One way Peter Parker could become a Batman fan is through multiverse exploration. Maybe in a world where the heroes' stories are more intertwined, Peter discovers Batman's methods of crime - fighting. His detective skills and use of gadgets might intrigue Peter, who is used to more physical powers like his spider - abilities.
Perhaps Peter Parker attends a superhero symposium where they discuss different hero archetypes. There, he hears in - depth analysis of Batman's character. Batman's unwavering dedication to protecting Gotham, despite the odds and his own personal tragedies, could inspire Peter. He may then become a huge fan, even incorporating some of Batman's tactics into his own crime - fighting in New York.
Well, if Peter Parker becomes Flash in fanfiction, he might use his new super - speed in really interesting ways. For example, he could swing between buildings as Spider - Man even faster. Maybe he'd combine his spider - sense with the Flash's ability to see things in slow motion, making him an even more formidable hero. He could also use the Flash's speed to create new web - slinging techniques, like using his speed to make the webs shoot out faster and farther.
His costume could potentially change. He might add some darker elements or more gadgets inspired by Batman. He could also start to use his intelligence in a more detective - like way, setting up surveillance around the city to anticipate crime, rather than just waiting for his spider - sense to tingle. This new - found admiration for Batman could make him a more serious and calculated hero.
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 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.
There could be a deeper reason for the fight in the fanfiction. Maybe Flash has accidentally found out something about Peter's double life and is trying to blackmail him. This would lead to a more intense and emotional fight, with Peter having to protect his secret identity at all costs.
Perhaps in this fanfiction, Peter Parker meets the Defenders when they are all investigating the same strange occurrences in the city. There could be a mystery involving some sort of strange energy or new type of criminal organization. The Defenders with their unique skills and Peter with his spider - powers would start to piece together the clues. Along the way, they would have to overcome their differences in approach. For example, Peter is used to working alone most of the time, while the Defenders are a team. But in the end, they would combine their forces to solve the mystery and protect the city.
In this fanfiction, Peter Parker might show off his amazing spider - abilities to the Avengers. Maybe he'll swing around the Avengers Tower impressing everyone.
One scenario could be that the Avengers are facing a new threat that requires Peter's special skills. His ability to stick to walls and his enhanced strength could be crucial. Peter might also introduce a sense of youthful enthusiasm to the group. He could crack jokes during tense situations, which at first annoys some of the Avengers but later they come to appreciate it as a way to lighten the mood.
Well, Loki might see Peter as a new toy to play with. He could mess with Peter's life by using his illusions, like making Peter think his friends and family are in danger. Peter, of course, would try to fight back and save them. This would lead to a chase around the city, with Loki leaving false trails and Peter using his spider - abilities to track him down.
