Fanfiction ideas combining Zootopia and Spider - Man
Another fanfiction could involve a Zootopia character getting the powers of Spider - Man. For example, Judy Hopps could accidentally be exposed to the same radioactive spider that bit Peter Parker. She then has to learn how to use her new powers while still maintaining her duties as a police officer in Zootopia. This could lead to some interesting scenarios where she has to balance her two identities, much like Peter Parker does.
A more complex fanfiction could be set in an alternate universe where Zootopia is a part of the Marvel universe from the start. Spider - Man could be a regular visitor to Zootopia, and he teams up with some of the local heroes (like Nick Wilde and Judy Hopps) to fight threats that are common to both their worlds. This would involve a lot of world - building and exploring how the different species and powers interact.
One idea could be that Spider - Man has to save Zootopia from a new villain. Maybe a super - intelligent criminal who has found a way to control the minds of some of the animals. Spider - Man would have to use his web - slinging skills and his intelligence to stop this villain without causing too much chaos in the city of anthropomorphic animals.
Fanfiction ideas combining Spider - Man and One - Punch Man
One idea could be a crossover where Spider - Man and One - Punch Man team up to fight a common enemy. Maybe a powerful villain from the Spider - Man universe has somehow made its way into the One - Punch Man world and is causing chaos. They could learn from each other's fighting styles. Spider - Man with his acrobatic moves and web - slinging, and One - Punch Man with his overwhelming strength.
Fanfiction ideas combining Spider - Man and Guardians of the Galaxy
One idea could be that Spider - Man gets accidentally transported to the Guardians' part of the galaxy. He teams up with them to fight a new threat that is endangering both Earth and the various planets in the Guardians' territory. His unique abilities, like web - slinging, would be an interesting addition to the Guardians' combat style.
Fanfiction ideas combining Danny Phantom and Spider - Man
One idea could be that Danny Phantom gets transported to the Spider - Man universe. He could use his ghost powers to help Spider - Man fight villains that are a bit more supernatural in nature, like Mysterio when he's using his illusions. Danny could phase through objects to avoid attacks and then surprise the bad guys.
Fanfiction ideas combining Harry Potter and Spider - Man: Homecoming
Maybe the Venom symbiote could find its way into the Harry Potter universe and attach itself to a wizard. This wizard would then have to struggle with the dark and aggressive nature of the symbiote while also dealing with the magical world's rules and expectations. Harry Potter and his friends would have to figure out how to separate the wizard from the symbiote without using traditional Muggle technology.
Fanfiction ideas combining Harry Potter and Spider - Man: Homecoming
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.
Fanfiction ideas combining Naruto and Iron Man
One idea could be that Iron Man creates a special suit inspired by Naruto's ninja abilities. For example, he could develop a suit with the ability to perform shadow clones like Naruto. This would give him an edge in battles as he could send out multiple versions of himself to confuse enemies.
Fanfiction ideas combining Steven Universe and Iron Man
One idea could be that Iron Man somehow ends up in the Steven Universe world. Maybe his technology malfunctions during an experiment and transports him there. He could then use his tech knowledge to help the Crystal Gems with their battles against the Homeworld gems. For example, he could create new types of shields or weapons using the unique materials in the Steven Universe world.

Fanfiction ideas combining Iron Man and Justice League
One idea could be that Iron Man's technology gets mixed up with Justice League's alien tech. Maybe he creates a new suit using some of the Kryptonian crystal technology he discovers while working with Superman. This new suit gives him powers similar to Superman for a short time, but it also has some unexpected glitches that lead to humorous or dangerous situations.
Fanfiction ideas combining Harry Potter and Pillar Man
One idea could be a crossover where the Pillar Men are somehow transported to the wizarding world of Harry Potter. They might initially be seen as a threat, but then find common ground with some of the darker wizards who are interested in their unique powers.
