Peter would face challenges in his personal relationships. His friends and family might worry about him more. And in the superhero community, if there is one in the fan fiction, he might face exclusion or pity. He'd have to prove himself all over again, that he can be a valuable asset without his spider powers, perhaps by being a strategist or a tech - support for other heroes.
One major challenge would be dealing with the villains. They would see him as an easy target now. For example, someone like the Green Goblin might go after him more aggressively, and Peter would have to use his wits and non - power - based skills to survive. He'd also have to face the disappointment of the public who once saw him as a powerful superhero.
The story could focus on Peter Parker's intelligence. He could use his scientific knowledge to create gadgets and outwit villains, much like Batman. For example, he could develop advanced non - spider - power - based web - shooters that have unique functions. Also, his character development could be centered around how he copes with the loss of the powers he once had and how he still tries to be a hero without them.
One major challenge would be keeping the stones safe from villains. Everyone in the Marvel universe who wants power would be after him. Another challenge is controlling the power of the stones. They are extremely powerful and if he misuses them even a little, it could have disastrous consequences. Also, he might face challenges from his own self - doubt. He's used to being a street - level hero, and having this much power could make him question if he's worthy of it.
Often, in fanfic, Peter's new powers come from exposure to other sources related to spiders. It could be a new type of radioactive spider or a spider - themed experiment gone wrong. For instance, he might come across a super - spider in a hidden lab that bites him again, enhancing his existing powers and giving him new ones like the ability to fly using web - wings. Another way is through magical or alien influences. If there's an alien entity that has an affinity for spiders, it might enhance Peter's powers to use him for its own purposes.
One challenge could be hiding his identity. If something happened during the class like his spider - sense going off or a call for help as Spider - Man, he'd have to find a way to deal with it without revealing himself. Another is technical issues. Maybe his web - shooters accidentally fire and damage his computer right in the middle of a lecture. Also, he might be distracted by his superhero duties and miss important parts of the class.
In some fanfictions, Peter Parker might have the power to control spiders other than just having the abilities of one. For example, he could communicate with all spiders and make them do his bidding, like creating a spider army to fight villains. Another power could be the ability to manipulate his webs in more complex ways, such as changing their texture or making them invisible for stealth attacks.
His relationship with Mary Jane could change. Without his powers, he might be more vulnerable, and Mary Jane could become more protective. Instead of being the damsel in distress, she could be the one looking out for Peter. Their relationship could become more of an equal partnership in terms of protecting each other.
Well, the story could focus on Peter relying on his intelligence more. He could become a tech - genius, creating gadgets to fight crime like Batman. For example, he might develop advanced web - shooters that don't rely on his spider - powers but on his engineering skills. He could also team up with other characters who have powers to compensate for his lack of them.
They would also face the challenge of their different power sets. Peter has his spider - powers which are more science - based, and Red Sonja has her strength, sword - fighting skills and some magical knowledge. Combining their powers effectively in battles could be difficult. Also, their friends and allies from their respective worlds might not understand or accept their relationship at first.
One possible scenario could be Peter Parker getting physically hurt during a battle with a powerful villain in a fanfic. For example, he might face off against a new and dangerous foe like a super - enhanced criminal who has some sort of energy - based attacks. These attacks could seriously wound Peter, causing him to struggle not only with his physical pain but also with the fear of not being able to protect the city he loves.
One idea could be Peter Parker using his spider powers in a different era, like the 1920s. He could swing between the old - style skyscrapers and fight crime in a more vintage setting. Another could be Peter having to deal with his powers malfunctioning due to some strange new villain's technology. This would make him have to rely more on his wits and less on his usual spider - strength and agility.
