In some fanfictions, the moment when Peter saves a large number of people from a major disaster is a key moment in his transformation. He sees the impact he can have on so many lives, and this gives him the confidence and determination to fully embrace his role as a hero. He realizes that he has the ability to make a real difference in the world.
One possibility could be that Peter Parker, in a moment of extreme stress and anger, is exposed to the Carnage symbiote. Maybe he's facing a great loss, like the death of a loved one, and his emotions make him a prime target for the symbiote's takeover. The Carnage symbiote, known for latching onto negative emotions, might sense his turmoil and bond with him, thus leading to his transformation into a form influenced by Carnage.
In many Peter Parker becomes a hero fanfictions, he overcomes his inner demons through self - reflection. He realizes that his power comes with great responsibility. For example, when he faces the death of a loved one, he uses that pain as motivation to be a better hero, not letting grief turn him into a darker version of himself.
One possible reason could be extreme grief. If he lost someone very close to him, like Aunt May in a particularly cruel way, it might shatter his moral compass. Another reason could be mind control. Maybe a powerful villain manages to get into his head and twist his thoughts and values. Also, if he was constantly betrayed by the people he trusted, such as the Avengers or his friends at school, he could gradually turn bitter and evil.
The moment when MJ saw Peter in his Spider - Man suit for the first time was crucial. It was a moment of shock but also of new - found admiration. Also, when they had to face a powerful villain together, it showed how much they relied on each other. And those quiet evenings when they just sat and watched the sunset, sharing their dreams and fears, were important steps in their love story. These moments, big and small, all contributed to the growth of their relationship.
In a fanfiction where Peter Parker becomes Venom, it could be due to a scientific experiment gone wrong. Maybe Oscorp was working on a new symbiote project, and Peter, being the curious and heroic type, gets involved accidentally. The transformation would change his personality, making him more aggressive at first as he struggles to control the new power. He might initially see the symbiote as a curse but later learn to use it for good, in a different way than he does with his Spider - powers.
One idea could be that Peter uses his spider - abilities to help on the farm. For example, he can use his super strength to lift heavy farming equipment or his agility to quickly harvest crops. Maybe he becomes a farmer to get away from the chaos of the city and superhero life for a while, finding peace in the simple life of farming.
His relationship with Aunt May could become strained. Since becoming a Savitar fan, Peter might be more reckless in his pursuit of power. Aunt May, who is used to the more cautious Peter, would be worried. His friends like Ned and MJ would also be concerned. Ned might try to talk him out of it, fearing that Peter is getting in over his head. MJ, on the other hand, might be intrigued but also worried about the changes in Peter.
His relationship with Mary Jane would likely change a great deal. She might be in awe of him, but also a bit intimidated. Peter, now a god, would have to struggle to maintain the same level of intimacy they once had. With his friends like Ned, they might see him more as a protector. Ned would probably be excited about Peter's new powers at first, but then realize that their friendship has become more complex. And his enemies? They would either be terrified of him or try to find a way to bring him down.
One of the most memorable ones is when Peter tries to cook while wearing his Spider - Man suit. He's so used to his enhanced reflexes that he thinks he can flip pancakes like a pro. But instead, he ends up with pancake batter all over the kitchen and himself. It's a classic case of overconfidence.
In some fanfictions, Peter Parker's attempts at normal teenage life while being Spider - Man lead to hilarious situations. For example, he might be in a hurry to change into his suit for an emergency, but he accidentally puts his suit on backwards. Or there could be a moment where he's trying to keep his identity a secret from his friends during a school play. He's so focused on not revealing himself that he forgets his lines and starts ad - libbing in a really goofy way that has the whole audience laughing, thinking it's part of the act.
