A Naruto and Rick and Morty crossover fanfiction might start with Naruto somehow ending up in Rick and Morty's dimension. Naruto would be confused by the strange technology and the different species. Rick would initially be dismissive of Naruto but soon realize his potential. Morty would befriend Naruto quickly. They could then team up to stop an evil force that wants to use Naruto's chakra for its own nefarious purposes across different universes. The fanfiction could explore how Naruto's ninja ethics would clash or blend with Rick's amoral scientific experiments and Morty's simple morality.
Imagine Rick figures out a way to use chakra in his own inventions. He and Morty could end up training with Naruto and the others. Rick would be impatient with the slow progress of ninja training at first. Morty would struggle to keep up with the physical demands. But as they progress, they could introduce new ideas to the ninja world like interdimensional travel for ninja missions. And in return, Naruto could teach them about the power of friendship and loyalty in a way that changes Rick's and Morty's perspective on things.
Naruto and Rick are quite popular. Naruto's positive and determined nature contrasts with Rick's cynical and intelligent personality. Their interactions can lead to really interesting storylines, like when Naruto tries to understand Rick's complex technology and Rick is bemused by Naruto's unwavering belief in his friends and his ninja way.
Well, in the world of fanfiction, people can take characters in all sorts of directions. But in the context of 'Rick and Morty', the idea of Rick abusing Morty in the fanfiction is a deviation from the show. The show focuses on their interdependent relationship, with Rick being the brilliant but flawed mentor and Morty being the somewhat naive sidekick. Fanfiction writers might create such scenarios to explore the darker side of their relationship, but it's not a part of the main narrative.
Rick would be the most interesting. His unpredictable nature and vast scientific knowledge would create a lot of chaos and new possibilities. He could mess with Naruto's world in ways that no one else could, like creating new types of jutsu through his technology or transporting Naruto to bizarre dimensions.
A fanfiction could focus on Summer from Rick and Morty meeting Naruto. Summer might be intrigued by Naruto's world and his powers. They could go on an adventure where Summer tries to learn some ninja techniques from Naruto, and Naruto learns about the advanced technology in Rick and Morty's world.
Well, one possible plot could be that Rick accidentally opens a portal to the Inuyasha universe while trying to find a new energy source. Morty gets dragged along and they meet Inuyasha and his gang. Maybe Rick's advanced technology could be mistaken for some kind of powerful magic by the characters in the Inuyasha world. And Morty could befriend Shippo, since they are both kind of the sidekicks in their respective groups.
A cool Rick and Morty crossover fanfiction idea is with 'Back to the Future'. Marty McFly could end up in Rick's dimension and they could team up to fix some time - space continuum issues that Rick's inventions caused. Or a crossover with 'The Simpsons'. Homer could be awed by Rick's intelligence and Morty could make friends with Bart. Also, a crossover with 'Star Trek' would be amazing. The crew of the Enterprise might be both intrigued and horrified by Rick's unethical scientific experiments.
In a Rick and Morty Superjail crossover fanfiction, Rick might start trading his inventions with the warden of Superjail. The warden could be interested in Rick's portal gun to bring in new and strange inmates from different dimensions. Morty would be dragged along and might form an unlikely friendship with some of the more 'human' inmates, sharing his stories about his adventures with Rick which the inmates would find both crazy and fascinating.
One possible plot could be Rick getting accidentally transported to Superjail. He would then use his scientific genius to try and find a way out while also causing chaos. Morty might follow him and they'd have to deal with the insane inmates and warden of Superjail. Maybe Rick would try to make a deal with the warden using some of his inter - dimensional gadgets.
