Well, in this fanfiction scenario, if Wanda could reverse the snap, it would be a game - changer. Vision was a key part of her life, and her love for him could fuel this power. But it wouldn't be easy. There would be a huge energy cost, and she might have to sacrifice something in return. Maybe she'd have to give up some of her own life force. And then there's the matter of Thanos. He wouldn't just stand by and let her undo his 'work'. There would be a massive battle, and the outcome would be uncertain.
Maybe they could use the Quantum Realm not just for time travel but also to create some sort of energy wave that counteracts the effects of the Snap. The characters in the fanfiction could figure out a way to harness the unique properties of the Quantum Realm, which is already a bit of a mystery in the MCU, to fix what Thanos did.
In this type of fanfic, the Infinity Stones could have a very different effect in the Harry Potter universe. For example, the Time Stone could be used to reverse dark spells or resurrect fallen wizards. However, the Stones' power might also be limited by the magic rules of the wizarding world. The fanfic could delve into how the characters from both universes adapt to the presence of the Stones and how they use or misuse their power.
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.
