For the heroes, there would be intense grief. They've lost friends, family, and comrades. Iron Man might feel an overwhelming sense of guilt for not being able to stop Thanos, thinking about all the lives that could have been saved. Captain America would be in despair, seeing the world he fought for fall apart so suddenly.
Perhaps in the fanfiction, the snap is only the first step of a much larger plan by Thanos. After the snap, he uses the resulting chaos to try and reshape the universe in his image. The heroes must not only deal with the loss from the snap but also stop Thanos' grander scheme which involves complex magical and technological elements that they have never faced before.
In such a fanfiction, perhaps the world would immediately change. With Thanos gone in a snap by Spiderman, the Avengers might be left in shock and then relief. They'd start to rebuild the universe that Thanos had damaged. Maybe Spiderman would become an even bigger hero overnight, and people would look at him in a whole new light, seeing his power as not just about swinging around New York but having the ability to change the fate of the entire universe.
In this fanfiction, perhaps Spiderman snaps Thanos out in a different way than how Thanos did the original snap. Instead of using the Infinity Stones in a traditional sense, he could use his own unique spider - powers combined with some sort of magical or technological element. This would make for an interesting twist on the well - known story and could lead to a whole new set of adventures for Spiderman and the other heroes.
It could be that the Iron Man's technology, which was used in the fight against Thanos, had some sort of hidden function. Spider - Man discovers this function while tinkering with the leftover tech. This function allows him to harness and concentrate a large amount of energy, similar to the power required for the snap. So, with his quick thinking and scientific knowledge, he figures out how to use it to snap Thanos out.
It would have a huge impact. For starters, the threat of Thanos would be gone, which means the heroes who were constantly on edge preparing for his attacks could finally relax. However, the power vacuum left by Thanos could also lead to new villains emerging, seeing an opportunity to take over the power that Thanos once held.
A plot twist might be that the snap doesn't completely get rid of Thanos. Instead, it splits Thanos into multiple versions of himself, each with different levels of power and different personalities. Spider - Man then has to face not just one, but several Thanos - like entities. Also, the snap could have unforeseen effects on the Infinity Stones. Maybe they scatter across different dimensions, and Spider - Man has to retrieve them to prevent a greater catastrophe, all while still dealing with the remnants of Thanos.
One day, the son wanted to make a surprise for his mom. He used his fingers to make finger puppets. He made a little rabbit and a fox. Then he put on a show for his mom using his finger puppets. His mom was delighted and laughed a lot. It was a sweet moment of the son's creativity and the mom's enjoyment.
In fanfiction, if Harry Potter snaps his wand, he might lose a great deal of his magical power. His wand is his primary tool for casting spells, so without it, he'd be in a very vulnerable position. He could start to explore alternative forms of magic or seek out a new wand, perhaps through some extraordinary adventure. This could also lead to him relying more on his friends and the skills he has developed outside of wand - based magic.
