Fanfic ideas for 'Ben 10' and 'Ultimate Spider - Man'

A great way to combine them is through a shared technology. Maybe some of the tech from the Omnitrix gets mixed up with Oscorp technology. This creates new villains or new powers for our heroes. They then have to figure out how to deal with these new situations. It could also lead to some interesting character development as they learn from each other. For example, Ben could teach Spider - Man about the different alien cultures he has encountered through his travels, and Spider - Man could show Ben how to better handle the public and keep his identity a secret in a big city.

One idea could be Spider - Man teaming up with a new, original superhero created just for the fanfic. They could face a villain who has the power to manipulate time, causing chaos in New York. Another could be exploring what would happen if Spider - Man lost his powers temporarily and had to rely on his wits and the help of his friends to stop a crime wave.

One idea could be creating an OC with a unique power set related to sound, like being able to manipulate sound waves for various effects such as creating sonic blasts or using echolocation. Another could be an OC who is a foreign exchange student from a technologically advanced country and brings in new gadgets to help Spider - Man. Maybe an OC who has a power to heal others but at a cost to their own health.

Another plot idea is that the OC is a scientist who accidentally creates a new type of symbiote. This symbiote has different properties compared to Venom and Carnage. Spider - Man has to team up with the OC to control and understand this new creation, leading to a lot of action and character development.

In an 'ultimate spider man crossover fanfic', a really interesting crossover could be with Venom. But instead of being enemies, they team up. Maybe there's a new symbiote - like threat that is even more powerful and they have to combine their powers to defeat it. Another idea is a crossover with the Guardians of the Galaxy. Spider - Man gets accidentally transported into space and has to team up with Star - Lord and the gang to get back home while also fighting off some space - pirates.

One interesting crossover could be Ben and Spider - Man teaming up to fight a common villain like Venom. Ben could use his various alien forms to take on Venom in different ways, while Spider - Man uses his web - slinging and acrobatic skills.

One idea could be a story where Miles Morales has to team up with an alternate version of himself from a dimension where he never became Spider - Man. They have to overcome their differences and learn from each other to stop a new villain that is threatening all the spider - verse.

Maybe there's a plot where an ancient artifact is discovered in the city. This artifact has a connection to White Tiger's heritage. Spider - Man and White Tiger must protect the artifact from a group of thieves who want to use its power for evil. As they guard it, they learn more about each other's pasts and grow closer as friends and allies.

Maybe a fanfiction where all the Spider - Men and Women from different spider - verses team up to fight a common enemy that threatens all of their universes. It could be a powerful cosmic entity that is consuming the multiverse, and they have to combine their unique skills and knowledge to stop it. This would allow for a lot of cool interactions between the different characters.

Another idea could be a story where Spider - Man has to help Ben 10 when the villains from his world start causing trouble in New York. They would have to combine their different skills and knowledge to protect the city and stop the bad guys.
