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.
Definitely. The Infinity Gauntlet comics came out earlier and laid the foundation for the concepts and characters seen in Infinity War. There are some differences, but the comics serve as a precursor.
Avengers Infinity War is largely based on the Infinity Gauntlet comic. Many key elements and plot points are drawn from it, but there are also some creative adaptations and additions to make it work for the cinematic universe.
Yes, in some fanfiction he can survive. Writers often give him special abilities or plot armor that allows him to endure the power of the Infinity Gauntlet. Maybe he has some sort of new technology that he's developed which can help him manage the power and not be completely destroyed by it.
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.
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.
One interesting fanfiction could be where Tony Stark uses the Infinity Gauntlet to reverse the Snap in a completely different way than in the movies. Maybe he has to sacrifice his own intellect to power the Gauntlet fully, leading to a whole new set of challenges for the Avengers to deal with.
In a Batman Infinity Gauntlet fanfiction, Batman would face a moral dilemma. The power of the gauntlet is immense and corrupting. He would have to struggle with whether to use it for what he believes is the greater good or to resist its allure completely. He could also encounter other powerful beings from the DC universe who either want to take the gauntlet from him or help him control its power.
