The theme of survival is likely to be prominent. In an 'infinty war' scenario, characters would constantly be struggling to stay alive. They'd have to adapt, find new ways to defend themselves, and make difficult choices to ensure their own survival. Another theme could be the loss of humanity. With the never - ending nature of the war, characters might start to lose their sense of morality and what it means to be human as they are forced to do things they wouldn't normally do just to keep fighting.
There are various 'infinty war novels' out there. Some might explore the themes of infinite battles between different factions. For example, a novel might focus on a war that seems to have no end, with characters constantly facing new challenges and moral dilemmas. The settings could range from a post - apocalyptic world to a far - flung intergalactic battlefield.
I'm not sure specifically as I haven't read it. But generally, a novel titled 'the gauntlet' might be about a challenging journey or a series of difficult tests that the characters have to face.
A great infinity gauntlet story could also be fan - made ones. There are some amazing fan fictions out there. Some focus on alternate universes where different characters get their hands on the gauntlet first. For example, a story where Loki manages to steal the gauntlet before Thanos. It explores how his mischievous nature would play out with such ultimate power at his disposal. He might not have the same grand plans as Thanos but would surely cause chaos in his own unique way.
Maybe there's a group of characters. For instance, there could be a mentor figure who guides the main character through the gauntlet. And there might be an antagonist who has set up the gauntlet or is trying to stop the main character from completing it. Without reading the novel, it's all speculation.
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.
