One common theme is the idea of spiders as protectors. In many fanfictions, they guard hidden places or secrets in the wizarding world. For example, they might protect an ancient spellbook hidden in a spider - infested part of Hogwarts.
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.
One idea could be that Spider - Man finds himself magically transported to the wizarding world of Harry Potter. He could use his web - slinging skills in Hogwarts, perhaps to help catch the Golden Snitch during a Quidditch match in a very unorthodox way. The Hogwarts students would be both amazed and a bit confused by this strange new hero in their midst.
Definitely Harry Potter and Spider - Man themselves are very popular. Harry's magical abilities and his journey of self - discovery can be paired interestingly with Spider - Man's superhero identity and his struggle to balance normal life and hero duties.
One interesting crossover could be Spider - Man getting lost in the wizarding world of Harry Potter. He might be confused by magic at first but then use his spidey - sense and acrobatic skills to navigate Hogwarts. For example, he could swing from the castle turrets.
One great Harry Potter spider fanfiction is 'The Spider's Web in Hogwarts'. It weaves an interesting story where spiders play a crucial role in protecting a hidden part of Hogwarts. The author does a wonderful job of integrating the magical world of Harry Potter with the mysterious nature of spiders.
It can be an informant. Spiders are small and can go unnoticed. In fanfiction, a spider familiar could eavesdrop on conversations, especially in places like the Forbidden Forest or in the dungeons of Hogwarts. It can then convey the important information it has gathered to its master. This would be really useful for a character involved in some sort of mystery or intrigue at Hogwarts.
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.
You might expect a lot of creativity. For example, Harry could have the ability to climb walls like a spider. His magic could be combined with spider - like features. Maybe he could spin webs using his wand or some newfound power. It would be a strange but interesting blend of the magical world of Harry Potter and the more mechanical or biological aspects of Spider Splicer.
Perhaps there's a story where a young witch has a spider familiar that she uses to spy on her enemies. The spider can crawl into small spaces and overhear conversations, then relay the information back to the witch. In a Hogwarts setting, this could be used to figure out the plans of a rival house in a competition or something similar.
