Another theme is the alteration of reality. The Infinity Gauntlet can change reality, and in crossovers, this often leads to strange and unexpected situations. For instance, characters from one universe might find themselves in a completely different world due to the gauntlet's power, and they have to adapt. This theme adds a lot of intrigue and adventure to the fanfictions. Also, moral dilemmas are common. Characters have to decide whether to use the gauntlet's power for good or evil, and this internal struggle makes for some really interesting storylines.
There's also 'Infinity Gauntlet and the Justice League Crossover'. In this fanfic, the Infinity Gauntlet somehow finds its way into the DC universe and the heroes of the Justice League have to deal with its power. It's a really exciting read as it combines the powers and dynamics of two very different superhero universes.
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.
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 this fanfic scenario, the Infinity Gauntlet could also attract the attention of the White Walkers. If they got hold of it, they could use it to spread their icy grip across all of Westeros and beyond. They might use the Space Stone to teleport their armies, or the Time Stone to reverse the defeats they've suffered, making them an even greater threat to the living.
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.
