Well, in a fanfiction world, anything can happen. Maybe Harry Potter discovers some magical connection between the wizarding world and the Marvel universe. He could find a spell that allows him to access the world of Spider - Man, and then he becomes fascinated with Spider - Man's abilities and his sense of justice.
Imagine that after the defeat of Voldemort, Harry is feeling a bit lost. He's always been the hero in the wizarding world, but now he's looking for something new. One day, he stumbles upon a strange object that transports him to New York City in the Spider - Man universe. He witnesses Spider - Man in action, swinging from building to building and saving people. Harry is impressed by Spider - Man's courage and his ability to use his powers for good without any formal training like the magic he has. So, he becomes a big fan and starts learning more about this new kind of hero.
If Spider - Man becomes a spider in fanfiction, the story might focus on his struggle to regain his humanity. He could encounter a magic spell or some advanced technology that has the potential to transform him back. Along the way, he would learn more about the spider world and how it differs from the human world. He could also meet other creatures that are half - human and half - spider, and they could either help or hinder his journey.
In the 'Spider Man Becomes Toxin Fanfiction', it could be that Spider Man is tricked into wearing a piece of alien technology that is actually a Toxin - like symbiote in disguise. The symbiote slowly takes over his body and mind, turning him into Toxin. Additionally, the fanfiction might explore the idea that Spider Man's own self - doubt and internal struggles somehow attract the Toxin - like transformation. He may be feeling inadequate or guilty about something, and this negative energy makes him a prime target for the Toxin transformation.
Maybe Spider - Man is being attacked by some dark creatures that are immune to his usual attacks. Harry Potter arrives on the scene, having sensed the disturbance in the magical fabric. He casts protective spells around Spider - Man and then uses his Patronus charm to drive away the dark creatures. They then team up, with Harry teaching Spider - Man some basic defensive magic spells in case he faces such threats again.
This new interest could make Harry more adventurous in a different way. He might be inspired by Spider - Man's acrobatic skills and start to incorporate more physical feats into his own actions. Also, his sense of justice could be further refined as he sees how Spider - Man operates in a non - magical world. He may also become more interested in muggle technology as he tries to understand how things work in Spider - Man's world.
One possibility could be through a magical accident. Maybe a spell gone wrong during a Hogwarts experiment transports Harry to the Bleach universe. There he witnesses Grimmjow's power and charisma and becomes a fan. Another reason could be that Harry, tired of the constant danger in his own world, is drawn to Grimmjow's fearless and brash attitude. It could also be that a cross - universe book or some form of media makes its way into Harry's hands, introducing him to Grimmjow and making him a fan.
One way this could be possible in a fanfiction is through some sort of multiverse or dimension - hopping concept. Maybe there's a rift in the fabric of the universes that causes the DNA of Spider - Man to somehow merge with the world of Naruto. Another idea could be that some sort of powerful magic or jutsu is involved that links the two characters in a way that Naruto ends up being his son. It's all about creative and out - of - the - box thinking in fanfiction.
Well, one possibility could be that Harry has some of Spider - Man's powers. Maybe he can climb walls and has a super - sense like Spider - Man, which he uses to his advantage at Hogwarts. He could use these powers to explore hidden areas of the castle or escape from dangerous situations, like when facing Voldemort or his Death Eaters.
The characters could interact in a very interesting way. For instance, Hermione could be fascinated by Peter Parker's web - shooters and try to figure out the science behind them, using her vast knowledge. At the same time, Peter could be in awe of the magic Hermione can do. They could exchange ideas, with Hermione perhaps trying to find a magical equivalent to the web - shooters, and Peter helping her understand some basic principles of physics that might be related.
Well, for instance, Peter Parker (Spider - Man) could be invited to Hogwarts as a special guest lecturer on the concept of 'great responsibility' which he could relate to his own superhero experiences. He could show the students his web - shooters and how he uses them to protect the city. The Hogwarts students, especially the Gryffindors, would be very interested in his stories.
The interaction of their powers would be fascinating. Harry's magic could be used to heal Spider - Man if he gets injured during a fight. Spider - Man's Spider - Sense could alert Harry of any oncoming danger, even magical threats that Harry might not be aware of immediately. Also, Harry could use spells to create distractions while Spider - Man uses his stealth to approach enemies unnoticed. This synergy between magic and superhuman abilities would create a very unique and exciting dynamic in the fanfiction.
