What could a Gravity Falls and Rick and Morty crossover fanfiction be like?

One possible plot could be that Rick and Morty accidentally portal into the Gravity Falls universe. They meet Dipper and Mabel, and Rick's technology starts malfunctioning because of the strange magical forces in Gravity Falls. Morty and Dipper team up to try and fix it while Mabel tries to get Rick to participate in some of her wacky Gravity Falls activities.

In a crossover fanfiction, Rick could be intrigued by the strange anomalies in Gravity Falls. He decides to study them, dragging Morty along. They run into the Pines family, and Rick starts making deals with Grunkle Stan to get access to some of the more mysterious areas of the town. However, his actions start to awaken some long - dormant and dangerous entities in Gravity Falls that both sets of characters have to deal with.

Definitely Rick and Dipper. Rick is this super intelligent, jaded scientist who has seen so much of the multiverse, and Dipper is this young, eager mystery - solver. Their interactions would be really interesting as Dipper would be constantly asking Rick questions and Rick would be either annoyed or reluctantly impressed by Dipper's inquisitiveness.

Rick and Dipper would be really interesting. Rick's cynical and scientific view would clash with Dipper's curious and somewhat naive nature. Dipper would be both fascinated and a bit intimidated by Rick's intelligence and his access to other dimensions. Rick might see Dipper as a young, impressionable mind that he could either corrupt or mentor in a strange way.

Rick and Grunkle Stan would be really interesting. They're both kind of cynical in their own ways. Rick could be dismissive of Stan's 'hustles' at first, but then they might find common ground in their experiences dealing with the strange and unknown. They could end up swapping stories about the weird things they've seen in their respective universes.

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.

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.

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.

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.
