A really cool plot could be a fusion of the two villains. Bill Cipher from Gravity Falls could team up with the Galra from Voltron. This would force the heroes from both universes to work together. The Gravity Falls gang and the Voltron Paladins would have to combine their strengths, such as the Gravity Falls group's knowledge of magic and the Voltron team's combat and piloting skills, to defeat this powerful alliance.
One interesting plot could be the characters from Gravity Falls getting involved in the Voltron universe's battles. Maybe Dipper and Mabel accidentally stumble into the world of Voltron while on one of their mystery hunts. They could use their unique skills, like Dipper's knowledge of the supernatural and Mabel's out - of - the - box thinking, to help the Voltron team in unexpected ways.
Well, I think Lance would be really intrigued by Mabel. He'd probably be impressed by her colorful sweaters and her positive attitude. Mabel, on the other hand, would be excited to meet a real - life space hero like Lance. She might even try to set him up with one of her friends in Gravity Falls.
The merging of the two different settings. Gravity Falls has its own spooky and mysterious forest and town, while Undertale has the Underground with all its unique areas like Snowdin and Hotland. When these two settings are combined in a fanfic, it creates a whole new world full of possibilities. For instance, a fanfic might have a scene where the characters are exploring a part of the Underground that has been influenced by the mystery of Gravity Falls. This could lead to some really unique and unexpected story developments. It also allows for a lot of creativity in terms of how the rules of both universes interact.
The clash of two very different universes. SCP is dark and full of strange, often dangerous entities, while Gravity Falls has its own brand of mystery but is more family - friendly at first glance. So seeing how the characters from Gravity Falls react to SCP - type threats is really interesting. For example, Dipper's curiosity might get him into trouble when dealing with SCP objects.
One idea could be a Gravity Falls and Steven Universe crossover. Dipper and Mabel could meet Steven and the Gems. Maybe they'd team up to solve a mystery that involves both Gravity Falls' strange phenomena and the Gem-related threats. It would be cool to see how the different magical elements interact.
I think Tommy and Dipper would be a really interesting pairing. Tommy is the fearless leader among the Rugrats, and Dipper is always eager to solve mysteries in Gravity Falls. They could combine their skills and curiosity to explore new areas in Gravity Falls or figure out some strange happenings. Another cool pairing could be Angelica and Pacifica. Angelica is used to being bossy, and Pacifica has her own airs, so it would be fun to see them butt heads or, surprisingly, become friends.
One of the most interesting plot twists could be when the characters from Gravity Falls and Reverse Falls have to team up against a common enemy they didn't expect. For example, a new supernatural force that threatens both their worlds. This would force them to put aside their differences and work together, which is a big change considering the nature of the two settings.
Well, a great plot might involve Bill Cipher from Gravity Falls making a deal with a crossroads demon in Supernatural. This could lead to a chaotic situation where the rules of both universes start to blend. For example, the symbols and spells in Supernatural might start to have an effect on the Gravity Falls' magical creatures, and vice versa.
The crossovers where the Avengers have to deal with Gravity Falls' supernatural villains are really interesting. For instance, when they face Bill Cipher. It's fascinating to see how the Avengers' powers stack up against such a powerful and otherworldly foe.
One interesting part is the blend of two different universes. Gravity Falls has its own set of rules and mysteries, and Naruto has his ninja world full of chakra and jutsus. When combined, it creates a whole new set of story possibilities. For instance, the way the Gravity Falls characters might react to Naruto's superhuman strength and speed. Also, the fanfiction can explore how Naruto's values, like his never - give - up attitude, would influence the events in Gravity Falls.
Grunkle Stan and Toriel could be an interesting pairing. Grunkle Stan is a bit of a con artist but has a good heart deep down. Toriel is a motherly figure. They could have some great interactions where Toriel tries to get Stan to be more honest and kind, while Stan might try to find some business opportunities in the Undertale world. It would be a clash of personalities but also a chance for growth for both characters.
