a hero, so he'd probably use it for good.
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.
If Percy Jackson had the Infinity Gauntlet in fanfiction, it would completely change the power dynamics. He might use the Reality Stone to create illusions or change the nature of things around him. For example, he could turn the sea into a solid surface for his enemies to struggle on. And with the Power Stone, his physical strength would be off the charts, allowing him to take on even the mightiest of foes with ease.
Maybe the gauntlet starts to communicate with Tony's suit, creating a new kind of power synergy that no one expected.
Well, in this fanfiction, the Joker could find out about Batman having the Infinity Gauntlet. He would then try to steal it, thinking he could create the most chaotic and hilarious situations. Batman would have to fight off the Joker while also dealing with the power of the gauntlet. Maybe the gauntlet gives Batman the ability to see into the Joker's mind and understand his madness better.
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?
