Well, in the official Spider - Man lore, lifting a building is not something he's typically known for. But fanfiction is a different ball game. Fanfic writers often like to test the limits of their favorite characters. They could write a story where Spider - Man has to lift a building because, for example, the building has been rigged with a bomb that will destroy the whole city if it falls. To save the day, he uses his spider - sense to find the perfect points of leverage and combines his strength with his acrobatic skills. He might also get some help from his friends in the Avengers or other superheroes in the Marvel universe, which would make for an exciting and unique fanfiction story.
Yes, it could be possible in fanfiction. Spider - Man's strength has been shown to vary in different comic storylines and adaptations. In some versions, he has demonstrated extraordinary feats of strength. In fanfiction, the writer can take this even further. They might imagine a scenario where the city is in great danger and Spider - Man has to lift a building to prevent a catastrophe. Maybe he discovers a new aspect of his powers or gets some kind of power boost from an alien technology or a magical item. It's one of the great things about fanfiction - it can push the boundaries of what we think is possible for our favorite characters.
One possible plot could be that in a universe where the rules are a bit more fluid, Spider - Man finds himself in a situation where he has to lift Mjolnir to save the day. Maybe the Avengers are all incapacitated and only he can reach the hammer. He approaches it with his usual self - doubting self, but his pure heart and strong sense of responsibility allow him to lift it. With Mjolnir's power, he then battles against a powerful villain like Thanos, using both his spider - abilities and the power of Thor's hammer.
Perhaps the skinny boy is part of a group that participates in physical challenges. He is the underdog because of his appearance. But he has been following a strict diet and exercise regime. When it comes time for a big challenge where he has to lift a man, he is ready. His muscles, which he has painstakingly built, come into play. He successfully lifts the man, becoming an inspiration for others in the group who thought looks were everything.
In fanfiction, anything can happen. Writers often like to take creative liberties. Maybe they rewrite Spider Man's origin to include a female identity. For example, they could change Peter Parker's backstory to be a girl with similar spider - like abilities.
A story could start with Spider - Man and Thor in a battle against a common enemy. In the heat of the battle, Thor is knocked out and his hammer is lying there. Spider - Man, without thinking much, tries to pick it up to use it against the enemy and to his surprise, he can lift it. This sudden turn of events then sets the stage for the rest of the story.
Well, in fanfiction, anything can happen. Maybe he discovers an ancient sword with special powers that can help him fight new villains. It could be a magical sword that can cut through any material, giving him an edge in battles.
In the fanfiction, it could be that Spider Man has a personal vendetta against one of the Avengers members. For example, if one of them had a past with a villain that Spider Man has a strong connection to, like if an Avenger unknowingly helped the villain in the past, Spider Man might transfer his hatred for that villain to the Avenger and by extension, the whole team.
Black Cat could be a great partner. She has her own set of skills like acrobatics and thieving abilities which could be used in a different way to fight crime. Her complex relationship with Spider - Man also adds an interesting dynamic to the story.
He would definitely gain the ability to manipulate hellfire. So instead of just shooting webs, he could also shoot out streams of hellfire to either attack his enemies or create barriers. His super strength and agility would likely be enhanced by the demonic power of Ghost Rider. Also, he would get the Penance Stare. With this, he could make his enemies experience all the pain they've ever inflicted on others just by looking at them, which is a very powerful weapon in his new arsenal.
Well, Spider Man's ability to climb walls and swing from webs could be used to quickly move around in different terrains. Cheetah's super - speed could be used to quickly close the gap between them and an enemy. They could use these abilities in a chase scenario, where Spider Man swings ahead and Cheetah runs on the ground below, cutting off the escape routes of a villain.
One possible storyline is that they are brought together by a powerful villain who is a threat to both their worlds. They have to team up to defeat this enemy, and during their time together, they develop feelings for each other. Another could be that Valkyrie is sent to Earth to train Spider - Man in some Asgardian combat techniques, and as they train, a romantic connection forms. Or perhaps Spider - Man accidentally gets transported to Asgard, and Valkyrie takes him under her wing. As he tries to find his way back home, they fall in love.
